Sumitani Yumi (澄谷 夕美) is a Taimanin and secret idol called "YUMI-SONA". Designed by Kagami Hirotaka. Introduced in Taimanin RPGX on 30 August 2024.
A shy girl who normally does not stand out too much, typically a bookworm type and loner. She often calls herself "pile bug, slug" or other such terms when comparing herself to others that she views as better. Lacking confidence for most of her life, even though she belongs to a prestigious clan, she has only recently begun to work on herself more, but is not yet willing to share it with everyone.
Yomi awakened to her Ninja Art after a conversation, which allowed her to break out of her shell and take on different personality types, preferring the very outgoing one. She wishes to grow more confident with that but keeps this ability and second life she made as an idol a secret.
When using her Ninja Art, she changes herself to a more outgoing and flashy personality.
