[Conan fan + single heroine Haibara Ai + assassination system + high IQ + beat up Conan + many private settings]
Traveling through the world of Kexue, Miyagawa Yoshihiko accidentally obtained an assassination list. As long as he completed the task once a week in accordance with the above requirements, he could use everything given by the system for free.
Unlimited weapons, unlimited props, and even the body has been specially strengthened...
Miyagawa Yoshihiko doesn't think he is a special person, but now that he has come to this world, he just wants to do something meaningful.
I hope that this rice flower town can purify the darkness from the washing of sin...
