User Summary Magical Warrior Diamond Heart isn't all about saving kingdoms, though, as you'll get to spend a lot of time getting closer to the other magical warriors who join you to help out. Male, female, and nonbinary relationships can be formed with each of these characters, or players can just become close friends with their crew, depending on what they feel comfortable with. If you feel you have time to play matchmaker while dealing with the Nightmare Agency, you can, as friendship and love are, deep down, the keys to overcoming the evil that's overtaken the crystal kingdom.
