Sakura Sakurakouji meets Ogami in a most unlikely situation. She witnessed him killing a criminal by blue flames and he doesn't feel any remorse about it. Then she discovers there's other people similar to him with powers and they're called the Code: breaker.
Few years before the anime, a lot of people already suggested the manga. But I was told and I've read that it's actually a shonen. That's why when I learned that it's going to be animated, I just have to watch it. If you want to get your boyfriend to watch animes with you then this is something you can both enjoy. Seriously, my husband and sons (my real-life reverse harem) stops whatever they're doing and watch it with me. It has a lot of fight scenes, powers and a reverse harem vibe.
