Everything was extremely perfect until i saw a boy in my girls only party. Actually, I mistook her for a boy and kicked her out out of the party, all because she is a beta-chester.
Your disguise is perfect, Kaito Kid, but you made one deadly mistake,... assumminq Sera was a girl just because other tomboy attitude and she being a beta-chester.

Get the Chesteringmug. Chester is a humble and introverted guy and doesn't like people.
But he has a big and kind heart.
He is cold, he doesn't know how to express his emotions well but he manages to hold a grudge. He cares a lot about the judgments of others, in fact he never manages to be himself 100%. While he may seem cold, reserved, emotionless and indifferent, in reality it might just be him armor of him or maybe he's really IDGAF of the people. He seems to trust people but in reality he can't be comfortable with anyone. He always seems so mysterious, you will never be able to understand what is going on in his head. He is always chill, but when he gets angry (he rarely gets pissed) he can be uncontrollable.
