Yuki & Himiko are sisters and original characters created by Senpai during the start of the the shop 2+yrs ago!

Yuki : 22-year-old snow cat, is typically shy and reserved, but she feels more comfortable around her friends and family. She tends to listen to her sister more than anyone else.

Himiko: 24, may be full of herself and a failed model due to her attitude, but as a loving sister, she is always trying to help Yuki break out of her shell. Despite her shortcomings, she remains confident and uses that confidence to encourage Yuki.
