Yes, I can see how abridging Reika's "keikaku" and comparing her to Among Us of all things, one can see how she would be... Annoying.

No one completely believed her. For the past few EPs, both Ogami and Daishinji are clearly shown to be distrustful of either side. We dunno much about Ren, only going "Kento-kun" every second, and Rintarou is pretty much the closest we have to someone 'believing' her. Looking at it from a different angle, Reika only planted half-truths on everyone, it was Touma's lack of communication skills (for the plot) that caused him to be kicked out.

Edit: my bad for my passive aggressive tone. I just found comparing Saber to Among Us to be a bit distateful
