I got this acrylic keychain for free from a Polish guy while we were out riding e-scooters. He had lots of anime keychains and gave me this one.

I have no idea what series it comes from. The back is completely transparent with no logo or copyright.

The character has:
• Purple hair with straight bangs.
• Pale skin.
• Half-lidded, bored/slightly annoyed expression.
• Purple background.
• Vertical Japanese text on the left.

I don't know if it's from an anime, manga, visual novel, or something else. Does anyone recognize her?
