U-N-L-O-C-K:Kuroki Yui

Yui is a submissive person.She is very shy towards other people and rarely speaks.She is very respectful towards other people,whether they are older or not.Finds refusing someone very hard so she sometimes ends up being used by other people.Because of the way she was brought Yui is ver well mannered and somewhat of a neat freak.After she gets to know someone she will start to warm up to them and becomes more talkative.She will come as kind and caring to that person or people.With her warming up to another person she may show some of her real personality's traits and may become somewhat of a tomboy.Yui is somewhat less shy towards female students so she tends to warm up faster whereas she may be so shy towards a male that she will end up running away.Has a tendency of saying "I'm sorry." or "Please forgive me." whether she has done something wrong or not.

Yui was born in Miyazaki Prefecture as the sixth child of the Kuroki family.Despite being the youngest out of the six children she was the heir of the family due to their family's tradition that stated the oldest daughter would become the heir.As a child she was mostly taken care of by her older brothers because her parents were travelling abroad or busy with work.Her parents felt somewhat guilty because they couldn't be there for her so they spoiled her quiet a lot.From a young age she started lessons that ranged from etiquette to music,learning to play many instruments.As she grew,Yui's parents started acting very strict with Yui,demanding her to learn as much as possible.Because they wanted to keep Yui safe she wasn't sent to school like normal kids but was brought tutors at home so she never really developed any socializing skills and became pretty shy towards other people her age and secluded not talking to anyone about her problems.

The only people who were with her were older brothers so of course some of their habits were caught by her.Whenever her parents weren't in the city her older brothers sometimes took her out with them teaching young Yui about their hobbies and such.Not all of them were friendly with Yui as they felt she didn't deserve to be the heir of the family but understood how sad she was.She got most attached to her youngest older brother Makoto,who was part of a rock band at that time,and Kyouya,the oldest brother,who was a soccer player.Makoto would always take Yui to his bands rehearsal sessions and even taught her how to play a guitar and Kyouya taught her the basic rules of soccer and even taught Yui how to play a little.Because of this Yui started liking soccer and rock music but realized she couldn't tell her parents as they would be mad,however Yui was extremely happy to at last have someone who would look after her and teach her new things.Some of their habits rubbed off Yui to as she started sometimes addressing herself in ways her older brothers would or being more daring and somewhat demanding herself.

As Yui grew even more because of the age difference most of her brothers left to college or went to study abroad leaving her alone.Because of they left Yui reversed back to her shy and secluded self.The next years where a pain for her as she was left all alone,feeling betrayed.From time to time her brothers would still visit her but it wasn't enough to fill the hole in her heart.On her 13th birthday Yui decided to fake the fact that she was going through a rebel phase and started acting like she really wanted to be.She played loud music in her room and started playing with the boys in the neighborhood.Her parents decided to send Yui to Seiso Academy on the Seiton islands near Honshu as they thought she would go back to her old self.When she arrived to Seiso Academy Yui reverted to her old shy self as she felt she couldn't show her real self before she got to know some people.She is still getting used with the crowds of students and going to school for the first time.
