__Guardian Hearts__ [AniDB](https://anidb.net/anime/783) / [MAL](https://myanimelist.net/anime/824) "Maya, Kurusu, and Chelsea hit it off really well when trying to get revenge on Guardian Hearts for making them suffer. Maya and company thought that Guardian Hearts usually appears when Kazuya is getting along with a girl. Not knowing that Guardian Hearts is actually Hina, they leave her alone with Kazuya in an attempt to lure out Guardian Hearts." __Guardian Hearts Power Up!__ [AnidB](https://anidb.net/anime/3069) / [MAL](https://myanimelist.net/anime/3157) "The girls are still fighting over Kazuya when two new girls appear, from a rocket no less, and one of them claims to be his wealthy fiancée! Amidst all this, a new enemy makes her presence known, forcing the girls to turn against each other while draining their innocence away." Note: Didn't find these releases on the tracker, because it was subbed way before Nyaa even existed.
