Second season of Mato Seihei no Slave.

Beryl Gardinant, a self-proclaimed humble old man, is a sword instructor at his dojo in a rural, backwater village. In his younger years, he dreamed of glory as a master swordsman, but those days are long behind him. Out of the blue, he receives a visit from a famous former pupil who brings him world-shattering news—he's been appointed as a special instructor for the knights of the Liberion Order! With his life now turned upside down, Beryl travels to the capital and reunites with some of his former students: elite knights, an ace wizard, and even an adventurer who's attained the highest guild rank possible. But why do they all want his tutelage?! As far as he's concerned, they clearly don't need him anymore. Can Beryl live up to his new position? And will he ever get a moment's peace away from his adoring students?! (Source: J-Novel Club)

High school student Haruka has always been a content loner. One day, he and his class are abruptly transported to another world and given skill points to use when choosing from an assortment of abilities and magical powers. Unfortunately, Haruka arrives last, and he can only use his points on the seemingly impractical abilities the others had no interest in. Although he is on his own again and must adjust to his new life by himself, he much prefers it that way. However, Haruka's peaceful solitude is short-lived, as he runs into some of his classmates. Weak to their pleas for help, he ends up sheltering and helping them reunite with the others. But the different cliques struggle to see eye to eye, forcing Haruka to find a way to end the infighting and restore harmony between them to survive the unfamiliar world.
