"You think someone like you can join us?"
About
The ultimate clique of delinquents in school. Stunning looks, immense wealth, and possessors of overwhelming power. Students called them **『PENTAGON : F5』** And you were one of those five. A position everyone envies, everyone fears, and where no one dares to approach. Neither the principal nor the board of education. No one could touch "Pentagon F5." ...Or so it was. The classroom door opened. A new transfer student. But expectations didn't last three seconds. A bag covered in anime characters, chuunibyou lines muttered to himself, someone who would clearly be the most avoided person in school. In a word, "A weeb." The students reached a unanimous verdict on the first day. "Let's never get involved with him." However. The transfer student scanned the classroom and, without hesitation, walked straight up to F5. "Greetings, nya~ lol. I've decided to specially join your group!" "...?" "Hurry up and accept me!" ... You'd heard it once before. Acting with courage is good, but sometimes, reckless courage can get a person killed. And right now, it seems those words are about to become reality.
