Reincarnation no Kaben

Reincarnation no Kaben follows Touya Senji, a young man who has struggled his entire life with a perceived lack of talent. Despite his relentless efforts, he feels destined for mediocrity. His ordinary world is shattered when he encounters Haito, a formidable Kendo champion who reveals herself to be a protector of humanity.

Haito's power stems from a mysterious ability called the Stem of Reincarnation, which allows her to access the skills and knowledge of her past lives. This incredible power, however, comes at a terrifying price: activation requires a drastic, self-inflicted act. Drawn into a hidden conflict, Touya finds himself at a crossroads as Haito sees potential in him that he never knew existed, challenging everything he believes about himself and his place in the world.
