Comprehensive Comic: Got Hit by a Hatchet at the Beginning

Bai Yi, an ordinary high school student on Blue Planet. After transferring to another school, his normal life began to become strange. Nakano Sanjiu: "Bai Yi! You have to teach me how to learn!" OS: Otherwise I will kill you! Mai Sakurajima: "Hey, Bai Yi, I need your help with something." OS: They are all tasks issued by the system, there is no other way. Furutagawa Nana OS: I will never lose you again after rebirth... Euclidean Halsides: "Bai Yi, there are demon-free undead spirits in the underworld again, hurry up and clean them up!" Bai Yi expressed shock: "There are two-dimensional girls appearing on the blue planet. It seems that my dream seems to be hinting at something..." … Ps: main daily, sub-combat. Because the main world is a blue planet, other settings may be different from the settings you watched in the anime before. I hope you, the readers, will bear with me.
