The Umamusume: Pretty Derby concert tour planned to visit California, but U.S. immigration authorities denied visas to the Japanese cast and staff, forcing cancellation. The decision disappointed fans who had anticipated the event. Cosplayer Clara Tan, interested in the franchise, chose to travel to California anyway and attended related activities, cosplaying as the character Super Creek.
When Tan prepared to return home on October 26, flying to Rochester, New York, she expected to travel without incident. That expectation ended at the airport terminal at midnight.
The Arrest at the Terminal
Four Immigration and Customs Enforcement agents called out Tan’s name as she exited the terminal with her collected luggage. They announced they had a warrant for her arrest. Tan asked to see it and requested identification. “We can show it to you in the car,” one agent replied. “Just come peacefully.”
As Tan reached for her phone to call for help, all four agents moved toward her at once. Her phone went flying from her hands, and she was tackled to the ground. She heard what she describes as a severe crack from her foot. This injury would later require hospital evaluation. She was handcuffed behind her back.
She was placed in an unmarked SUV. One agent allegedly told her: “This could all have been avoided if you’d just come quietly.” She was taken to Batavia Detention Center.
Inside Batavia: The Warrant and Detention
The Warrant’s Problems
After 14 hours in custody, Tan finally saw the arrest warrant. She claims it was not signed by a judge. The document contained factually incorrect information. It listed her entry date into the United States as “unknown” and her point of entry as “unknown.” In reality, Tan had legal documentation proving her entry and extended lawful presence. She attended the American Musical and Dramatic Academy from June 19, 2019 through October 31, 2020. This period of full-time enrollment and graduation constituted lawful residence. She possessed her passport and academy documents. The warrant did acknowledge that she is Singaporean and not a U.S. national, yet it made no mention of her educational enrollment or years of lawful residence.
Denied Medical Care and Phone Access
When Tan requested a phone call, she claims staff told her to “shut the fuck up and go to sleep.” When she asked for a nurse to address the pain in her foot, she says she received the same response: denial and demands for silence. The pain from her likely-fractured foot prevented real sleep. She spent the night on rough blankets in a small, metal room.
Gender Housing and the Medical Intervention
The next morning, additional prisoners arrived. All were men. Tan asked if gender-appropriate housing arrangements existed. Staff responded that she was told to stop speaking. She mentioned that she is trans and asked about separate gender housing.
At one point, according to Tan, a guard responded to her inquiries with a crude question about her anatomy. Tan eventually persisted in requesting medical attention. Two medical staff members examined her, and both validated her claims about pain and injury. According to Tan, this medical confirmation triggered a visible change in staff response.
Rather than detain her until a court hearing, the facility released her with an electronic ankle monitor. She was informed that Batavia houses “pre-op trans women,” but she claims the guard told her “not anybody with a vagina.” This distinction meant the facility did not consider her an appropriate case for ongoing detention.
The Injury and Hospital
Tan went directly to Strong Memorial Hospital’s emergency room in Rochester. She was 90 percent certain her left foot was fractured. From the hospital, she posted her 18-hour detention experience to Facebook, detailing every stage of the arrest, confinement, and medical neglect.
The Broader Context
The cancellation of the Umamusume event reflects a widening pattern of visa denials affecting Japanese performers. Stricter immigration policies have created barriers preventing international artists from entering the country. Some community members, like Tan, travelled to California anyway in hopes of celebrating or connecting with others.
Umamusume: Pretty Derby, a mobile game developed by Cygames, maintains a dedicated global fanbase and regularly stages concert tours and live events. These gatherings serve as gathering spaces for fans. When tour stops are cancelled and attendees face enforcement consequences, the disruption extends beyond a single event to affect community spaces and shared experiences.
Questions About Documentation and Procedure
Tan’s detention raises questions about accuracy in immigration enforcement documentation. A warrant used to arrest and hold someone contained demonstrably false information. It claimed unknown entry and point of entry despite legal documentation of entry and years of documented presence. The treatment she received regarding medical care, phone access, and housing also deviated from standard detention procedures.
Her story illustrates how distant policy decisions become immediate, personal reality. She is a Singaporean national with lawful basis for residence through educational enrollment. She had years of documented presence on American soil. Yet these facts were apparently absent from the warrant used to arrest, detain, and interrogate her. In her closing remarks, she asked others attending gaming and entertainment events to picture her face when considering immigration policy. She urged them to recognize the concrete human consequences behind abstract political debates.
