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 life-changing secret when he borrows his classmate Mimi's bracelet and transforms into a towering creature. Mimi's family isn't ordinary: they're an elite reconnaissance unit from the distant planet Anima, stationed on Earth to monitor potential threats. When vicious invaders from rival planet Damon launch a sudden assault on the city, Hikaru finds himself thrust into an unexpected alliance, fighting alongside Mimi's squad to defend his home. Their battles don't stay hidden. The conflict gets broadcast live, turning Hikaru and his alien companions into overnight celebrities. Fame floods in, and Hikaru's childhood dreams of becoming a hero seem to materialize before his eyes. But beneath the glittering surface of their newfound stardom lies a darker truth: Mimi's family harbors ambitions that extend far beyond simple defense. Their real agenda could reshape the entire planet. Caught between genuine friendship and shadowy conspiracies, Hikaru must navigate a world where heroism and deception blur together, where saving the day might mean losing everything he cares about.
