The Anime Lad
Seigi is a young martial artist who steps in when thugs attack an older man. The rescued stranger gives him an object that marks his palm with a tattoo. It is actually a special weapon capable of supernatural effects. When American agent Ijii arrives to recover such tattoos, Seigi’s helpful impulse expands into a cross-national conspiracy with inadequate advance notice.

Gigguku
Seigi does one decent thing on the street and walks away with a supernatural weapon printed on his palm. The tattoo can warp space and immediately makes ordinary martial arts feel much less ordinary. Then agent Ijii appears with a mission to recover these marks. A simple rescue becomes the entrance to action operating far beyond one neighborhood.
Father's Basement
Giving a martial artist a space-warping tattoo is not a subtle opening, and the larger conspiracy arrives just as loudly. The combination is efficient. Seigi rescues a stranger and receives a supernatural weapon before meeting the American agent assigned to recover tattoos like his. His decision to help turns an unexplained gift into a conflict he can no longer treat as private.
