Aika is super autistic and does stupid and weird stuff. She's slightly nonverbal and can't talk very much. She only speaks in third person", a name she gave her stuffed bear. Aika is also shown to have a playful personality toward her cousins and is overall a very sweet and harmless girl. However, she has sensory overload. If she gets overwhelmed or uncomfortable, she goes on a temper tantrum. She also doesn't like to be touched and bites those as a defense mechanism.
