Doors

Doors (扉 Togira) is an Emitter type quirk used by Adachi Yuudai.

Description
Yuudai can create a limited amount of doors from scratch; these doorways are more fragile but give him more precise control. They must go to somewhere Yuudai has been before and can clearly picture. They require the most energy and concentration but once in existence correctly, he can manipulate them as he pleases. They degrade and must be recreated over time.

Yuudai can also 'steal' doorways. He can only store a certain amount  before they get unstable; too many and they'll become unstable and potentially 'glitch'. Theoretically, if a glitch was bad enough, he could be scattered into the fabric of space and time or torn apart.

Usage
Yuudai used this quirk to great effect during the Portal Arc. It first manifested when he was a small child when he hid from his mother.
