俺、悪役騎士団長に転生する。, I, Reincarnate as the Leader of the Villainous Knight Order

The feared and ruthless knight commander, Justan, is notorious for his cold demeanor—until one day he recalls memories of his past life as a college student who cared for his seven younger brothers. Realizing that he's living in the world of a light novel destined to lead him to a ruinous end for his misdeeds, Justan sets out to change his fate. Determined to rewrite his story, he uses his well-honed "big brother skills" to reform not only himself but also the unruly knights under his command. However, his newfound good deeds start to shake the kingdom to its core. The curtain rises on a fresh isekai comic, where a reformed villain tries to save himself—and possibly everyone else along the way!
