Taboo Tattoo

Seigi is an ordinary middle schooler with a strong sense of justice and solid martial arts skills, always ready to stand up for someone being bullied. After he rescues an elderly homeless man from a group of thugs, his good deed is repaid in an unexpected way: a strange tattoo is seared into the palm of his hand.

The mark isn’t just ink—it’s a hidden weapon coveted by dangerous forces, including a formidable girl who bears a tattoo of her own. Thrust into battles against opponents with powers far beyond what training alone can handle, Seigi must uncover what his tattoo can really do if he hopes to survive what’s coming.
