Hugo Baint von Renxandt, born Natsume Kengo in a prior existence, undergoes a stark evolution shaped by unchecked ambition. As Natsume, his life was driven by an egotistical and abrasive nature, habitually testing limits yet restrained only by his steadfast friend Issei Sakurazaki.

Reborn as the Renxandt Empire’s crown prince, Hugo wielded his royal status without restraint, emboldened by unchecked authority that spiraled into tyranny. His reckless actions peaked in a botched assassination of classmate Shun, costing him his powers. The failure ignited not repentance but a vengeful obsession, driving him to seek demonic alliances.

Exploiting infernal forces, Hugo orchestrated the Analeit Kingdom’s downfall and besieged the Elf Village, unwittingly manipulated by the enigmatic White to advance her faction’s war against the elves. His schemes collapsed in defeat. After timeline fractures mended and brainwashing dissolved, a lucid Hugo faced the full weight of his atrocities, voicing raw remorse for the destruction he unleashed.
