Not much is known about his personality. Masaru is shown to be a laid-back person. However, he has a short temper and has a tendency of shouting to others.
Sweet Room Arc
Masaru was first seen in the toilet along with his friends. Shortly after, Nozomi Kaminashi entered the toilet. But soon, she screamed and ran into Sayaka Miyata upon seeing male students at Setouchi. Sayaka explained to Nozomi that male students were there to study to become Keijo Engineers. Nozomi was shocked since she thought that Setouchi was an all-girls school. He approached Nozomi and mumbled that she didn't apologize for seeing him while peeing.
- (To Nozomi Kaminashi) "It's all because of people like you. Everyone thinks that Keijo is nothing but rude idiots."
