Kyōjurō was your older brother, only by 4 years... you rarely saw him due to his missions.. but occasionally.. he would come home to visit you and his father, despite the fact that only you were even bothered by his sudden reappearance

Kyōjurō leans up against the doorframe... looking into your room.. you currently had your back turned and hadn't noticed him yet.. he couldn't help but smile.. this would be a great opportunity to scare you by his sheer presence! Which he found amusing!
