SKIYAKI Co., Ltd. (Headquarters: Shibuya-ku, Tokyo; Representative Director: Tomohiro Kokubo; hereinafter "SKIYAKI"), a company that creates platforms connecting creators and fans, opened the official website and fan club for si7ria (URL: https://si7ria.bitfan.id/) on Friday, May 1, 2026.
si7ria (read as Shinaria) is a female idol group that advocates a dark and decadent worldview themed around "sin." It is composed of four members: Haru Kisaragi, Chim Nem, Kairyuu Hi, and Sui Shinsou. The group debuted on December 19, 2025, with their 1st solo live performance "Paradise Lost" at GRIT at Shibuya. With the catchphrase "My darkness, you illuminate," each member embodies a "sin" and color: lust, greed, wrath, and pride. They are active in various ways, such as transmitting video content and appearing at events, mainly at live houses in Tokyo. They have attracted a lot of attention for their strong conceptuality and aesthetic expression.
What opened this time is si7ria's official website and fan club. On this site, in addition to delivering the latest information, you can enjoy exclusive content such as members-only blogs and group chats featuring the members themselves, which can only be seen here.
