Iori Shiromi is one of the students studying at Gehenna Academy, who wields a Sniper Rifle. She is a member of the Disciplinary Committee.

A 2nd year student and a cold-blooded specialist of the feared Prefect Team. As the field captain of its assault corps, she immediately punishes students who violate the rules with overwhelming force whenever and wherever she finds them.

While she may be efficient and formidable in combat, she is also reckless and stubborn, and is prone to losing sight of her surroundings once she spots an enemy, which makes it easy for her to fall for even obvious traps.

Strict with the rules, Iori will punish any and all rule-breakers. Although she's skilled in combat, she tends to be blind of her surroundings when engaging a target. She is also quite exhausted due to having to deal with troublemakers despite the holidays.
