The Pure Yet Impure Grappler / Trespassing on Good Faith - S2.E5

Sousuke and Kaname investigate bizarre incidents where a masked predator attacks schoolgirls and gives them ponytails. With the help of a local policewoman, they set up a trap to catch the attacker using Kaname as bait.

To teach a stoic Sousuke the meaning of fear, Kaname takes him into a haunted hospital, but she becomes more scared than Sousuke. They learn that the haunted hospital rumor was perpetuated by the mother and son living there who wanted peace and quiet.
