Season 9, Episode 170 - "Desperate Struggle Under the Moonlit Night, the Mysterious Assassin and Zanpakuto"
14 May, 2008
Ichigo repeatably asks Kenryuu and Enryuu why Lurichiyo is in the real world, and they refuse to answer him. That evening, one of Kumoi's assassins arrives at Lurichiyo's house. 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 tenshō. Afterwards, Kenryuu reveals that Lurichiyo is the heir to the noble Kasumi-Ooji clan, and the clan's caretaker, Kumoi, has been attempting to take control of the clan by killing Lurichiyo. Under pressure from Rukia, Ichigo agrees to protect Lurichiyo.
