Chroniko

She sells her body (literally) so that the money can support her family and hopes that someday her family will become wealthy enough to buy her a new body in the future; however, she is killed by a corrupt doctor (by simply releasing her mind from storage), and her body is sold anyway. Before her body is taken by the buyer, Hyo-Hyo places Kaiba's mind inside her body, and Kaiba uses this disguise to avoid capture and get back aboard Neuron.
