Aika Tsunaboshi - Magical Girl, Honor Student and the school Student Council secretary. Prideful, stubborn to fault, possessing a very strong sense of justice. Sometimes acts selfish and childishly without thinking deeply about things. Very self-conscious of her completely flat chest (AA cup). Despises her uncle.

The easiest way to pacify or ask Aika something is through her stomach. A fact her family and friends knows it well. Especially her uncle.

A First Year Student at Merry High. One of Merry City most prestigious schools and symbol of the city's pride. Daughter of Mr. Tsun's second marriage with Makoto Tsunaboshi.

Respects her parents to a very high regard while seeing her uncle as someone more worthless than thrash and also a stain to both the Tsunaboshi name and in Merry High esteemed history.

Hobbies: Chasing down her uncle, Sword Practice and Studying

Likes: Yozo, Fairy Tales, Sweets and Swordsmanship

Dislikes: Her Uncle, Spicy Food and Easygoing people

Age: 16

Elemental Magic Affinities: Lightning and Fire

Shinjirou Tsunaboshi - Aika and Akira's Uncle. Older brother of Akito, the school's Principal. Merry High's P.E Teacher and substitute teacher for any subject.

Laid-back, Fat, unpredictable, bit of a lecher, drunkard and now currently a Magical Girl (AKA Seraph) subbing in for his niece, who by fate of circumstance, had transferred her magical powers onto him.

Has a hardcore Maid fetish. Very self-conscious of his hair loss.

No matter how much you hit him. Shinji has extremely fast recovery rate, almost to an inhumane degree.

Owns a monstrous motorcycle, that Shinji cleans and tinkers with on a nearly weekly basis. Despite the fact that "Carmen-Chan" (Bike's given name) engine has not roared even once in the last eighteen years…

Because of a traumatic experience in his childhood. Shinji developed an intense case of Pyrophobia. Most likely reflecting as to why one of his elemental affinities is ice or perhaps something more...

Age: 47

Hobbies: Tutoring, collecting neckties, customizing his bike and peeping

Likes: Booze, Motorcycles, Gambling, Tacos and the time back when Aika used to call him ''Oji-Chan''.

Dislikes: Fire, Taxes, Censor Bars and Arrogance.

Elemental Magic Affinities: Ice and Lightning. Learned healing magic just so he could tend Aika just in case she ever gets hurt.

Akira Tsunaboshi - Aika's older brother and son of Mr. Tsun first marriage with Yuri, who was known by her gentleness towards everyone and very frail health. Her frail body could not handle the post labor and died shortly after giving birth to her child.

Possibly because of his mother said bad health, Akira has a very pale skin. Other than that, he is a completely healthy boy. A lighting-rod for misfortune and bad events.

A Third-year student at Merry High. Captain of the Archery Club. Huge introvert and Shut-in when depressed. Has the lifetime goal of making a hundred friends before graduating high school by the end of the year.

Incredibly bashful and only wears female uniform or clothing. Not wearing skirts makes him anxious and uncomfortable. Combined with his very feminine traits and the fact that he can't talk loud enough for anyone to hear. Akira is mistaken for a girl by nearly everyone in the school and even most adults.

Often mistaken for Aika's younger sister. Something neither of the two enjoys hearing.

Very gentle, incredibly shy and with unusual feminine traits, causing many to mistaken as a girl, due to his appearance and hobbies. Acquaintances of his late mother and some teachers often jokes that perhaps, Akira may have taken too much of his mother side and only took the overwhelming shyness from his father side…

Adding oil to the fire, Shinjirou often made/forced his cute and baby-faced nephew to cross-dress sell innocent photos of him since he was twelve years old in a desperate attempt sway the Landlord cousin's hunt for his rent. Causing his skirt attachment.

Because of how often their parents don't come home or are incredibly late due to both their jobs and wanting to show how he is a dependable older brother. Akira is usually the one responsible for meals, cleaning and takes care of all the housework. At Shinji's own words, "Aki is the perfect housewife. Looks like one too if you squint your eyes and pretend there is nothing dangling between his legs."

Because his overwhelmingly high popularity at school, many think Akira is out of their reach and lives in a different realm from them. Leaving Akira very lonesome as he speaks very little and quietly due to his shyness as a result. Partly by the attrition caused by other female students who are jealous of his looks and garnering attention of almost all boys in school. Most of the boys who tries to approach him is considered a bad actor and punished by his fan-club afterwards.

