I've posted reasons before, as to why her songs do shit, mainly because the lyrics are shit but also:
- Irys has technique, but it still doesn't feel emotional. No, I don't mean SOVL, I'm just saying the emotional effects of it isn't as felt as in other holos like Moona/Towa/Suisei.
- The MV itself isn't memorable, even Anustart and Play Dice is more memorable, come on. This still feels amateur.
- Irys as a brand, she objectively has a much weaker brand than other singing holos, you can't even compare her to the music powerhouses like Suisei/Mori who are able to be instantly recognized.
-She doesn't have the stage presence/ diva-esque quality that Suisei/Moona have. She still feels meek/shy when singing.
- Her songs are dropped like guerrilla songs/ with 0 marketing or hype beforehand. This just straight up kills them on arrival and means she won't even get the initial boost to help it into the YT algo.
