This will be the first-ever IP collaboration for Shabu-Shabu Onyasai.

URL: https://www.onyasai.com//lp/202605_sixfoniaCP/ ■ Go on a "secret date" with the Sixfonia members. Newly drawn visuals are here. The theme of this collaboration is a "secret date with the Sixfonia members at Shabu-Shabu Onyasai." The newly drawn visuals express the situation of "What if the Sixfonia members themselves visited Shabu-Shabu Onyasai incognito?" The atmosphere of enjoying a meal together in a calm restaurant and the natural sense of distance create a sense of realism, as if you are truly spending time with the members. Furthermore, the members' personal opinions are reflected in the casual wear they are sporting. The styling incorporates each member's preferences and individuality, allowing you to enjoy a sense of their "true selves," different from their usual activities. Please pay attention to the playful worldview, as if you are spending a special time with your favorite member while gathered around a shabu-shabu pot in the restaurant. ■ Launching an "All-You-Can-Eat Course with Original Clear Card" featuring newly drawn illustrations. In this collaboration, we will be selling an "All-You-Can-Eat Course with Original Clear Card" featuring newly drawn visuals. By adding 330 yen (tax included) to the regular all-you-can-eat course, you can upgrade to a course that includes this collaboration's exclusive "Original Clear Card (6 types total)." The cards are distributed randomly, so you'll have to wait and see which member you get. In addition, each member's "Onyasai favorite menu" will be introduced, and the recommended menus that reflect each member's personality are a must-see. Furthermore, a "Drink with Original Clear Card" will also be available exclusively for this collaboration. This can only be ordered by customers who have ordered the "All-You-Can-Eat Course with Original Clear Card," allowing you to enjoy a limited-edition clear card along with your drink. We will deliver a special experience where you can enjoy the meal itself as "oshi-katsu time" with a limited design that can only be obtained here. ■ Limited digital merchandise available for exchange with "Sixfonia Points" also appearing. The Shabu-Shabu Onyasai official app will feature a special project for this collaboration, "Sixfonia Points." During the campaign period, when you visit Shabu-Shabu Onyasai and present the app at the register during payment, 2% of your total bill (including tax) will be awarded as "Sixfonia Points." Since regular menu orders are also eligible, you can naturally accumulate points while enjoying your daily meals. The accumulated points can be exchanged for original merchandise exclusive to this collaboration. We have prepared original phone wallpapers (7 types total) using the newly drawn illustrations, which can be exchanged for 20 points each. Through the Sixfonia x Shabu-Shabu Onyasai collaboration-exclusive wallpapers, you can continue to enjoy special moments with Sixfonia even after the collaboration ends. ■ A chance to win a complete set through a Follow & Repost campaign. Furthermore, we will hold a limited-time Follow & Repost campaign on the official Shabu-Shabu Onyasai X account. During the period, six people selected by lottery from those who repost the target post from the Shabu-Shabu Onyasai official X account will receive an "Original Clear Card Complete Set of all 6 types." 【Application Period】 Wednesday, May 20, 2026 - Sunday, June 7, 2026. This collaboration offers an experience of the Sixfonia world in various forms, from food and visuals to digital merchandise and SNS projects.

They made a shocking debut in August 2022 with their original song "J0KER×JOK3R." With their musicality and high planning ability as their weapons, they are mainly active by posting various original songs, challenge videos using their singing and voices, and cover songs called "utattemita." The channel has over 1.24 million subscribers, and they are a fast-rising group of six that is rapidly gaining popularity and expanding its influence. Their momentum knows no bounds. On Sunday, October 26, 2025, the group's first 3D live performance was streamed for free worldwide on the official Sixfonia YouTube channel and is available in the archive. Furthermore, they held two live-action concerts linked to the 3D live in November at Ookini Arena Maishima in Osaka and two concerts in December at LaLa arena TOKYO-BAY in Tokyo. 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. The tour ended in great success, attracting a total of 50,000 people. Reading in parentheses next to the name. (Top row, from left) LAN (Ran), Suchi, Mikoto.
