Tokusatsu: The Bizarre Trainer Who Started with Super Sentai

[No female lead + nearly invincible + decisive and ruthless + tokusatsu crossover + anime crossover + game crossover + some original material]

After dying from an all-nighter, Wuluojia is reincarnated with the help of a System in the world of Samurai Sentai Shinkenger, where he becomes a half-human, half-monster being known as a “Wandering Gedoushu” and a “Half-Gedoushu.”

One day, the main story of Shinkenger begins, reviving the System after years of silence. It grants Wuluojia the technology to create and raise Makamou from Kamen Rider Hibiki.

From then on, he leads a somewhat bizarre life as a breeder and trainer, a.k.a. a weird trainer.
