- Hollow Mask: Rikka's Hollow Mask is her main use of weaponry along with her Zanpaktou.
- Hollow Combat: When Rikka fights with his mask on his fighting style becomes more playful and acrobatic. She will usually quickly strike her opponent quickly and from the sky as she flips through the air.
- Power Augmentation: While wearing the mask, Rikka's hollow powers supplement her Ninja and Shinigami powers, giving her a vast increase in both strength and speed. The explanation for this is that since Hollows boost their natural abilities by obtaining spirit power around them, either by absorbing it in its ambient form or from another living being, Rikka attains power from two separate sources: that from herself (drawn using her Ninja and Shinigami energy), and that from her immediate environment (drawn with the help of her Hollow powers), allowing her to draw power from both sides. It could even be suggested that the Hollow mask allows Rikka to recapture the energy she constantly leaks into the environment, making her more efficient.
- Time Limit:: It hasnt been exactly shown how long she can use his mask, however, it has been speculated she can keep it on for several hours without tiring.
- Cero: Rikka has shown to utilize a Cero blast but is kinda of inexperienced at it. Her personal cero is pink-colored.
She was born in Yukigakure and lived as an orphan until she met Byakko Kurohitsugi whom she had a crush on and vice-versa. They met with three other and started the Ashiki and lived together as a family. She, during this time, learned to harness her Inner Hollow's power.
She first appears together with the Ashiki when Seireitou Hyuga comes to learn to supress his inner hollow. During this time, it was revealed that, her personality has been that of flirtatous, as seen when she flirted with Seireitou constantly during his training.
After the war, Rikka marries Byakko and lives somewhere in the Land of Lightning, in a non-ninja village.
