sekomumasada sensei

Full name: センチメンタル小室マイケル坂本ダダ先生 (Sentimental Komuro Michael Sakamoto Dada-sensei)

One of the more popular and recognized NPCs from Yume Nikki. His signature characteristics are his monochrome-ness, clothes that only expose his head and neck (And sometimes his hands), and severely lazy eyes, both of which usually point away from each other diagonally. In the game, he's found inside of a strange, white spaceship that contains a piano beneath a panoramic view of space, a table and some chairs, and a bed.
