The girl (called 纱利雅) in rumor living with 副島雄一 does not seem to be the No.4 kizuna Ai ,纱利雅 seems to be just an employee of Activ8,but the No.4 is belonging to the Netease company.Chinese fans hate 纱利雅 not because she is the No.4 but she mocked the original Ai-chan fans as an employee of Activ8 . By the way,it is not too rigorous to prove whether two people live together or not just with 2 cat pictures.Such accusations are too vicious for a girl.
