Something that I enjoy about Romantic Killer is that even though the show somewhat dips into the "I'm not like other girls" trope, Anzu is never really isolated from girls. She gets along with many of them really well, and her closest friend is a girl. She never judges them for having feelings for Kazuki, she just dislikes the ones who harass him. She has her quirks that we don't see in other female characters, like her competitiveness, but the other girls are supportive of that. Even though there are some pretty desperate girls (the ones who got purposely hit by a car for a date), they aren't necessarily the majority.
