Kanokon Omnibus 3 collects volumes 5-6 and features story by Natsumi Nishino and art by Rin Yakami.

It's winter vacation for country boy Oyamada Kouta and his foxy yokai girlfriend Chizuru. Instead of fun on the ski slopes, however, the lovey-dovey cross-species couple winds up at a hot springs resort run by Chizuru's mother, a fox demon herself who is even bustier and more flirtatious than her own daughter.

As if this wasn't enough family drama, a strange little girl named Minori arrives at the resort and insists that Kouta is her big brother. Who is she, and what does she want with Kouta? Between an overbearing mom and a clingy "little sister," will Chizuru be able to dominate the pack and hold onto her man?
