Blue Archive: Starting Out at the School with My Teacher

[System] + [Nearly Invincible] + [A Little Chaotic] + [Follows the Plot]

A teenager came home after finishing his self-discipline routine. After losing every single one of his 480 Genshin Impact pulls to the hard pity and losing his temper over the guaranteed five-star, he opened Blue Archive. On his very first ten-pull, he got ten rainbow animations. So excited that he died from an electric shock while drinking water, he was dropped into Kivotos and, by sheer coincidence, joined Schale at the same time as that teacher.

But every member of the Decagrammaton was hostile toward him. Somewhere unknown, another Color was watching him. Caught between a wolf ahead and a tiger behind, all he wanted was to protect his students and his brothers. That alone was what truly mattered to him. But things could never go entirely his way. And yet, as if he had been here many times before, he found many things and traces of events that did not belong to the present.

(The author hasn’t decided whether to add a heroine. This book was also started after the author’s friends egged them on, so the protagonist probably won’t have any of those newly added characters.)
