As a magnet to horrors, Kouga tracked Kaoru's activities to make sure she's not harmed. Originally thinking Kouga is a stalker, she realized he has been protecting her as she keeps bumping into new horrors. Kouga wanted Kaoru close to him as possible; she took advantage of his words and stayed at his home when she became homeless. As the two get to know each other, they started to like each other. However, things got complicated with the arrival of Zero and Barago's machinations at play.
