## Trivia

* The fandom's name is SWAG. "I'M SWAG", which is also the 1st single, is a song that can be said to be the theme of ONE N' ONLY, and the fans are the closest to ONE N' ONLY, so the name was given.
* Their music videos reached a million views in less than 24 hours and their 2nd single Dark Knight placed first on both the Oricon chart and Japan Billboard Top 100.
* They have a song called "My Love" (from the single Category / My Love), that became their signature song and is still often sung at live and is the only song with an MV released 4 years after the song's release and the only MV made following fan's wishes. The MV was first aired on the live-streaming project 5N'5 ~55555~ (5 hours 55 minutes 55 seconds live streaming on October 7, 2023).
