Ippan džóšiki ( Minna zuretemasu) (S02E07)

Two suspicious figures appear in a dark alley under the cover of night. An unsettling air hangs over their secret exchange. "What do you need, asking me to come here?" asks the perverted woman with two horns. "Lend me your power," answers the melancholic man in a butler uniform. And so the most sinister and awful tag team begins to take action. (Crunchyroll)
