Synthesized from 11 Yomimono stories · updated 1d ago

Houshou Marine's current standing turns on a medical decision. On October 19, 2026, hololive production announced she would withdraw from hololive RECORDS MUSIC STAGE 2027, the two-day live at K Arena Yokohama on January 9 and 10, 2027. Cover Corp. cited treatment for vocal cord nodules. The agency said repeated discussions with her led to the conclusion that she could not perform in top condition. Tsunomaki Watame will appear on DAY2, joining Shirakami Fubuki, Kobo Kanaeru and FLOW GLOW. DAY1 stays as announced with AZKi, Sakura Miko, Hakos Baelz and ReGLOSS. Marine posted an apology on her official X account and said she will recover for the next stage.

The withdrawal is the first break in a run of peripheral activity. Through the summer and early fall of 2026 she appeared in the hololive IF prize figure line from BANDAI SPIRITS, paired with the Crossbone Gundam X1 and scheduled for crane games in February 2027. A RG Crossbone Gundam X1 [Houshou Marine Ver.] was displayed at TOKYO TOY SHOW 2026. VTee opened made-to-order pre-orders for a varsity jacket tied to her 2024 song "Ghost Ship Battle" from September 12 to October 3, 2026, with delivery scheduled for late January to around March 2027. A HoloCa card drawn by Kentaro Yabuki ran in the V Jump October issue, and she is one of 37 talents in Hololive Mahjong -Holojan-, scheduled for release within 2026.

On the music side, her four-track EP 'New World Carnival' was released on September 30, 2026, including "BooooM!!!", the ending theme for 'Magilumiere Co. Ltd.' Season 2. The RECORDS MUSIC STAGE appearance would have followed that release. Instead, the label's first real live proceeds with Watame on DAY2.
