[Crossover] The Story of Her Past as an Assassin

On the third day after Tsunayoshi Sawada returned home, he picked up a woman who seemed to be an assassin. Because he gave her food, she immediately said, “I can help you kill someone.” How is that not terrifying?! According to Gokudera's investigation, she might be the ex-girlfriend of his Spartan teacher, Reborn and one of the executives of Yokohama's Port Mafia. * After losing her memories, Ayako Suzumiya found that her ex-boyfriend's attitude toward her was rather strange. Apparently, her current boyfriend was the bandaged man she had almost stepped on when she walked out the door. * The heroine really does have a blank expression. When it comes to romance, she's about as perceptive as an obtuse angle that's nearly 180 degrees (?). The male lead is a mystery. Mountains of headcanons, with out-of-character moments as a daily occurrence. Theme: Lighthearted daily life.