Likes: Archery, Skirts, Blue Roses, Fried Food and Sewing.

Dislikes: Bugs, being mistaken as a girl or Aika's younger sister and sour food.

Age: 18

Hobbies: Sewing, Cooking and Archery

Amane Setsuna - Childhood friend of Aika, Akira and Yozo.

Bookworm, diligent, usually silent with a deadpan personality, huge clean-freak, kind of a genius and a borderline Yandere for Shinjirou, fostering a near psychotic affection for the man.

Shinji is completely oblivious to it and misunderstands Setsuna affection for him as some sort familial love one would have between a daughter and parent.

She frequently invades his office to steal some of his personal belongings, such as pens or coffee mugs and even scrubs his workspace completely clean in secret when no one is looking during lunchtime or even barges in the middle of the night to do so. She recently started to do the same thing with his apartment.

Madly in love with Shinjirou from the very first time she met him back when she still was six. He used to take care of Aika more often than not back they were kids. Setsuna was frequently found next to Aika so Shinji had decided to play with her and also took care of her by proxy.

While not as much as Aika, Setsuna too is flat chested and also self-conscious of it. Although to a much lesser extent (drinks milk every morning since she was nine, hoping it would grow big enough to draw Shinji's eyes towards them in the future)

Sometimes seen drooling suddenly or nosebleeds. Having thoughts or daydreaming about her dear Shinji-Sensei. An incredibly creepy smile beams in her face and unsettling giggling can be heard while she plans how to get his attention next time or is simply admiring him from afar.

Like Aika, she is also a first year student and her classmate, sitting next to her by the window. She joined the Student Council as Treasurer per Aika request during elections.

Her family runs a well-known dojo that is treated as a historical monument of Merry City due to it age and correlations with the city very foundation.

Setsuna absolutely loves spicy food, she loves it so much that Setsuna puts spices in practically everything she eats and uses such an inhumane amount that it renders the food inedible to regular people, those foolish enough to try and take a sample of her food have their lifespan possibly shortened by a couple of years.

Her favorite food is her own homemade Tabasco ice cream, which very few lifeforms are able digest and survive such despair induced food, let alone enjoy it. Even someone masochistic to an insane degree since ancient times like Bink can't handle it, and that's says a lot.

Likes: Shinjirou, Reading, Cleaning and Spicy Food.

Dislikes: Ghosts, Small Talk, Lighting Storms and Sloppiness (except when it's from Shinji)

Age: 16

Hobbies: Stalking Shinjirou, Reading and playing the Piano

Calamity Bink - One of the 7 Seven Deadly Sins. Representing Lust. (Him being one of the greatest oppositions against Arcadia at since ancient times). Called in Arcadia old documents as "The Demon in Spandex". Flamboyant.

Hardcore masochist, very sensitive to other people feelings (sometimes thinking of them as if it was happening to himself) and sometimes rather moody. Making it very easy to make him admire a rather simple gesture or feel moved by someone's words.

Known to be the weakest of the Seven Deadly Sins. The only Sin Demon who was not sealed alongside his six brethren since ancient times, for unknown reasons.

Unlike the others, Bink is the only one with a physical body of his own and not needing to possess another living being to manifest itself in reality.

Now a former nemesis to the three and Arcadia, since he became a friend of Shinji, who convinced him to formed a truce and ally himself with Arcadia in exchange of information about the other Seven Deadly Sins and help fight against rampant demons.

Bink, in his true demonic form, has some lizard-like features. Such as revealing the he has scales surrounding his body and a forked tongue. His body is covered a bodysuit that is also part of his body.

Unlike the rest of the Demons and the Deadly Sins, Bink only became enemies with Arcadia because he was bored. Frequently annoying or disrupting Arcadia plans (giving the argument he merely lonely). He was not sealed alongside the other sin demons in ancient times for some reason and always had escaped the grasp from all Valkyries of the past to present day. Avoids answering any questions concerning the "Blackheart Calamity".

Despite losing almost a 100% of the time and successfully retreating every time they fought, that only seemed to invigorate Bink further and more enthusiastically stand against Arcadia more and more…

Shinji secretly made a promise with Bink after meeting for the first time and knowing each other better over drinks. "I beg of you. Please protect Aika from where I cannot be. Even by force if necessary!"" and "Please become friends with my nephew and help accomplishing his dream!"

