Karin Uzumaki 

Guren 

Tayuya 

Haruna 

Kotohime 

Maybe Sakura, Anko, Hana

I Will not be adding Temari, Konan, Mei, Kurenai, TenTen or others to the harem. Because it doesn't go with the plot I've made so far, doesn't matter much because I'm debating adding an 18+ scene and they have partners already in the plot. For some of them they're the main love interest in other stories of mine, so I like to switch pairings around each time to make the stories feel more unique.
