Gintama Season 3 Episode 32

Otose arranges for Gintoki and the gang to spend their winter break at a hot spring inn located deep in the mountains. Anticipating a secluded hot spring bath, the group hikes their way up the mountain trail, only to arrive at a completely deserted and run-down inn. With no available bus to return to Edo, the gang has no choice but to stay at the inn. The inn’s Okami Oiwa welcomes the group, but Gintoki and Shinpachi notice a transparent being standing behind her back!
