The tattoo power system hooks you immediately, space warping, time manipulation, actual stakes in each fight. Episodes 1-5 are exactly what action fans want: creative powers meeting smart combat strategy, victories that feel earned. After that the show crashes into incomprehensible plot nonsense that nobody can explain, which means you're either riding the high of what worked or abandoning it entirely, there is no middle ground.

Seigi is a middle schooler with strong martial arts skills and a wish to protect the weak. When he rescues a homeless old man from street thugs, the stranger thanks him by burning a tattoo onto his palm. The mark turns out to be a secret weapon that grants supernatural powers, including the ability to warp space-time. Soon Seigi meets Izzie, a female American agent whose job is to recover these tattoos, and he chooses to help her. That choice pulls him into a conspiracy that crosses national borders. Other people want his tattoo too, among them a formidable girl who carries one of her own. With martial arts alone no match for super-powered opponents, Seigi has to unlock what his tattoo can do if he wants to survive. The series mixes action and comedy with ecchi elements.
