"All right, where's this guy who hurt his ankle?" Grim asked in a demanding matter. Y/n decided to wake up Yuuna and Grim early so they could start their investigation before classes start. Let's say that Grim wasn't too happy to wake up early, but he was now full of energy when Y/n told him that it was for the incident that needs to be solved for him to enter as a competitor.

All the talking from Grim caught the attention of two Heartslabul students who were in the back of the infirmary. One of them was the one who injured himself on the stairs, so he had a bandaged ankle over some pillows, with a tiny cup (one of those cups that medicine comes with) of phoenix tears, which were in their liquid state.

"Huh?" the injured student looked up at the small group of three. "Hey, it's the ones from Amarylis, and their hot housewarden!" his friend says. "They were at the unbirthday party!" he reminded his injured friend, who seemed to nod in recognition. "What are you guys doing here?" he asked.

"Get a load o' that! We're totally famous!" Grim happily jumped in joy at the recognition.

"It's nice to see you guys again" Yuuna smiled kindly. "Are you alright?" she asked.

"I'm alright. I broke a bone though, but the phoenix tears the nurse gave me is healing! So in a few minutes, my ankle would be good as new" the injured boy exclaimed.

"That's good. We'd like to ask about your accident. What exactly happened?" Y/n asked, crossing her arms.

The boy shrugged. "I wish I knew what happened myself, man" he sighed. "I was walking along, talking to my friend. And next thing I knew, BOOM! I was tumbling down the stairs." he explained.

"Yeah. I didn't even see him stumbling or anything" his friend says.

"It was like my body just lurched forward by itself. I can't really explain it" the boy says, a little shocked by the sudden movement of his body.

"Hm. Hmmm. Interesting. Veery interesting" Grim mumbled, thinking like a detective a bit.

"Let's go interview the next victim. After that, we need to head to class right after" Y/n says, putting away her phone after looking at the time.

"Alright. Thank you for your cooperation" Yuuna bowed as the group left the infirmary to a classroom, investigating a student from Pomefiore.

When they entered the classroom, they saw the guy talking to his friends.

"Hey, you" Grim caught the attention of the students. "You had an accident and almost got hurt real bad, right? Give us the deets" Grim says, jumping on the desk.

"And why should I answer to you, exactly?" the injured student asked. His friend slammed his fist on the desk. "He was in peak condition for the Spelldrive tournament and got hurt so bad that he can't even play now!" he said, defending his friend, but his so-called friend took it as an insult.

"And you're here to...what, rub salt in my wound?" the injured boy asked, gritting his teeth. "We trow the gauntlet! Duel us!"

Suddenly the temperature dropped dramatically, as the two Pomefiore looked toward the source of the ice-cold temperature, only to see Y/n, glaring at them with an icy stare. "There will be no duel. You better answer our questions before I, myself, give you PERMANENT injuries...am I clear?" she asked, darkly. Everyone inside the room shivered.

"A-a-all right, then, y-you highness.." the injured student stuttered shivering as well.

"Good" Y/n smiled, the temperature going back to normal.

"I-it happened in the laboratory. We were boiling up a potion when his hands suddenly shot out and grabbed the steaming hot cauldron." His friend said, explaining the incident. "He dumped out every last drop. It was bizarre! Made a real mess too."

"Oh, so YOU'RE gonna do all the talking?!" the student asked, blushing from embarrassment.

"L-let's try not to fight alright?" Yuuna said, stepping in before the Pomefiore students start an unnecessary fight. "Hmmm. Interesting. Veeery interesting" Grim mumbled.

"I hope you feel better soon" Yuuna waved to them goodbye as they walked out of the classroom, walking to their own since classes have begun.

"The Ice queen of Snezhnaya had the previous Emperor of Permafrost executed by the guillotine for tyranny and many other unforgiving crimes. A lot of events took place during and after the execution. For example, during the Execution, the famous guillotine song, Blood's refrain, was created by the very citizens watching the execution. It was a harmless chant that the Frostians (Permafrost citizens) sang during every execution that involved the guillotine, but over time, it became a dangerous curse. 200 years ago, the cursed spell that takes the same name as the chant, Blood's refrain, causes the caster to cast an illusion toward their opponent/victim to hallucinate. The hallucination is known to show the opponent about to be executed by the guillotine with a large crowd of people chanting Blood's refrain. Victims of this curse are said to feel as if time has stopped during the illusion, before feeling the pain of beheading alive. Today, the curse of Blood's refrain is known to also be dangerous to the caster because it creates a deadly amount of blot.

