Kashiwada's Brother

About
Kashiwada's Brother is a side-character of Expressionless Kashiwada-san and Emotional Oota-kun and This Girl Will Express Herself in 100 Days. He is the brother of Kashiwada and his birthday is May 31st.

Appearance
Kashiwada's Brother is often seen wearing a buttoned-up shirt, with a supposedly friendly smile. Although he looks like he's smiling, he is the same as Kashiwada in the way that he always has the same face. How he's feeling can often be seen in his font, and the area surrounding him.

Personality
Kashiwada's Brother seems very friendly, but is extremly over-protective of Kashiwada. He is mainly seen acting aggresive towards Oota, when he thought he was her boyfriend or bully. He is however, very calm otherwise; even offering Oota to stay. Whether this was a ploy to find out more, or just out to be friendly is unknown.
