A snowman turns into a Yuki-onna and engages in wild antics over summer break with her best friend Himari and Himari's aunt, Haru. Along the way new characters and friends are introduced and we get to see what their dynamics are with each other.
I think I can safely say this is a favorite of mine given it's great art, extremely expressive characters, excellent humor, retained focus, and easygoing setting. Unfortunately, translation stopped on this one but I would highly recommend reading what is available. While I doubt it, I do truly hope for an adaptation someday.
