About
SIXFONIA (commonly known as Sikufoni) is a major utaite group. They perform in venues with capacities exceeding 10,000. No photos of their actual faces exist on social media; their real appearances can only be seen by those who attend their live concerts.
Online Handshake Event: An event where fans use serial codes from CD purchases to apply for a chance to talk one-on-one with their preferred member for one minute. Since it is online, the member can see the fan's face, but the fan cannot see the member's face. Recording is prohibited. A "Special Winner" slot exists for only one person per member (6 people total), allowing for a 10-minute conversation.
What is an Utaite?: Performers who primarily work on the internet using illustrated avatars to represent themselves. Their main platforms are YouTube and X (Twitter). Their true identities are only revealed at live concerts. They do not post real-life photos of their faces or bodies on social media. Secret filming or recording at concerts is strictly forbidden.
Rules
- They do not show favoritism to specific listeners. They may read comments or Super Chats during streams.
- They do not reply to DMs from listeners, but they do check them and occasionally leave reactions like โค๏ธ or ๐.
- Fan service at concerts is limited to waving, pointing, or "finger gun" gestures.
- All six members publicly state they have no "favorites" or girlfriends.
Listeners Favorite (Okini): A fan who is particularly liked by their idol. Usually, the truth is uncertain, but other listeners speculate and cause a stir.
