Under the background of the rise of a new generation of information technology such as artificial intelligence, big data and the metaverse, the explicit form of youth subculture has begun to have a new meaning. As a popular youth subculture, virtual youtubers (vtubers)reflect the young generation's reflection on reality and the pursuit of self-realization. This article takes the fan group of the vtuber as the research object. With the help of the theoretical perspective of identity, it adopts the research method of in-depth interviews to deeply understand the self-positioning and specific practice of vtuber fans, and then analyzes the construction path of fan identity from the aspects of individual identity and group identity. The study found that this identity as a vtuber fan is actually another layer of self built by young people in cyberspace, which fans can realize the reorganization of their identity and the expression of their true self. At the same time, by establishing a para-social relationship, fans have completed the purchase of emotional services from vtubers, filling their emotional vacancy in real life. Finally, it reveals the reality and social mentality of the young group hidden behind this subcultural phenomenon.
