Hololive Vtuber Mori Calliope Takes Break for Health Reasons

Following her solo concert Grimoire and appearances at Hololive Super Expo 2025 and Hololive 6th Fes, Vtuber Mori Calliope announced she’s taking a break for health reasons. She confirmed on social media that she’s seen a doctor, and she also noted she will keep people updated on her progress.

Mori first mentioned feeling unwell online on March 10, 2025. This was one day after the events and concerts in Chiba, Japan. At the time, she reported that she would take some time to recover after experiencing “a fever and chills.” She then noted she visited a doctor on March 11, 2025, who blamed it on the shift from winter to spring. She also mentioned an additional appointment later this week. 

Here’s the full statement Hololive Vtuber Mori Calliope made regarding her health and her temporary break while she recovers. Further updates will be shared via her official account.

In addition to the concert and performances at Hololive 6th Fes, Mori released a new song. She collaborated with Persona series composer Shoji Meguro and Lotus Juice, who worked on Persona 3 Reload, to create the song “Seeing Stars.” The song is also available to buy via storefronts like Amazon.

Hololive Vtuber Mori Calliope is temporarily taking some time off for health reasons while she recovers, and she’ll update on her return in the near future.
