شیوری یورایشینو

Even though she's just a freshman in college, Shiori is the president of the Balzak Party Supply Corporation. Her best subject is math. She's a bit shy around others, but she has great instincts for reading the room and knowing when to make her move. She loves performing magic tricks and entertaining people. Ever since the camping trip, she's been swamped with school and work, but for some reason, Gero always occupies a corner of her mind.

Devils are her trademark signature, and so most of the products she develops are devil themed.
