Kanna-chan ♡

A young girl with white and purple hair and small horns looks forward with a neutral expression, then her eyes widen and her mouth opens in surprise as she raises her arms, before returning to a calm expression while looking at another character, then resting her chin on her hand while looking down, and finally looking up with a blush as a hand reaches toward her head. The scene takes place indoors, likely in a classroom or similar setting.
