OOC: What ages typically mark anything significant for Kurosians? Like, do they begin receiving “significant education” at age 5, or, say, do they enter puberty at age 16? I’ve got a headcanon that they enter a sort of puberty at age 20-ish and it ends about 30’s.

OOC : Pretty much depends on the family. If they’re military based, they can start training as young as three. The orphanages usually branch education out depending on the child and their interests, or if they don’t know what to do, they go to public schools until they decide. Some families allow their children to choose their own paths of education, while more stubborn families will control where their offspring go and what they become. 

Kuros can’t reproduce until they hit anywhere from 25-35 years old, so you’re close! However most won’t actually try out for breeding contracts until they’re past 100 or so, they usually want to make a name for themselves and earn a place before having offspring.
