任侠転生-異世界のヤクザ姫- [Ninkyou Tensei: Isekai no Yakuzahime]

In Ninkyou Tensei: Isekai no Yakuzahime (2020–present, Shogakukan), a modern-day yakuza boss is reincarnated in a fantasy world as a princess, carrying her underworld code of honor into a realm of magic and courtly intrigue. This 19-issue series blends classic isekai tropes with yakuza drama, as the protagonist navigates sword-and-sorcery conflicts with the ruthless pragmatism and loyalty of a crime syndicate leader. The series stands out for its unique fusion of feudal Japanese gangster ethos and high fantasy, offering a fresh take on the reincarnation genre.
