A kwami is the companion to a superhero in the series Miraculous Ladybug. This small creature is used to transform the civilian into their superhero self.
You're such a cute kwami!
No way! You're Ladybug's kwami?!?
The Japanese version of ‘how cute’. The character Kaguya Shinomiya uses this a lot in the manga called Kaguya Wants to be Confessed to, otherwise known as Kaguya-Sama: Love is War.
It is Shirogane Miyuki’s (another character) least favorite saying of hers.
