Rikka Hiiragi
Appearance: She seems to show 40% of her bare skin to probably show the pureness of her. There are six sun-like orbs on her back which resemble an image of a “sun” on Hotaru's egg. Some of her clothing resembles Hotaru's, and she wears orange hair bands on her hair.
Abilities: As Pure Feeling, she can perform Open Heart with Amulet Diamond; which doubles the power to restoring broken X-Eggs.
