Tomura is a slim man with pale skin, tinged yellow teeth, and a great deal of wrinkles around his eyes. His lips are chapped and uneven, a small mole on the right underneath, with visible scars on his right eye and under his lip. He has messy grayish-blue hair of varying lengths, the longest clumps reaching to about his shoulders, left hanging over his face in uneven waves. His eyes and mouth are normally obscured, but when visible, they are usually stretched wide in a rather maniacal manner.
