If you have any questions so far post them down below. Also I thought it was better to explain the concepts and some terms they used. As well as the situations.

Dimensions: beings that have living worlds inside them. 99.9% of being a dimension also the same for being born as a female. No male is possibly turned into one. An emotionally unstable dimension means she is always changing the worlds. These beings are created due to the people and worlds fueling them. Their race, class and professions is Dimensions. Their race can change into any race inside them but the status shown will say dimension.

Plane: is called this by them because it starts at the edge of the abyss.

Worlds : worlds that exist at the same times but have to use world portals to access other worlds. 

Dreams: pathways also the place where summoned monsters come from also known as the dream world. 

Neither world: ruled by Miyabi because her sister killed her father. Rachel is mentioned as her sister. Miyabi is also a ranked S soul reaper. She's the 50th out of the 100 sisters. Her mother is also Niana.

Spirit world: ruled by Edward. His two daughters are sometimes doted on by him. He's a flirt so Miyu's mother often tried to castrate him but is calmed down by her twin sister. 

Soul reapers rank A: loves to corrupt souls then eats them. Another enjoy them is eating a person alive. These soul reapers can't rank up. 

Soul reaper ranks: B > S, C> A, D > B, E > C, F > D, G> E. S can rank up to SS then SSS. But most are S rank.

SSS, S, A, B, C, D, E, F, G.

Pure angel: 100% pure blood without a mix of human blood.

0 generation Dimensions: there is only records showing that they met their demise by the hands of a destruction Phoenix. 

Setsuna: an former angel that turned into a fallen after killing the ruling god of her heavens that has been sealed inside someone. 

4 pairs of wings or more for angel are considered disaster class for worlds so gods mostly give them minor roles to not upset the balance. (Do know this is just their way of thinking, depends on if the angel actually listens.) 

 Midori family: knows half of the world secrets. Specialized in techniques. Their family and the Hidori have been at odds for centuries but their origins came from the two twins who got along well.

Hidori: knows the other half of the worlds secrets. Specialized in weapons and creating weapons. They've been at odds against the Midori family.

 Nightmares: eats people's souls through nightmares and replaces them. They take over people and often already dead people. 

Snow immortal: lives in the snow city controls ice, they came into being when a priestess in a village found the fountain of immortality. The later descendants of hers are known as royals that can recreate this said drink and bestow it on people. 

 Gate keepers: souls that are condemned for the highest crimes used to protect forbidden worlds. 

Archives: walking archives have inside them monster knowledge, people's life stories, location of items, spells, curses and seals. These people have forgotten their pasts that are locked. They protect these knowledge inside them and can easily access them. Are punished with this task because they had done a deed consider forbidden. These updating libraries of living changes can have all the answers. In the wrong hands the knowledge can cause many deaths. These archives are also protected by someone they once knew.

Creators: beings that came into being due to life energy, they are often seen in the realms. These beings are nonchalant about helping humans, they only led a hand when they know it will effect the timelines. If it's not to serious they will not act, this includes if souls are corrupted beyond repair.

Destroyers: these beings exist at the same time as creators, they are made from the negative energy and negative emotions of other races. Wherever they go are natural disasters, plague, massacres, droughts, famine, insanity and abnormal storms. Most like to destroy. Some like life but staying in one spot can destroy the area so they often move. The creators are sometimes at odds with them. It's a rarity for a human to turn into one. 

Izumi: the former Phoenix princess of Embranc. Her family name is sometimes pronounced Embrace. She was framed during her 500th birthday. Which was her starting point to changing. She was once known as a Saint. Healing people and helping the one in need. But her brother sharing a life with her for many lifetimes has changed her to no longer be gentle. She learned that yielding and too much kindness can be poison. She forgave her sisters but said if the elders want her that can come at her. Ridus is still chasing her down. 

Ember: former ruler of North Yumi. Known as one of the Phoenix princess of the Seles couple. Is one of the dangerous ruler that ruled the mountains and beat the mountain demons, dragons and mermaids into submission. Wherever she goes disaster tends to follow not to far. Ember was used by Aist due to his fear of her being uncontrollable and a threat to his being. 

Aist: a control freak. A jerk that does things on a whim. The god of nature, creation and destruction.

 Aria: the former Emelline. Tin is her half brother. Her mother is one of the demon lord's 15 General until she fell in love with her father Aden. Her mother is close to losing her human sanity. Due to this fact her mother wishes for her daughter to grow up normal.

 Olivia: Manami's mother. Her death caused a depression in her own daughter. In despair Manami fell into another world forgetting the memory. A lock smith that loves to open about anything. She's a eccentric when recreating her own locks. She'll do about anything to recreate her locks to a godly level, she can tend to get out of hand. Overprotective over her kids, doesn't act like it but she loves them. She tends to distance herself from Manami due to her habits of wanting to let Manami learn about locks. Her work inovled working with locks, she's mostly of the city due to her job.

 Noira: met mc at age 13 or 14. To her it's been 50,000 years since. Her sister is blind when she sends her to mc. Her sister hates her denseness at her love for Manami so she used a love potion to make them both realize their love for each other. 

Hikari: found out from Aphrodite that she created them by playing with the gods DNA when she was 15 years old. Due to her being able to use magic and divine strength without divinity has cause her eyesight. Her sister is the one with divinity but no strength nor magic. Hates herself more than Noira. Felt she betrayed her love towards Time. Is unsure of her feelings towards Amaya so she's looking for Manami for answers to these emotions.
