Me, the School Custodian

One day, Yang Chaofan was on his way home when a falling spaceship crushed him. As his life was slipping away, he fused with an alien suit of armor and transmigrated to another world, where he became a janitor at a magic academy.

But life as a janitor isn't easy. Small-time crooks keep breaking in to cause trouble, so to avoid getting saddled with more janitorial duties, every night he transforms into Kamen Rider to fight the intruders. At the same time, he plays the supporting role, helping the guy who seems to be the real protagonist win over the girls.

But in the end, it turns out the girls' affection for him is what's going up?!

All he wants is to be a humble wage earner!
