Ken Ishiyama

28 years old.

185 cm.

Cementoss appears to be a humanoid block of cement with black, seemingly closed eyes and grey hair tied into a short ponytail. His body shape is uniformly square throughout his body. His eyes are generally closed (but tiny when he opens them) and his lips are turned up. His hero costume consists of a sleeveless brown suit that includes yellow stripes, shorts, and an elongated collar. He also sports grey shoes with yellow soles.

Cementoss is a serious but pleasant individual. He is very careful about the well-being of others.
