I'm pleasantly surprised how capable Hati is in the manga. If I'm remembering things right, the description of her outfit in the game indicates that pilgrims like her are elite and handpicked from within Alqand's ranks. So it would make sense that they're a cut more capable than the average Alqand nymph since they would likely be alone when they act as propaganda, er I mean gospel spreaders in enemy territories. They'd have to be capable of handling themselves. Game Hati is adorably incompetent, but man, Manga Hati shows what is expected from someone like her.
She maintains her friendly attitude and good-natured idealism from the game. But she's not wholly naive. The manga shows she can handle herself in a fight, but she also shows good instinct. Correctly identifying the multiple red flags sticking out from Nanakino and even quickly picking up on the fact that she and Yoyo might be intruding on the Queen (Or whatever is the equivalent for that entity for Nanakino). Being an Evangelist from Alqand, she should be aware of Nymph societal norms across various colonies and a likely constant is that it's probably not a good idea for outsiders to just blindly approach a colony Queen (Doing that shit will most likely put an instant target on their heads as they pretty much operate on anime robot antgirl society rules.). Hence why she figured that the best course of action for now would be to fall back. But of course Yoyo had other ideas.
I'd joke about Yoyo being dropped on her head when she was a baby, but yeah, that's literally pretty much what happened lmao.
