Journey to the Moon

"After traveling through time, why can't I learn martial arts? It seems the only option is to learn cooking!" "I didn't offend you, did I? Why do you keep posting here? I have a girlfriend!" "Huh? This world is interesting, isn't it? Does it look like the previous anime?" The first world is original, followed by Xing Yue, Lelouch, God Killer, Blood Devouring Attack... Harem style, semi-invincible style. This is my first time writing a book, so please forgive me if I have any questions. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
