>>107700981Amanogawa Shiina debuted on July 10, 2022. Her first outfit (crab hoodie) debuted on January 14, 2024, which is a little under two years ago. Her second official outfit debuted yesterday, coming out to about one outfit roughly every 2 years. This is rather slow and only appears frequent if you forget it's been almost 4 years.
The crab hoodie was more of a joke outfit, but it was made with her 2.0 rig and it took months for her original outfit to be upgraded, trapping her with it for a long time. The banana hoodie was a personal project she paid for, and similarly made use of the new new rigging, trapping her in that for a while too.
