Charisma.com announced on its official website that it will be going on indefinite hiatus.
The duo is ending its activities due to group member Gonchi's desire to retire from the entertainment industry. She will be helping out with her family's business instead.
"I've decided to withdraw from Charisma.com. Helping out with my family's business is important, so I've made this decision because I want them to succeed," she said.
Charisma.com's last activity will be a concert at Zepp Tokyo on January 27. The group will effectively disband after the performance is over.
The duo will be releasing a best-of album titled "Charisma.BEST" on January 10 to celebrate its years as as an artist.
