Desperate Struggle Under the Moonlit Night, the Mysterious Assassin and Zanpakuto

Ichigo repeatedly asks Kenryuu and Enryuu why Lurichiyo is in the real world, and they refuse to answer him. That evening, an assassin arrives at Lurichiyo's home. The assassin uses a weapon with a mirror that reflects the moonlight to stun Ichigo, and nearly kills him. Ichigo uses his sword to reflect the moonlight against the assassin on his second try, and rather than be questioned, the assassin allows himself to be killed when Ichigo uses his Getsuga Tenshou. Afterward, Kenryuu reveals that Lurichiyo is the heir to the noble Kasumiouji clan. He further explains that Gyoukaku Kumoi, one of caretakers serving the Kasumiouji clan, has been attempting to take control of the clan by killing Lurichiyo. Under pressure from Rukia, Ichigo agrees to protect Lurichiyo.
