The description starts with, "Kawakami Momoyo is a notorious, woman-chasing, large-breasted master fighter." If she is a habitual woman-chaser who then chases a man, then the category tag "LGBT Character in a Non-BL/GL Manga" would apply, because she'd be the B for bisexual.
I'm not going to rate it because I haven't read it, but based on its description, I will put the tag in. I wrote this comment to explain the reasoning for the tag and, if if the description is wrong, encourage y'all to change it. 🙂
Well, that, and having had the following conversation before, I thought that there might be someone out there who might need the clarification:
Me: "She's taking care of her sick boyfriend."
Someone else: "Oh. ... Um, does that mean she's heterosexual now?"
Me, exasperated: "She's bisexual! BI as in TWO! If she's serious about being exclusive with a certain man, it just means she's not with a woman right now."
