Fun lil headcanons:
Gyatts sometimes likes to call Bonnie "Bon-Bon" as a way to tease him, Bonnie hates it whenever he calls him by that nickname.
Gyatts' tail wags whenever something funny happens, especially to Bonnie but he's rarely ever seen doing it because he is always hiding behind a corner or leaned back at a wall.
Bonnie once wrapped his tail around Gyatts' waist to drag him somewhere before.
Dialogue:
(Bonnie & Gyatts are arguing)
Bonnie: Alright that's it.
( Wraps his tail around Gyatts' waist)
Gyatts: GAH- WHAT ARE YOU- AHHHHHHH
( Bonnie drags him of to somewhere)
Orobas has read a few of Warb's fanfics and it got into his mind everytime he sees demons that were included in there.
Dialogue:
Orobas Coco: (Sees Bonnie and Gyatts arguing) Oh wow, they're having their daily banter already.
(Gets imaginary fanfic scenes about them)
Orobas Coco: (Damn it! Stop plaguing my mind now will you!?)
Not typically a headcanon but a fanon incident i think?:
Garu (Magic Development Battler Captain), once left his cabinet of highly dangerous and potent potions unlocked and someone stole one of the potions and basically spiked it in a few students' drinks. Well at least there was little-no damage done to the students or anyone involved with them but Garu now makes sure to check if the cabinet is locked tight and asks the other battler members to keep an eye out for anyone who goes near it.
Yeah uh I might update this later, I have a lot more headcanons coming in later so uh yeah bye
UPDATE:
More silly headcanons:
Jazz once accidentally walked into a room that had a shrine of Iruma, accompanied with 2 demons kneeling, it was Eiko and Asmodeus Alice. He froze for precisely 6 seconds before taking a picture and shutting the door.
Warb sometimes listens to spicy audio books whenever he's doing his work, studying, or is outside.
But there was this one time in the school library when his audio book randomly connected to Lied's headphones. He was shocked by the sudden deep voice in his ears, he started to look around the library and saw Warb with his headphones on in the study area and stared at him with a confuzzled look. Warb noticed him looking in his direction and realized what happened and slowly took his headphones off and put it down with a embarrassed gulp, both of them were nervous around each other that day.
Eiko once bumped into Shaoron and accidentally dropped her notebook which had countless of pictures of Iruma and Ameri, all of it spilled on the floor. Eiko frantically tried to pick them all up and Shaoron noticed who were the demons in pictures.
(Eiko walks down the hallway with her friend Gaako when she accidentally bumped into Shaoron and dropped her notebook with pictures of Iruma and Ameri onto the floor)
Eiko: GAH! MY NOTEBOOK!
Eiko: IM SO SORRY FOR BUMPING INTO YOU
(She tried to pick them all up)
Shaoron: Wait, is that... IRUMA 'N' AMERI IN THOSE PICTURES!?
Eiko: (Nervous) UH Y-YEAH..?
Shaoron: How did you even get these pictures!? DID YA TAKE THEM YOURSELF!?
Eiko: U-UH MAYBE? HEHEHE... Heh..
Shaoron: THESE PICTURES OF PRESIDENT AMERI... ARE MAGNIFICENT!!!
Eiko: REALLY?
Shaoron: YEAH! DO YA HAVE MORE PICTURES LIKE THESE?
Eiko: UH YES!!!
Shaoron: COULD YA PERHAPS SHOW THEM TO ME LATER? I WANT TO SEE MORE OF PRESIDENT AMERI'S FULL GLORY!
EIKO: OF COURSE! IM HAPPY TO SHARE MY OBSESSION WITH SOMEONE ELSE!!
Shaoron/Eiko: YAY!!!
Gaako: Oh great, there's more of them...
