Professor Kiriyu is a major antagonist in the manga Starving Anonymous. He is one of the head scientists of the Cradle and the leader of the Halycon Group. The Cradle is a secret facility where humans are mass-bred and fattened to be fed to extraterrestial creatures in order to keep them from destroying the entire earth.
Appearance
He has a rather eerie expression most of the time. His face is somewhat gaunt and he has bags under his eyes. His black hair is very short and slicked back. Kiriyu wears a black suit and tied and sometimes carries a small whip around. When he performs his experiments he dons a green surgeon coat and mask.
When he was younger he often wore a labcoat, a white shirt and a tie along with gray pants. His hair was also a bit longer and sometimes a bit messy.
Personality
Kiriyu is very ambitioned and has little regard for anything else. His dream, that he persistently pursues, is to become the greatest scientist in the world. He wants power, fame and recognition and is willing to do anything in order to achieve it. Due to this, he acts very cunning, scheming, cruel, sadistic and cold. He even used his daughter in order to gain what he wants. He mentioned however that he has no intention of needlessly causing torture, if it doesn't further his goals at all. He appears very satisfied with his actions and is proud of his twisted creations. He actually sees himself as an artist.
Beneath everything Kiriyu seems to be quite insecure actually. He could never quite reach his goals on his own and was then always outdone by Yamabiki, which led to an immense frustration and anger. So he constantly tries to appear intimidating to get respect. In order to demonstrate his determination and power he is willing to let his own subordinates kill themselves just to prove a point.
