>>2325190I guess it depends how you would perceive his personality. Some would think he would be an old man with a beard much like Isshin Matoi because. Others could see him as the same age as Ryuuko or simply a male version of her.
Personally I see him as being slightly older than her and while at the same time being her friend but also a father-like figure by giving her advice/ keeping her from doing irrational things.
As for his skin color, he could either be very pale or very dark.
