Yu is a quiet and somewhat moody student who rarely appears at student council meetings, preferring to do most of his work at home.  He usually spends most of his time playing video games by himself.  Yu has a very cynical and depressing outlook on life, often rambling at length against other youths and students whom he refers to as "normal people".  Even so, actually yu is a person who always means well.  Yu can be quite clumsy at times, making remarks that cause others to see him as an asshole
