However, her kind-hearted nature often leads her to help people in need, even though she intends to cause mischief.

She shares a close friendship with fellow Nijisanji members Belmond Banderas and Ars Almal, frequently collaborating with them. Roa's popular gesture of thanking fans with a wink when receiving donations has endeared her to her audience.
