[Crossover] 100% Caught in the Crossfire

My name is Sawada Kotoha. I have extraordinary fighting skills and an extraordinary older brother, but in my everyday life, I'm still an ordinary middle school student most of the time. But at some point, I seem to have developed a strange constitution. One day, I went on a trip to Yokohama with my classmates. As we passed a fight, one side suddenly attacked me: "Quick, she's the Tenth Vongola Boss's sister! Kill her and pin it on the Port Mafia, and the Port Mafia will be finished! Hahaha!" Me: "..." One day, I was shopping on the street when a targeting mark suddenly appeared between my eyebrows: "Choose. Save this little girl, or save everyone in the building, great~ de~tec~tive~" Me: "..." Another day, I was flying over Japan when three red marks suddenly appeared on my hand: "Looks like Little Leaf has been chosen as the seventh person..." Me: "..." Another day, I passed by a certain suspension bridge just as some bandage-wrapped weirdo jumped off. The bridge shook, and somehow I fell off too. A head popped out of the water: "Ah, Kotoha, over and over again, you keep trying to die with me. It's just so, " I punched him in the face, expressionless. "Shut up, you menace! Nine out of ten times I'm unlucky these days, it's because of you!" Pairing: Dazai. A story that develops through a mix of attempted suicide and being unwillingly dragged into a double suicide. [Kotoha: wipes away tears.jpg] Theme: As long as life goes on, keep striving to improve yourself.