"In exchange, I promise to never let you feel alone nor become bored ever again, not even for a single second! I will make sure to make you that piss yourself laughing each and every single day from today onwards!"

That is the true reason why he began living at the Tsunaboshi's attic. To fulfill his newfound friend and soon to be partner in crime request.

After his enrollment as a student, Bink immediately became so popular and thought to be so handsome by others students that he joined the school's fabled "Dual Beauties" (Akira and Yozo) the trio became known as the "Beauty Triage" in its place. Thus instantly becoming loved the female side of the school and hated by the males.

Hilariously, Bink found the male's student jealous-filled stares, burning anger and urges to kill to him worth more than gold and as something even more exciting than the female student's admirations and swoons… He was full of vigor for the entirety of his first week studying there.

Likes: Wax Candles, Whips (for obvious reasons), Bananas, Soap Operas and Reptiles

Age: ???

"Sloth" Sekihara Sei-A shut-in NEET that used to skip nearly 90% of his classes since the sixth grade. Now he currently a first year Student at Merry High and classmate of Aika and Setsuna, despite not attending a single class so far. Introvert and cynical of most people.

Age: 16

Beatrice "Agnicia" Cruz – Current Valkyrie of Arcadia. After passing the Trial of Justice and obtaining Crow's approval. She reluctantly accepted Shinji temporary enlistment, until Aika recovers Nyamo contract back from him or her curse caused by the Magekiller's eye to come undone.

Both her and Crow seem to know a secret about Shinji that he was not very happy hear they are aware of….

Very a workaholic. Only answers as Agnicia in Arcadia, giving corporal punishment on those who fail follow this specific order (usually being Shinji).

Wields rocket fueled shield which she uses as a boomerang. Her partner is Yale, the sheep with ram horns. A Firstborn Sacred Beast.

Hiden "Crow" Midori – Arcadia's current best veteran and accomplished spy. Works both as main messenger to Magical Girls and coach of freshly recruited cadets. Incredibly serious and sometimes cynical.

Despite being so serious, Crow is surprisingly carefree at given moments. Such as, when he accepted Shinji passing Arcadia's recruitment trial despite the unusual circumstances surrounding it. His flexibility and fast reasoning is one of the things Karasu, his partnered Sacred Beast likes about him the best.

Often teased by close friends, claiming he is a complete sis-con.

Lives in an apartment complex alone with his younger sister. Constantly working and looking for jobs in order to afford his college, his sister tuition, meds, food expenses, cat food amongst other life necessities (especially his sister, who he caters to her every whim. As he raises her on his own).

As a result, Crow learned many cooking techniques while on a tight budget and developed many survivalist skills that puts even nuclear dystopian paranoids to shame.

Crow was the only current Seraph at Arcadia before Shinji for the last three hundred years. He became one at the age nine. Being not only the youngest Seraph to join Arcadia but also the youngest member in general to ever be recruited.

Due to his child imagination and literally living in a fantasy setting since young, Crow developed a severe case of Chunnibyo Syndrome, albeit justified since his personal views and experiences are technically true, normal people sees him as an odd-ball, but not enough, as Crow is still incredibly popular and another gag in the story is that Crow is pretty much a "Older Sister" type magnet, coupled with his rather innocent mindset uncommon of his age and bluntness, puts the main cast in many troubles, trying to rescue him, while oblivious to igniting the envy of many men, especially Shinji and Sei's.

Has a hard time grasping social queues and unrealistic things in life as a result.

As stated before, he is incredibly popular with women, especially older women and his college classmates as well as some of his teachers.

Goes by the, alias of "Crow", both at Arcadia and in regular life.

Is a college student, aiming to become a Lawyer, has many part-times jobs since he was 12 (Bumping into him as a deliveryman, clerk, mascot or driver being a very common thing to happen).

"Mr. Tsun" Akito Tsunaboshi - Shinjirou's younger Brother and the current Principal of Merry High. His first wife, Yuri died right after giving birth to his son, Akira.

While we say first wife, the two never had the opportunity to hold a ceremony. The two promised to do it once Yuri was rehabilitated and healthy in order to do so. Her health never got better and so, Akito got engaged with her at the last minute, on same night they found out that she was pregnant with Akira.

