Kaede Saiba. (Shokugeki no Soma)

Step One

A short, redheaded woman (both figuratively and literally) stomped through the gates of Tōtsuki; a suitcase almost as tall being used as a battering ram for any unfortunate person that got in her way - the unconscious security guard being the prime example. 

"I'll say it again." She growled, staring down an unfortunate student who froze when everyone else ran. His friends apologised profusely in their minds for leaving him, swearing that they would maybe jump out and defend him if anything got physical. As she approached he tried to take a step backwards, fumbling when his foot failed to make it over the other and resulting in an inelegant crash to the floor. Kaede pushed her face closer to the boy, her short bob somehow falling like a curtain around them so that her terrifying yellow eyes became a focal point for his future nightmares.

"Where. Is. Soma?" She whispered, malice dripping from her words as her eyes gleamed with hatred. 

"I-I-I don't know!" He stuttered, desperately trying to appease the raging woman. She narrowed her eyes, as if not believing his truthful words before she straightened her waist. Kaede huffed, inaudible words crumbling out of her mouth as she motioned for someone else to approach and take this heap away from her. As if given orders by the King himself, someone toddled gingerly towards their fallen male peer before hoisting him up and scampering off with great speed.

"Does anyone know where Yukihira So-"

"OBA-SAN!" Soma grinned, waving wildly at the angry woman as curious heads peeked from behind him.  Most of the Polar Star Dorm were invited to welcome Kaede; some going to satisfy their curiosity after Joichiro leaving their dorm mere hours before. However, Kaede did not give a damn about the onlookers, stalking over to verbally and physically attack her nephew with anything she could get her hands on.

"Ouch! Oba-san, that hurt." Kaede's fury didn't diminish with every weak strike she gave, but after a while, she forced herself to be the 'adult' and ground her anger into a fine paste. Brushing off imaginary dust from her clothes , she bowed for the Polar Dorm residence, forcing Soma's head down as well.

"My name is Kaede Saiba. I am sorry for the trouble my nephew has caused." She spoke, using a deceivingly sweet tone to make up for the scene that they just witnessed. If anyone had not seen the emotional damage that Kaede had ladled out to both everyone and Soma, they probably would of been fooled. Kaede felt Soma struggle under her fingers, a quick chop to the head silenced him wonderfully. She reached into her pockets, bringing out a slightly crumbled piece of paper that she called her contact card to the nearest person - a long, blue haired trembling mess. 

Written on a slightly crumpled, yellowing name card was scrawled in blue ink:

Kaede Saiba 

Sister of an Idiot, Aunt of Another
