Personality

Story
Naoya first appear in Chapter 1 as he open the doors to his brothers while being butt naked in his office. Upon seeing him naked, Souta reprimanded Noaya by calling him a stinky old man. Afterwards, Naoya went towards the table to eat the dinner that Yuuto has cooked for him. When Naoya ask for the ketchup for his omelet, Souta delightfully brought it to him, only to write "pervert" on his omelet with the ketchup.

While eating his dinner, Naoya was confronted by Yuuto who wanted to get a job. Naoya reject his request saying that Yuuta should focus on school instead. And if Yuuta needed more spending money, he just need to wait for the next month income to role in. Hearing Naoya, Yuuto quickly shake his head. He didn't want a job to have more spending money. Instead, Yuuta wanted a job to help with the expense around the house so that Naoya won't have to work so hard. Hearing Yuuto's sincerity, Naoya can't help but feel guilty that he's just been playing around with girls instead of working properly.
