The newly drawn visuals for this collaboration express the theme, "What if the Sixfonia members themselves came to Shabu Shabu Onyasai on a secret date?" The casual wear coordinates, which also incorporate the members' own opinions, result in special newly drawn visuals that reflect each member's individuality. You can enjoy a world full of realism and playfulness, as if you were actually visiting Shabu Shabu Onyasai with the Sixfonia members. Furthermore, each member's "Onyasai favorite menu" is also introduced. This is a special collaboration where you can feel closer to your favorite member while enjoying shabu-shabu. ■ Event Overview Campaign Name: Sixfonia × Shabu Shabu Onyasai Collaboration Campaign.

They made a shocking debut in August 2022 with their original song "J0KER×JOK3R." With their high musicality and planning ability as their weapons, they are mainly active by posting various original songs, challenge project videos using songs and voices, and cover songs called "utattemita." In the two years since their formation, their channel subscribers have exceeded 1.24 million, and they are a group of six up-and-coming talents who are rapidly gaining popularity and expanding their influence. Their momentum shows no signs of stopping. On Sunday, October 26, 2025, the group's first 3D live was streamed for free worldwide on the official Sixfonia YouTube channel and is available in the archive. Furthermore, they held two live performances linked to the 3D live in November in Osaka at Okini Arena Maishima, and two performances in December in Tokyo at LaLa arena TOKYO-BAY. In the spring of 2026, they held their 2nd live tour, including a performance at K-Arena Yokohama, the largest venue in Sixfonia's history. It ended in great success, recording a total mobilization of 50,000 people.
