More Mew Mew Quexque! Or Mew Mew Indigo Milkcap Mushroom.

Except she's not really a Mew Mew, she just thinks she is. She's an alternate vessel of Deep Blue's, meaning she can transform and has powers almost identical to Masaya's when he becomes the Blue Knight, that's why their costumes are almost identical.

This is super early on in her story, so she hasn't customized her costume yet; later on she alters it to be more Mew Mewish.

She and Masaya eventually develop a brother and sister type relationship, and it's pretty cute.