The Chant of the guillotine has spread all over the world, influencing kingdoms. The only reason why Blood's refrain is considered black magic is due to the curse is known to not only just cause severe harm to their opponent, but behead the opponent by touch. How? Well, while chanting the cursed song, the caster must make physical contact with their victim in order for the beheading to happen. Anyone who uses this method to kill innocent magicians and non-magicians will be sentenced to a special prison, made especially for killers who use black magic.

There are only two in the entire world. Salem and Lucifen. The aqua city of Lucifen, Land of permafrost, holds the most famous black magic prison, called , meaning, The black Hell.

I want you young magicians to do workbook page number 34 to fill out the following questions on the page. All your answers are inside of the unit we have read. So make sure to pay close attention to what you read as answers may not appear what they seem." Professor Sanderson spoke with a hint of mischief.

Soon after, the class has ended, having Yuuna and Grim back go back to Amaryllis dorm to discuss their findings, while Y/n met with Riddle and Trey, mostly because Riddle wanted some of his future wife's affection to be equal with Malleus on the level of affection she gives them. As for Trey, Y/n asked to come along with the Levia-fae making jokes like asking permission to marry Riddle (don't forget her other six soulmates) since Trey is the 'mom' of Heartslabyul.

"I dunno, this just looks like a bunch of absent-minded kids hurtin' themselves to me" Grim muttered, sitting by the fire with a teacup, filled with hot chocolate, made by the purest chocolate in the world, in his paws. "If there's a scandal here. I ain't seein' it!"

Then there was a bagging noise coming from the doors of Amaryllis. "Huh? Whozzat?" Grim asked. Yuuna stood up to see who is at the door.

"Oh? Hello Ace" Yuuna greeted. "Hello Yuu" Ace grinned. He then took his attention towards Grim. "Guess you're feeling better now, huh, Grim?" he said while walking to the raccoon, ruffling his fur.

Grim wasn't too happy about that. "Oh, it's you." Grim grumbled. "We're kinda busy right now. No time for kid stuff. Scram" he shooed.

"Busy?" asked Ace. "What, you got a lot of homework?"

"You might want to sit down..." Yuuna says, gesturing for Ace to sit down on the sofa after closing the front door of the dorm

"Injuries from suspicious accidents, huh?"

Yuuna nodded. "But nothing we heard sounded all that suspicious. It seemed like they were all just excited about the tournament, especially after knowing that Camelius is going to play against the winner...it seems that they got distracted and hurt themselves somehow" she explained.

Suddenly, the door slammed open, causing the female to flinch in surprise, summoning a flip flop, and thrown at the intruder.

"Ow!" the intruder whimpered in pain. It was Deuce. "My goodness, Deuce! You scared the poop out of me!" Yuuna says, grabbing her flip flop and having it disappear. "S-sorry, Yuu. But Ace!" Deuce shouts.

"We got a big problem!" he yelled, turning towards Ace. "Dial it down, Loosey-Deucey. What is it?" the heart boy asked.

"It's Trey and Y/n! They fell down the stairs! They're both injured, but it's mostly Trey!"

"What?!" shouted Yuuna, Grim, and Ace.

"Myah! He's the sneaky one with classes, yeah?" asked Grim.

"Hard to believe he got "distracted" too. And Y/n...she never struck me as being absent-minded. After all, she is less likely to even hurt herself from clumsiness..." Yuuna mumbled.

"Yeah, Trey and Y/n wouldn't just trip and eat dirt." Ace says. "Let's go see what they got to say!" Grim shouts, as everyone runs out of the dormitory and towards Heartslabyul.

Let's just say that once a certain dragon heard that his mate was injured...he almost burned a dorm to the ground if it wasn't for three students calming him down by proving Y/n was alright.
