Kanou Shion

Kanou Shion (加納詩苑) is a character introduced in the PSP video game Toaru Majutsu to Kagaku no Ensemble. Though deceased at the time of the game, the circumstances surrounding her death motivate Kukimoto Hibiki, the antagonist of the Science (Surface) story of the game.

Background
At some point in the past, Shion and Hibiki were the subject of research, which involved enhancing their ability to manipulate molecules by supplementing their calculation abilities with computers. However the computer wasn't able to keep up with Shion's ability, leading to an explosion, completely annihilating her.

Abilities
Shion's ability allowed her to alter the behavior of molecules. According to Hibiki, though she was a Level 0, with computer assistance she could have been as powerful as a Level 5.
