From Hokuto no Gun:
This brief story follows the reincarnation of the Emishi warrior Aterui, who turns out to be a guardian deity protecting the mysterious power source called the Dragon from the gods of destruction, into the body of mild-mannered archaeologist and professor, Kogami Ryuichi. This short volume is packed with action, violence, and even political satire.
