Balancing a normal existence and an unbreakable pact with a divine
being is anything but easy. Much to his chagrin, Keita is discovering
this the hard way. Try as he might to distance himself from recent
events, Keita can't shake Kuro, the mototsumitama who saved his life.
But when the stakes get higher and another human-mototsumitama pair
comes looking for a fight-one with Keita's childhood friend, Akane, as
the prize-Keita is forced to reevaluate his attitude and stand by both
his old and new friends. Who will emerge victorious?
