Oshiro Mashiro Fan Ends 500-Day Counter After Her Graduation

How does it feel to lose a VTuber you really liked? Today, I’m bringing you a story about a VTuber you probably don’t even know, but this story made me sad. Oshiro Mashiro was a VTuber who was part of the Aogiri High School agency.
She debuted as a VTuber in April 2021 and became one of the most popular VTubers in her agency. Her focus was comedy, and she became known as a “comedian VTuber”.
However, everything good eventually comes to an end (and everything bad seems to last forever). Unfortunately, Oshiro Mashiro faced health problems. She even went on hiatus during 2024, but she was unable to recover, resulting in her graduation in February 2025.

Oshiro Mashiro was retiring as a VTuber because of her health. Fans were devastated, but one of them believed that she would return someday… but 500 days later, that did not happen…
Oshiro Mashiro Fan Ends 500-Day Counter After Her Graduation
After the VTuber’s graduation, a fan created a Twitter account called “Oshiro Mashiro Count Up Bot”, which recorded every day how much time had passed since her graduation, keeping alive the hope of a possible return.

After reaching 500 days since her farewell, the person responsible for the account announced that they would stop the count. In the message posted, they explained that they still held a small hope of seeing Oshiro Mashiro return or finding someone very similar to her. However, after 500 days, they said they imagined Mashiro was now living a normal life and had already become accustomed to this new phase outside of VTuber activities.
The fan also stated that they decided to stop to prevent the account from causing any kind of discomfort for the VTuber herself, saying that they would continue keeping their memories privately.

If you think it only affected him, you are mistaken. This decision moved other people, who thanked him for the effort made throughout all those days. Many commented that following the daily count was a special way to remember the VTuber and expressed gratitude for the dedication of the person behind the profile.
Even after her graduation, Oshiro Mashiro continues to be remembered by part of her community. The story of the fan who maintained a counter for 500 days shows how the relationship between virtual creators and their followers can go beyond simple entertainment, creating bonds and memories that remain even after activities come to an end.
