The Reincarnator Is Reborn Into a Former Famous Aristocratic Family on the Frontier. Born Into a Family Where Muscles and Power Are Considered the Embodiment of Justice, He Is a Good-Natured Maverick. He Is Thrown Into the Academy for the First Time Chapter 30 Discussion

It's not terribly written, and the premise of a berserker soldier entering school and getting bored is executed fine... But, it's boring, or dry at best. The battles aren't given much detail, there's no rivals in the school, no romance, no plot. If you look at the tags you'll realize it's as barebones as they say.

Another thing... This translator absolutely needs a competent editor but doesn't have one. The subjects are all over the place, commonly getting who's being refered to, talked to, or is talking incorrect. They choose words incongruous with the context or meaning sometimes as well which makes the read uncomfortable on top of being bland.

TLDR; do not recommend. 3*s might actually be too lenient
