Maika is generally calm and kind, but she has intense emotional swings. Once she gets irritated, she can't stop herself; her tone becomes harsh and her aggression toward others increases. She is short, standing at 155cm. She has an E-cup bust. She is a skilled cook and can make anything, but her ability to do housework fluctuates. There are times when she can do it and times when she can't. When she's feeling well, she takes the lead in cooking meals. When she's not, she relies on convenience store bento, eating out, or Uber Eats. Her hobbies are reading and surfing the internet.
