12-episode anime adaptation ended this week

The 12th compiled volume of Shinjirō's Taboo Tattoo manga is announcing on Friday that the 13th volume will be the last.

Shinjirō launched the manga in Comic Alive magazine from Kadokawa's Media Factory imprint in November 2009. Yen Press will publish the fourth volume in North America in October, and it describes the story:

By all accounts, middle schooler Seigi is pretty unremarkable except for his martial arts prowess and a desire to protect the weak. But when his good intentions are put to the test by saving an old homeless man from some street thugs, the mysterious man shows his gratitude by...burning a tattoo onto Seigi's palm?! It turns out, the tattoo is a powerful secret weapon that everyone--including a formidable girl with a tattoo of her own--is after. With his life on the line and his martial arts skills alone no match against super-powered foes, will Seigi be able to unlock the latent potential of his tattoo and live to fight another day?!

The manga inspired a 12-episode anime adaptation that premiered in July and ended this week. Takashi Watanabe directed the series at J.C. Staff.

Shinjirō is also drawing manga adaptation of Gen Urobuchi and Type-Moon's Fate/Zero light novel series. Dark Horse Comics will publish the third volume in English in November.
