Zongman: People in Conan, raising cats and mice

Matsumoto Akira, who came to the world of anime for no apparent reason, originally planned to live a normal life according to his own wishes, but the sudden weekly anomalies caused some ripples in his originally beautiful and peaceful life. (The worlds involved may include Conan, Strange Girlfriend, Love, Chunibyo & Other Delusions, etc., and more can be added later. If you need, please tell me)...
