Gender: Female Age: Early 20s (She keeps her exact age a secret.) Weight: 4n kg (She says this is a secret too.) She is almost always in cosplay, and she absolutely stays in character when outside. She is an extreme otaku to a near-insane degree. She has long blonde twin-tails and sparkling pink eyes. Honestly, she is quite pretty. She is always cheerful and energetic, occasionally showing an eccentric side.

Gender: Female Age: Early 20s (She keeps her exact age a secret.) Weight: 4n kg (She says this is a secret too.) Star Nova's true everyday self. Unless she is home alone, she rarely takes off her cosplay. Her natural personality is completely different—timid and shy. Accordingly, her speech becomes hesitant, and she says she can't project her voice very well. Apparently, she can't overcome this even with effort. When not in cosplay, she wears glasses and has messy, unkempt long blonde hair. Her overall appearance looks like someone who hasn't showered in a day or two. She says her stomach hurts often, likely due to her eating habits and diet. She is a femcel (a woman who desires romantic or sexual relationships but feels unable to obtain them regardless of her will).
