Hitomi's big brother is somehow starting to become my favorite supporting character.
He dominates every shot he's in, even when he isn't saying anything.
He is playing the part of the reliable older brother 24/7, and you can tell he loves every second of it.
Like the kind of guy who will take his sister and her friends to a restaurant,and won't even complain if one of them gets a meal that's way more expensive than everyone else, because he's just that laid back. Then again, he comes from a family of gluttons, so that specific scenario is pretty unlikely, but that same kind of energy.
His straight posture and firm but cheery face always just screams "Hitomi, I am gonna support the FUCK out of your relationship" at all times, even when he's clearly just dicking around.
