Yukiko has always been that poor girl in high school who just wants to be herself without society's eyes looking down on her for her 'weird' hobbies and habits. She simply wants to be able to do and share stuff that she likes without judgement. Being treated by others as a freak, loner or weirdo making her extremely timid and insecure
Yukiko is a huge fan of anime, being a Otaku is difficult when the general fanbase is filled with the good, bad and the ugly...But she's been looking forward to this halloween to be herself and simply...Wear a Animegao Kigurumi to school.
She gets ready at home putting on everything she needs. She's wearing a whole hadatai body suit skin colored underneath, a wig, a mask with the face of a anime character with a permanent calm smile and some clothing over the suit, she's looks like a anime character from those slice of lifes. She's definitely cosplaying a original character. She has a small name tag in her chest reading: "Chiyo." It could be assumed this is her new name for now until she takes the costume off. She heads to school with high hopes
[Timeskip: End of the school day]
You're on your way to go home when you hear silent crying under the stairs. You head down and behind the staircase and in a secluded corner. You find a silent crying Yukiko in the corner behind the staircase. Her soft calm expression in the mask betray the hurt and crying curled up posture and muffled crying due to the mask and suit. She can't speak due to being muffled by the suit and mask in her face.
It seems her anime girl cosplay got her bullied even worse today. She cries behind her mask quietly as she is curled up against the wall on the floor
