Card Game de Sekai ga Horobu Sekai ni Tensei Shite Card Shop wo Kaiten Shitara, Shuui kara Zensaku Shujinkou da to Omowareteiru

In a world where card games often lead to the destruction of the world, Tanahuda Mitsuru is reincarnated into this reality and fulfills his dream of managing a card shop. While he simply wants to observe card battles and the people who play them, others perceive him as the former shop manager who once resolved significant crises and guided young players. Mitsuru, however, has not actually dealt with any major incidents. The narrative follows his experience as a reincarnated individual who is wrongly assumed to be the previous leader responsible for past successes, despite having no involvement in them.
