Yui 01


Yui is a girl who's easily distracted by cute things. She's a crybaby but cheers up easily if she gets some sweets. She eats a lot of sweets but she does not gain any weight as she herself says. In many ways some may say she's a child, and making sure she practices is a problem. When Yui takes good care of something she sleeps with it. When she wants to remember something she forgets everything else. Yui's energy seems to come from cake.

She does not get good grades in school and is easily distracted by trivialities. Yui is clumsy and easily spaces out most of the time. She has her younger sister Ui to take care of her and keep herself in line. She has a very easy-going nature, but has incredible concentration when hyped, though this is only limited to one subject at a time. She will totally neglect any other things in the process, to the point of forgetting anything she has learned beforehand. Despite all her flaws, Yui is still a fundamentally good-hearted girl who openly expresses love with hugs and adorable nicknames (most notably "Azu-nyan" for Azusa), and once devoted to something she is loyal to a fault, and can display near-genius levels of competenece to the subject of devotion, as shown by her perfect score in the makeup exams to return to the band. She has perfect pitch and is the group's main vocalist, although she is known to forget her lyrics in mid-performance, as well as overdoing things, making her unable to perform sometimes.
