[Crossover] Jerry Mouse and Dazai Cat

The country girl Jerry from America set out for Yokohama, far from home, in search of her childhood friend Tom, with whom she had depended on each other, who had gone missing. But just as she was about to end up on the streets because she couldn't speak the language, a calico cat rescued her. The cat led her to a handsome silver-haired man in his thirties, and then... she became a member of the Armed Detective Agency. ??? What happened? Life is hard. This little mouse is bewildered. The CP is still that same man. The heroine is a gender-swapped, humanized Jerry Mouse. If that's not your thing, please don't come in. Let's all be happy. (Because someone in our sister group had their main plot idea stolen, and the plagiarist shamelessly pretended to be innocent, I'm starting to record my planned story ideas as of today. I don't remember the exact date, so I'll just start from today. --Written on 2020/05/18) Theme: Characters aimed at children are invincible! (?)
