Chiitan is the official Kawaii ambassador of Varrel, the prominent Japanese e-Sports team.

Chiitan officially joined the Japanese professional e-sports organization VARREL in July 2026.

Rather than just serving as a standard promotional ambassador, she was actually signed to the team's official roster under a newly created "KAWAII" division. This partnership is highly thematic: VARREL relocated its headquarters to Akihabara just a month before signing her, which perfectly aligns with Chiitan's established lore as an "Akihabara-born small-clawed otter fairy".

Through this collaboration, VARREL features her on their official team member page and produces co-branded esports merchandise, including VARREL x Chiitan acrylic stands.
