Mark

Overview
Mark is the protaginest of the Yume Nikki fangame S//D

Appearence
Mark has spikey brown hair that sticks out from the sides, rectangular glasses, a plain white button-down shirt with a pocket on the left side, dark grey pants, and black shoes.

Personality
It is possible that Mark hallucinates, when going out on his balcony, instead of a sky there is an abstract sort of background, and the Nexus's floor is constantly changing. He seems to be depicted as a pessimist in many pieces on fanart, or reluctance to explore.

Past
Older, Tec , and S//D seem to be connected, there is a room with pictures of Takashi and Funetsuki , protagonists of their respective games.
