Silhouette of Shigumano's new outfit

On March 14th, Shigumano posted an image on X (formerly Twitter) showing the silhouette of the next costume for her Vtuber model!

The date for the reveal is most likely April 9th.
This day has a special meaning due to how "4" and "9" can be pronounced as "Shigu". For this reason it is often a day associated with announcement or unveiling since Shigumano has debuted!
As it has been the case since her debut, this model is also made by Shigumano herself!
