Synopsis

Take your standard sentai show — colorful heroes posing, monsters exploding every week — and flip it so you're rooting for the monster. Sentouin D is a foot soldier from the villain army who's been getting curb-stomped by the Rangers for years, and he's had enough. In season one, he pulled off an infiltration scheme by disguising himself as a human recruit named Hibiki Sakurama. Now in this 12-episode second season, he's deeper inside enemy lines than ever, stuck in the Green Squadron with the job of hunting down his own kind — boss monsters who went missing long ago. His new squad includes Angel Usukubo, a fellow recruit; Kanon Hisui, their senior; and Chidori, an informant whose motives are unclear. Their first assignment drops them into an abandoned school crawling with delinquents and suspicious activity, and things get complicated fast. The real hook here is how the show treats its hero-villain divide. The Rangers aren't noble protectors, and D isn't a straightforward bad guy. Everyone's operating in moral gray areas, and the power dynamics keep shifting in ways that feel earned rather than random. If you liked the corrupted-hero angle of Akudama Drive or the meta genre commentary in SSSS.Gridman, this scratches a similar itch. Yostar Pictures handles the action well, and the urban fantasy setting gives everything a grounded-but-weird texture. It's a shounen that actually interrogates what being a hero means instead of just telling you.
