Personality
Erika is a feminine young girl who loves fashion and dreams of becoming a fashion designer.

She is able to tell their feelings or moods using the color therapy she is going through. She is also a very fast learner and is fairly cheerful and energetic- although she also has lazy tendencies.

However, Erika is also childish and immature, sometimes coming off as selfish. She can be impatient if things don't move fast enough, and is nosy and the type to say what is on her mind. This brash personality causes her to come off as abrasive towards more shy or reserved types, but at the same time she can become more mindful towards them and will always be there to comfort them should they need it. She cares deeply for her friends, even if she struggles to express it in a way that doesn't cause them further anxiety.

Despite their similarities and shared interests, Erika is very jealous of Momoka and often ignores or pushes her away as her sister attempts to help her or make suggestions. She wishes to surpass Momoka some day and would rather do it on her own then ask her for help. But over time she gradually begins to open up to her sister and grows less hostile.
