|Grade||3rd year in middle school|
|Favorite Food||Okinawan Soba|
|Debut||Yuki Yuna wa Yuusha de Aru - Hanayui no Kirameki|
|Japanese Voice||Yamamoto Nozomi|
She is quiet and composed, with a cool air about her. She is also humble, declining Inubouzaki Fu's thanks after she saved her sister. She is also quite collected, being able to meditate in the middle of multiple waves of vertex attacks.
- She has a few fangirls among the other heroes, including Inubouzaki Itsuki and Iyojima Anzu.
- She appears to be represented by the cherry plum flower.
- She dislikes noisy parties.
- In the timeline, she is probably from the same era as Nogi Wakaba's team, as no other barriers aside from the strengthened Shinju could possibly have resisted the explosion of the first-generation Leo Vertex.
