Tenko is a relatively calm and shy teen who often makes irrational decisions driven by his emotions. He has messy, unevenly-cut, greyish-blue hair which barely reaches his shoulders, pale skin and bright, cherry-red eyes. He's also 5'7". His quirk, which is called 'Decay', allows him to disintegrate whatever he touches with all five fingers. This decay spreads quickly, allowing him to turn whatever he pleases to ash and dust if he maintains contact long enough. His chosen hero name is Fracture.
