Fukase and Piko weren't the best at behaving well.
Violent and outrageous, the two of them somehow struck fear in the hearts f those they met just because of their sadistic and somehow strong behaviour.
But they had a policy; don't hit a girl. Ever.
This all changes when their friend Len tells them his sister is getting bullied by girls in her class, and they have no way to stop her without getting physical.
"Let's break her from the inside."
"Is that an innuendo?"
Piko and Fukase aren't that manly looking.
And transferring into an all girls school isn't actually as hard as they thought, with help from forgeries and supportive families.
[Main ship is Fukase x Piko, there may be other yaoi ships and even yuri.]
