Riontaun has officially left WACK, the agency that managed her throughout her time with girl group ASP. The member announced the news on social media on May 31, sharing that she's moving forward toward new opportunities.

"I haven't posted in a while," Riontaun wrote on her SNS update. "I've decided to leave WACK. As I said before, I'm heading toward something exciting. I feel like I can do anything now."

Riontaun was part of ASP's final lineup, which disbanded on May 4 after five years of activity. The group's last performance took place at Tokyo's Spotify O-WEST venue, concluding their farewell tour "This is ASP's final tour." ASP had become known for its rotating membership over the years, with Riontaun among the five members who saw the group through to its end, alongside Namaenai, the Matilda Twins, the Wonka Twins, and Ikou Mugenno Kanata.

ASP's journey began in 2021 when members were unveiled during WACK's joint audition. The group went on to release their debut album "ANAL SEX PENiS" in May 2021 and achieved major label status through Avex Trax in August of that year. Over their existence, they built a dedicated fanbase through consistent live performances and even ventured internationally with their 2025 UK tour.

With ASP's disbandment, members have moved in different directions. Social media accounts associated with other group members have already been deleted, though Riontaun's departure announcement suggests she's planning to pursue new projects outside of WACK.

The departure marks the end of another chapter in WACK's roster, which continues to be known for its experimental approach to artist development and rotating group compositions. While Riontaun hasn't yet announced her next steps, her optimistic tone hints that new endeavors may be forthcoming.
