Rika is a kind, caring, bright, strong-willed and charismatic person on the outside that is described by the RFA members. She is said to care deeply for others and wanted to help them achieve happiness, which is the sole reason for her creating the RFA and she is also capable of inviting many people to her parties, mainly due to her great influence on others.

Unknown to most, Rika is severely mentally ill as she struggles with depression, anxiety, paranoia and (paranoia induced) delusions, which causes her to lose herself as she does things she never would've done when she had a clear mind. She tries her best to hide this from all except V, the one she trusts most.

As time goes on, her mental condition worsens, only to be intensified by the death of her dog, which she blames herself for. She falls deeply into the delusion that she's a savior, and has to rescue everyone from the pain and sins of this world. Becoming more and more out of touch with reality, this delusion drives her to do extremely harmful things, even to the people she cares about.
