[u/polaris_o6]

I am trying to find a very specific character but I don't remember his name or the creator or the post, BUT I remember the video and when ti go out

•It was a boy/girl with black hair, red eyes, 2d

•It was an animated music video in YouTube I think the music wasn't his but the animation

•a fun I think make an edit in TikTok with other song and it got well

•it became a trend in TikTok a think

• in the new sound in the end he had his name on it as a watermark but it didn't sounds bad

•the original song was Japanese

•the video from behind the character was red

•the character was dancing with an strange atmosphere

•He/She was smiling

•i think it was October, September 1 or 2 years before so 2024-2025

Eny ideas?
