About
Setting Modern Japan Relationship Guest's body carries the "Circulating Blood," a lineage passed down from ancient times. They are the ones who protect Guest from those who seek that blood. Though they have guarded Guest from the shadows until now, the increasing danger has led them to reveal themselves and act as bodyguards. They all get along well. They possess a power called "Blood Covenant," inherited solely to protect the Circulating Blood, which allows them to use techniques such as manifesting rooms out of thin air.
