Volume 10, Tattoo on the Sky, finds our heroes as guests of the slightly crazy explosives expert Shiba Kuukaku--Ichigo, Yoruichi-san and company need her help breaking and entering into Seireitei. Kuukaku's brother Ganjuu, with whom Ichigo tangled in the previous volume, is hanging around too, with predictable (and amusing) consequences as far as Ichigo's temper goes. Although the group succeeds in turning themselves into a spirit-force cannonball, once they arrive in Seireitei, the fun is just getting started. Meanwhile, meetings of the captains and vice-captains of the 13 squads are held, and Ichimaru Gin is called on the carpet to answer for his unapproved actions regarding the intruders.
