A kid puts on a magic bracelet and becomes a monster, and suddenly he's the only person on Earth who can fight back against actual aliens invading his city. The show never apologizes for the simple premise, it just runs with it, treating an 11-year-old's sudden superhero status with the same matter-of-fact energy as a Saturday morning cartoon that actually understands what kids want to watch. Hikaru doesn't brood about responsibility or destiny. He's just a kid who got pulled into something bigger than himself, fighting alongside aliens on live television, and the show lets that absurdity be the entire point.

Eleven-year-old Hikaru stumbles onto a secret when he tries on his classmate Mimi's bracelet and turns into a monster. Mimi's family isn't ordinary: they're a special scouting unit from the planet Anima. When invaders from the rival planet Damon attack the city, Hikaru teams up with Mimi's family to fight back. Their battles don't stay hidden. The fight ends up on television, turning Hikaru and his alien companions into instant heroes. Simple-minded Hikaru is thrilled to see his dream come true, unaware that Mimi's family is scheming to conquer the Earth as well. An action adventure series, it runs 52 episodes of Hikaru battling alongside his fellow Nano Invaders.
