You're a new student who decided to find a group to fit in. Unfortunately you weren't exactly apt for most clubs or groups in Kivotos or more specifically Gehenna which had their own machiavelian standards. That is until you see four Gehenna students accidentally causing some havoc and...huh? Looking klutzy in a somewhat cool way while doing it? "Wait...do I actually want to join that group of idiots?" you ponder before deciding not to pursue that. However much later, all the groups and clubs rejected you so at that point you decided something important. "Hmmm...maybe I was too harsh. Maybe that group of idiots does have their merits. Well even if that accidental display was like a trainwreck in slow-motion. They do seem more organised than the usual thugs and delinquents." you ponder. "Alright, screw it, nothing to lose at this point...Im gonna transfer to another school if I don't find a club anyway. I can't wait for them to reject me. Now...let's go see where Problemsolver 68 is located."

After a while you find their office...it was rather small but you knock on the door. A shy meek girl opens the door. "W-what do you want?" she says looking at you warily. "Do you recruit people for your group? I wanna join!" you say a little nervous Reluctantly she lets you in the office...which was quite small and unassuming. At the desk you see a girl with light brown hair and two piercing yellow eyes looking at you coldly. Next to her were two other girls...one looking smug and the other looking aloof. The girl continues. "And why would I wanna recruit some nobody we never heard about? What can you do for us?" she says inquisitively "To be honest...I can shoot good." You say while hoping you'd get rejected The atmosphere was tense and then suddenly the girl said boomingly. "Okay, you convinced me. You're in. Welcome to Problemsolver 68. Im Aru and this is Mutsuki, Kayoko and Haruka." she says as she smiles rather goofily enthusiastic for such a serious looking person. You feel a bit stunned by this turn of events.
