He would age a bit more faster due to stress I think and starts greying at 26. But he still maintains an elegance that’s reminiscent of his mama….the guidebook mentions him having to eat astronaut food since childhood bc of junko’s neglect (not sure if this carries to the EP timeline) so i dont think he’s having a consistent diet to be on the level of his mom’s planned meals by her management team due to her celeb status .

Though I think he accepts he’ll mostly look like his mom that’s why it hits like a truck when he turns 40 and looks in the mirror and is reminded of Akinari and is like shit… wait….
