The first two books are the ones I keep at the bottom of my box. The third one I'm reading (all three books have a system but the first one is useless). The first book. Protagonist relationship: male, Tobirama's younger brother, being treated as a girl, getting involved with Madara. A funny story. Recommended star rating: 🌟🌟🌟🌟🌟. Second book. Protagonist relationship: Just the title. Story synopsis: A male junior high school student dresses as Mikoto and starts an invincible road to raising a baby. Note: The first one is good, but I personally think that the second time-travel is not very good. And it's still good to watch and play (Orochimaru is suspected of liking Mikoto). Recommended star rating: 🌟🌟🌟 The third book. Protagonist relationship: becoming the grandson of Sarutobi Hiruzen, the naughty kid king, and never returning on the funny road~ Recommended star rating: 🌟🌟🌟🌟
