>>108502321Sinon is actually Airi's biological daugther from a teen pregnancy, the entire "Airi-mama" but was started to pre-emptively cover for her slipping up and actually calling her "mom" on stream.
Bibi being her daugter made sense both canines with brown hair with a white stripe. Sinon is just a Korean girl with a siren model, the only reason they would be related is if they were actually related and Airi being in her 30s and Sinon being young makes this entirely possible.
Uruka is also a relation of Sakana, Phase Connect started as a family business.
