Іджюїн Тадатомо

The apparent leader of the Baka Trio, Bacchi-Gu is an overweight, bespectacled pervert who has no shame. The arrival of beautiful girls to Kanenone seems to send him out of control. He does things such as drinking the bath water the girls recently bathed in, to making a nipple print of his own nipples so he can imagine they belong to a girl. Bacchi-Gu is considered to be the lead comic relief of the series (although the series is mostly comedy) and is the male mascot of Green Green. In episode nine, he has a run-in with the scarred male bear from a previous episode. During the episode, he gets lost in the forest, after getting separated from Midori.

He sees the bear, and mistakenly hugs it from behind, thinking it is Taizo Tenjin. The bear thus misunderstands him, and begins to rape with Bacchi-Gu. The episode finishes with the scene of the bear raping Bacchi-Gu, although the act is hidden by a bush. Source: Wikipedia
