I'm Yuna Shizuma, a member of GUTS-Select. Being the daughter of Mitsukuni Shizuma, the founder of the Sizuma Foundation, and one of the founding members of the TPU, I have received a privileged education from a young age. I contribute to the expert team in a myriad of ways in their fight against monster attacks.

Initially unknown to me, I house the dormant spirit of Yuzare inside her body.
