Sayuri

Sayuri is an adorable little blonde girl who showed up out of the blue the day that Zero appeared, innocently asking Katana what he was going to call 'him'.

Biography
For whatever reason, this child, armed with a pink coat, a bunny plushie and a big smile, refused to go away, following the not-so-welcoming boy Katana wherever he went with the claim that she is his "friend". Sayuri seems to seek out others who surround Katana, searching for more friends for him, asking Aiko Mary Harmony and even Takumi Kisaragi if they are friends of his when she runs across them in the junk yard. She always seems to know more than she says, giving nothing but an innocent giggle when asked why she doesn’t go home and where her parents are.

After having her around and for some reason being unable to hurt her, no matter how she waddles around after him and pesters him, Katana becomes accustomed to her, and finally grows attached to her, to the point that she comes with him everywhere, even answering his job phone for him to take messages. She reminds him constantly that he likes Hajiki Sanada, and that they should be friends. He purposely goes out of his way to save her from harm, but why, he doesn't know at first. The truth is that she is a Techode, created from the same Gad that Zero came from, from the part of Katana that remembers his childhood, and in particular, a childhood friend that was very dear to him.

Sayuri is quite possibly the only person or creature Katana has ever truly and completely loved since the day he lost his memory, if only because she is the part of him that remembers, and the proof that he is, at heart, just a lonely little boy. Sayuri is very loyal to Katana, as she was created by him inadvertently. Like all the Techodes, she disappears when he no longer needs her, and learns to function on his own.
