Yeah they also look like Death the Kid from Soul Eater.
The art is def inspired by Soul Eater, I can see a little bit of Cronos in the Grim reaper too.
I like the background colouring and distortion which reminds me of the dynamic opening of SE too. It's nice seeing inspiration in works you like.
Also I love Cronos and Kid in SE, so I dunno maybe I'm biased haha
