Sayoko is only mentioned in the GDWO manga once because after her mate Izou rescues Weed's daughter Bellatrix from a Kurohabaki clan agent. Masashige, a high ranking Kurohabaki clan member, manages to find where her and Izou live and then he along with several other clan members murder her and her pups immediately. After Sayoko is not mentioned again.
