イザミ

The Second-Ranked School Youkai. The Reaper of the 13th Step. He curses whoever steps on the 13th step to be chased for 49 days straight. He loves to preach his beliefs about enthusiasm as his prey runs from him.

If you're caught, it's over. You'll be locked away in an unearthly cage of a world, left to melt for all of eternity. He decorates his living quarters with quotes from Matsuoka Shuuzou. He's been on bad terms with the vice principal (Black Tea Gentleman) ever since he was scolded for running in the halls.

~As Izanami-sensei~

The hot-blooded gym teacher that advises the track and field club. The temporary appearance that Izanami takes when he needs a human form.

"If you've got time to worry, then run!" he spouts off his motto while driving the students to keep running with his bamboo sword. Most of the students are frightened by him, but there are a good amount of girls that are enthusiastic fans of his. He's had so much fun training the students that he's been forgetting to hunt./
