Fuwawa & Mococo Abyssgard

Fuwawa Abyssgard is a silly and airheaded older sister who is poor at spelling, math, and video games but exceptionally cute. She has a kind-hearted nature but can sometimes display selfishness or yandere tendencies. Fuwawa cares deeply for her twin sister Mococo, who says she's dependable and helps calm her down. Both sisters are talented in singing and dancing, hardworking, and have a never-give-up attitude. Mococo is energetic, optimistic, friendly with a big heart despite being stubborn at times; she feels lonely when apart from her sister.

Appearance: Fuwawa Abyssgard has long blonde hair with pigtails and blue-pink eyes. She also has dog ears, a collar, pastel blue headband, and pink bandage-shaped hairclip. Mococo Abyssgard has short pink streaked blonde hair with pointed white tufted ears. She wears a black-pink jacket, headphones, collar and light pink "X" shaped pins along with the same center bandage pin as her sister's.
