This study examines the impact of VTubers, with a focus on Kaku Kamu, in enhancing student engagement during campus activities at National Taichung University of Education, Taiwan. The research involved an online survey of 300 students and follow-up interviews with 15 participants, analysing the influence of Kaku Kamu’s presence at the 2024 freshman orientation, which featured both online and offline components. The event demonstrated significant success, characterised by high levels of student participation and positive feedback from both attendees and university staff. Key findings reveal that interactive content, such as Q&A sessions and musical performances, substantially increased student interest, with online activities being particularly appreciated for their flexibility. Offline components, including gamified challenges like stamp-collecting, further enhanced engagement by offering tangible and immersive experiences. Participation levels were influenced by factors such as event timing, cost, and opportunities for direct interaction with the VTuber. Additionally, students expressed a strong preference for integrating more immersive technologies, such as augmented reality (AR), to strengthen the connection between digital and physical spaces. This study concludes that VTubers like Kaku Kamu present universities with a novel and effective strategy for bridging digital and physical realms, enriching student experiences, and fostering greater campus engagement. The successful implementation of Kaku Kamu’s events underscores the potential for VTubers to serve as digital ambassadors, enhancing campus identity and promoting student involvement through hybrid event models.
