Hiiragi, Rikka

She is a female second-grade elementary school student who has just transferred to Seiyo Academy. She possesses a spirited personality and is easily distracted whenever someone speaks to her. She is very kind and caring toward helpless creatures, for instance, watering a plant on the sidewalk or saving a kitten from a tree. Ever since she first met Amu Hinamori and the Guardians, her dream goal has been to become a Guardian herself.
Rikka has the rare ability to see Shugo Charas and to communicate with X-Eggs without having her own Heart's Egg.

When Hotaru Character Transforms with Rikka, they become "Pure Feeling". She "slightly" resembles "Amulet Diamond" by the yellow clothing and hair style.
* 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's Egg.[/spoiler]
