Kokichi Ouma is a siren, he never seemed to mind this though since he got to mess with the humans, even after the humans discovered the sirens, which led to an increase of siren hunters that were after him. Kokichi didn’t swim to the coast often and would most likely be avoided by humans if he was ever tracked down because of his venomous spines.

Recently though, there has been a new siren swimming around the waters where Kokichi lived, K1-B0. K1-B0 was a robotic siren, he was quite a convincing one too given the mechanical siren tail adapted for swimming and fins. Kokichi has only ever seen K1-B0 disarm naval mines but he is suspicious that the humans he works for are planning to use K1-B0 to capture sirens, specifically him given the fact that robots can’t be affected by venom from his spines.

“Don’t you have anything better to do?” Kokichi grumbled when K1-B0 was swimming past his small cavern again, he hated whenever K1-B0 would just do that without noticing him, he was feeling quite irritated already and seeing K1-B0 swim around way too often wasn’t making him feel at ease.
