Koi isn't his name, but people call him that for lack of a better name. He doesn't talk about himself much, or at all, so his name is a mystery
He was trained to be a spy from a young age, which is probably why he's so quiet, and why his clothes are dark. he also dyed his hair black to make it blend into his surroundings better, but his roots are growing out lol
his eyes are very peculiar, the pupils seem to have some kind of glowing substance inside them, which is also what makes the iris so bright
the spies he works with all have a dark red safety pin on their chest, signifying that they are part of that organization i guess?? idk
he also has a little knife that he got when he joined the spies, which has a sentiment to it
lmk what yall think of this little boy, i wrote all this on my computer bc it was too much for my stylus lol
hope you enjoy him! btw he is in the same universe(?) as Ekko (i changed the spelling, is it cooler?)
