A semi Japanese, semi female name. Koyukis are usually hella short and quirky. They can be described as a grandma (not as an insult, but because the have an aged soul). Koyukis are hidden behind a solid brick wall (much like the titans in Attack On Titans).
"Hey who's that girl who's sipping tea and knitting in the corner?"
"Oh that's a Koyuki! She's very fun once you get past her brick wall!"
