2 volumes long from 2008
The Project MP gag comedy centers around a high school boy who is friends with a number of girls, but he is otherwise ordinary. One day, he discovers that his teacher has formed a sentai (combat unit) with the girls in his school — and that he is one of their targets in their battle against evil.
I couldn't find too much about this series online, but I love gag type shonen stories and japanese sentai shows, so I wanted to suggest this series for Jnovel to look into. Its only two volumes from what I could find so maybe its worth checking out.
