This Unnamed Girl is a member of a distinguished family in the Kuremisago Clan.
She was present along side her partner behind Kajima Satomi as they are present as he leads the YOMI and Hachiou disciples to battle. She was later seen with Kajima as he leads Miu, Kenichi and Niijima into the base. After Kajima engages Kenichi in battle, she and her partner fight Miu.
Miu is having trouble fending off her opponents, whose attacks seem to be increasing in ferocity. she finds an opening and attacks them with Fuurinji Kouhou Yoku. Miu's attack is cut short as her opponents are able to grab her leg and stop her rotation, and she is lifted off the ground and left vulnerable; she notices that the Kuremisago disciples have unleashed their Dou ki.
With Miu and Kenichi wishing to help Niijima, their battle progresses towards Niijima's location. Once they arrive at Siaga's location, Miu manages to defeat her opponents thanks to her mastery of her dou ki, though she is worn out from the fighting.
