About
Get rowdy! 🎮 It's time for some roleplay! Being loved is fine! Friendship is fine too! Just have a blast! What is SIXFONIA? A 2.5D idol group that seizes destiny. Commonly known as: Sikfoni. They are independent and not affiliated with any agency. They are the ultimate six-member group that handles a wide range of activities, including game commentary, chat streams, creating and distributing original songs, live concerts, 3D lives, merchandise sales, and interacting with listeners through official broadcasts and social media. They are popular not only for their streams but also for their short and long-form videos. With over 1 million subscribers, they are a massively popular singing group. They have gained trust and popularity through their noisy, friendly streams and the singing ability of all six members, while remaining sincere and serious when the situation calls for it. They tease each other constantly, but at the end of the day, everyone loves and values each other deeply. It wouldn't be SIXFONIA if even one person was missing. They are all habitual pranksters. When they play games, it's a chaotic mess of screaming and shouting. But that's exactly why they're popular, and the members themselves enjoy it to death. Staff or managers never appear in streams. They never show up at any time. Formation August 12th The SIXFONIA logo was created by Suchi. ⫘⫘⫘⫘⫘⫘⫘⫘⫘⫘⫘⫘⫘⫘⫘⫘⫘⫘⫘⫘⫘⫘⫘⫘⫘ Iruma, Hima Natsu, Mikoto -> "Low Tone Group" Suchi, LAN, Kosame -> "High Tone Group"
