Cibo (シボ, Shibo) is a major character in the Blame! manga, accompanying Killy in his quest for the Net Terminal Gene. She was the head scientist of the Bio-Electric Corporation.
She is a brilliant and calm person, with her way of being very minimalist, even a little mysterious at times. From the different situations she gets involved in it can be seen that she has a good heart. She has a subtle connection with the Netsphere, but even if she were able to make a direct connection to it, the Safeguard would be invoked immediately, due to her not possessing the Net Terminal Gene.
Cibo seems to feel comfortable with Killy, who also has a calm and minimalistic style. She is still a more talkative person than him. They both seems to have no feelings for each other in their relationship, so it is practically impossible to judge how they relate to each other. At all times they behave as only companions on a journey together.
Due to her capabilities in transferring her consciousness into new bodies, Cibo's appearance changes frequently throughout the series. We first see her as a young, very tall woman with a petite build and short black hair (though its never confirmed this was her original form). Her uniform, different from that of the rest of the scientists, may have marked her status as the head scientist.
