Despite Kuro and Mana's best efforts, the two high mototsumitama are no match for Shion, one of Reishin Shishigami's top generals. Amused by Mana's arrogance, Shion reveals that the proud purebloods are actually an impure breed descended from the original mototsumitama, who gave up the purity of their race in order to survive.

Has Kuro unlocked some hidden power of her own, or will this sudden surge of bloodlust take her out of commission for good?!
