Toshinari Seki

The boy who sits next to Yokoi and is always playing around with something in the middle of class. He is very dedicated to his games and makes things with attention to every little detail. He believes in all kinds of occult things, supernatural activity and fortune telling. As Yokoi mentions, in his games he often picks on the weak. Surprisingly, he never gets caught by the teacher.

He has a little sister Jun. Despite the fact that he can easily ignore her during his games, he cares about her.
