Shimazu Hidetaka

Hidetaka works as a temporary teacher at an all-girls school. When he was younger, Hidetaka aimed to become a special agent, but due to the aftereffects of an accident, he had psychosis and has now given up on his dream.

For some reason, Hidetaka and his younger sister, Aki, hate each other so much that they want to kill each other. Accela, their family android, becomes the intermediary between the two.

He has a keen sense of intuition and sometimes acts as if he can see things that are not there.
