セルセル on the left (seruseru)
ササレレ on the right (sasarere)
but I don’t know what that means. Maybe onomatopoeia for something? (A lot of Japanese onomatopoeia has that kind of repetition – e.g. guruguru for something spinning in circles or pikapika for something sparkling – but I don’t recognize this.)
In katakana it says:
セルセル on the left (seruseru) ササレレ on the right (sasarere)
but I don’t know what that means. Maybe onomatopoeia for something? (A lot of Japanese onomatopoeia has that kind of repetition – e.g. guruguru for something spinning in circles or pikapika for something sparkling – but I don’t recognize this.)
It’s a reference to this image.
Huh. 🤔️
