"I'm totally awesome. Like, duh.
Because I'm a brave hero who rescues people in distress and stuff!
So why don't women fall at my feet? What's wrong with me!!
Well fine, I'll change my job class and create a harem."
Right as he thinks that, the school falls under attack!
For some reason there are monsters in the basement.
"What basement!? My school never had that before. And now girls are being kidnapped. Something terrible... atrocious is happening to them!"
