Guardian Hearts  

Gatsu, がぁ~でぃあんHearts, がぁーでぃあんHearts

The three individuals, Maya, Kurusu, and Chelsea, had a great time working together when trying to seek revenge against the group known as Guardian Hearts for causing them distress. They believed that Guardian Hearts would appear whenever Kazuya was interacting with a girl. However, they were unaware that Guardian Hearts was actually Hina. As a result, they left her alone with Kazuya in an attempt to lure the group into appearing.
