Comprehensive Manga: I, Nohara Shinnosuke, Am the Strongest in the Sacred Forest

After his death, he was reincarnated as Nohara Shinnosuke in "Crayon Shin-chan". Shinnosuke, who grew up again from a baby and had memories of his past life, thought that his biggest worries in this life were just Mi Sae's iron fist, Hiroshi's smelly socks, and how to meet more beautiful older sisters. As for aliens, time travel, magic, robots, and the Warring States Period? After more experience, you will get used to it. After all, this is the world of "Crayon Shin-chan", and everything that happens makes sense... Probably. It wasn't until the age of seventeen that Shinnosuke transferred to Seilin Academy. The new class teacher, Onizuka Eikichi. The two guys who transferred to another school with him were Takashi Mihashi and Shinji Ito. He felt that this was probably just a coincidence. Until he was punched by Hiratsuka Shizu and sent to the service department for chatting up Shizuka Hiratsuka. Then, he opened the door and saw Yukinoshita Yukino. At that moment, Nohara Shinnosuke realized. This is not a simple world of "Crayon Shin-chan" at all! And his pink-haired passerby classmate whom he had played with since childhood seemed to have something a little wrong with him. But it doesn't matter. Because he just wants to finish high school, see beautiful women, fall in love, occasionally get into trouble with his bad friends, and then go home and eat dinner cooked by Mei Xi. But the question is - why does every trouble eventually find its way to him?