Incredibly tall with a gigantic, muscular body tone. His giant palms can hold an entire watermelon and crush them.

Has a scary looking face that usually intimidates most people, especially first-timers, furthering his shyness deeper, unfitting of his persona and quiet yet kind composure always eases the tension of others that he manages to approach, and have not ran away afraid of him. He always looks at little hurt and depressed by someone who feel genuinely scared of him and distances themselves from him.

According to most teachers at Merry High, he has not faced his brother eye-to-eye since twenty years ago and yet one of the very first things he did after becoming the principal was to re-hired his brother as both a teacher and substitute for all classes, despite abruptly going absent and in paid leave for almost four years. Despite the perceived cold feelings and distance harbored towards each other the others around them seems to think...

Similarly, to his son, Mr. Tsun too has unusual hobbies for a man, especially for someone with that tall, rough looking built of his. He likes to do gardening and making flower arrangements. He even uses the garden's fallen leaves for tea making or medicine. Things he learned by his late wife and greatly enjoys to do since his teenage years. When not found in his office, Mr. Tsun is most likely to be found, tending the beautiful and widely famous school garden, which Mr. Tsun tends to it himself ever since he first started teaching at Merry High more than twenty years ago.

Has a second secret "job" as some sort of Crime lord which Aika only learned it on the same day her uncle gained her Magical Girl Powers. Something Mr. Tsun reluctantly does, as he also inherited this position at the same time he became the next principal.

He is trying very hard to turn a new leaf of said criminal activities in the Family and stigma that the Tsunaboshi has been carrying it for centuries.

Known by some in the city as someone as "The Bloody Giant" and very feared in the criminal underworld, the mere mention of his title sends shivers down the spine of many notorious criminals.

Age: 42

Hobbies: Gardening

Likes: Family, Fairness, Tea-Making, Apple Pie and Lilies

*Although he used to revel in it, during his short time as the "Bloody Giant".

Makoto Tsunaboshi – The Aika's biological Mother and stepmother of Akira's. School Nurse/ Science teacher of Merry High. Sometimes volunteers to help the currently understaffed school cafeteria as well.

Similarly, to Akira. Makoto is easy to become depressed or flustered. She also is very pure and innocent. Has a hard time to saying no to anyone and always willing to help someone no matter what the circumstance is.

Known as a Paragon of innocence, love, clumsiness and gentleness. Extremely gullible and might believe almost anything you tell her. Clumsy to a near dangerous degree, to the point that she often harms her patients by accident. However, they don't seem to mind. In fact, almost all of her patients consider it as some sort of blessing since it means that she will take care of them for longer.

Deeply cares for everyone around her, some mistaken her for a Saint and at times, even a Goddess because of it. Unanimously agreed to be Mother figure of the entire school. A very passionate person for what she likes, teaching especially.

Easy to befriend and comfortable towards mostly anyone, except Shinjirou. The two always seems very uncomfortable next to each other, not knowing how to respond when bumping or meeting each other down a hallway or something like it. Shinji often being the first one who avoid eye contact and avoid her like the plague ever since he came back from his disappearance.

Has an abnormally huge chest size. So big that if she starts jogging, Makoto breasts might bounce back and hit her own face (which everyone in the school jokingly remarks that her love and care towards others, even detractors, is big as the size of her chest and if you get hit by those in of her likely daily moments of clumsiness, running or tripping it, students believe that you are likely to be blessed with good luck for the rest of the week or even have a successful love confession. This superstition is believed by almost all male and female students alike. Some had their necks sprained because of it, somewhat neutering the amount of times it happens nowadays...)

Extremely clumsy. Almost set on their house on fire over 400 times and succeeded it in doing so at around 100 times (Her husban had stopped tallying the times after that so it didn't depressed Yuri even further).

Always seen wearing the trademark of his character. A pair of sunglasses.

No matter many times one tries to take or break the glasses off his face. Yozo immediately replaces them, since he carries many different pairs of sunglasses in his pocket or bag and has many more, hidden around the entire school, alongside his concealed softgun weaponry that weren't confiscated yet by Kaori, president of both the Student Council and Disciplinary Committee. Rumors that Yozo has an infinite amount of spare glasses or expected to be already wearing another pair under the other are taken as fact.
