## Description
The story is set in the prestigious all-girls' school, St. Lapis Lazuli Private Academy, attended only by the chosen few, a desired place of learning...

However, beneath this glamorous garden of maidens, an evil force lurks. Secretly, bullying is rampant. The teachers, to save face, turn a blind eye to the bullying, only thinking of concealing the problem...

Into this school comes a new teacher. Usually an unremarkable physics teacher... but his true identity? He is the masked hero of righteousness, Hyper Justice (HJ)! To hide his identity, HJ dons a distinctive costume and punishes the bullies and vile teachers one by one!

"I'm going to inject my justice into every corner of your body!"
"N-no, you just want to assault meee..."

For those who don't understand words, justice will be carved directly into their bodies!

"Why are you doing this, mister perverted mask?!"
"Wroong! I'm Hyper Justice! Never make that mistake again!"

Finally, he faces off against the root of the evil controlling the school from the shadows... but finds himself in unexpected trouble, a desperate situation! What will be the fate of the perverted mask... no, Hyper Justice?!
