Ritsuko Hagiri

Background
As a professor at Reinan's SP, she teaches the Ranged Combat Course. She becomes the new Dean of Reinan's SP program after the events of book four.

Ability
Ritsuko is a master markswoman, with an uncanny ability to use virtually any common object as a lethal projectile. By coating objects with her ki (i.e.marbles, dice, darts) she can shoot them as if they were bullets. Her innate ability to throw any projectile with great unerring accuracy and deadliness borders on superhuman. Allowing her to defeat multiple opponents. Their power is enough to blast through walls and pierce human skin. She can also control the density of any object she fires, its weight, and how fast it will shoot.
 * Death Print Bull's Eye (死紋十字斑, Shi Mon Jū Ji Han, translated as Death Crest Cross Plaque): Ritsuko’s special technique that allows her to manifest bullseye targets on various parts of an opponent's body. Any projectile Ritsuko shoots from then on will relentlessly chase its target. Ritsuko thus no longer has the need to aim and can release volley upon volley of projectiles while maintaining her distance. She can use any movable item as her projectiles, like driverless trucks, blades of grass etc.
