>>2183932The Mugen Tenshin think Kasumi is dead (pic related). They're not going to abandon their ancient traditions because one leader wants to break them to protect his sister. Hayate told his clan she was dead, and Ayane agreed to confirm it. Kasumi agreed to banishment and to keep a low profile living a mundane life with an apartment of her own (DOA4 ending). She was moved to the Hayabusa village for protection when they realized MIST was after all the ninjas. Not that it mattered in the end, since they got their hands on the dna of all 4 ninjas anyway.
