Looking for My Brother in Disguise [Crossover]

Brother No. 1 is a genius scientist who calls foolish humans monkeys. Brother No. 2 is a superpowered esper who treats his little sister like his daughter. Brother No. 3 is a charming, flirtatious, slightly sinister school idol. Brother No. 4 is a serious and meticulous school prince. Brother No. 5 is the Port Mafia's top boss, a certain short guy in a hat. With one secret identity layered over another, Haruko is an idol in the idol world, a mysterious figure in the world of special abilities, and the boss of an organization she founded in the hero world. She's doted on, and she dotes on them in return. After she falls in love, her brothers either bristle, frown, or smile darkly: "Our sister is so wonderful. How is this guy good enough for her? Let's erase him from existence!" Reading Guide 1. Updated daily at midnight. Anti-piracy protection is enabled for 48 hours. 2. Otome style. The pairing is set: Dazai. 3.
