The Intoku Family Clan is special for having members who control the power of aura, which gives them superhuman abilities. Thus, part of their duty is to help those who are weak and vulnerable.
One day, a simple merchant called Yamamoto reaches to them to consult for an escort, in order to safely return to his village. It is decided that none other than Morinosuke Intoku, the son of the Family Head Leader, should be his bodyguard.
The mission seems simple at first, but there´re details that Yamamoto has hidden from everyone, and will make the escort not as straightforward as Morinosuke expects.
