It's better not to spread misinformation of historical figures. Though Joan of Arc didn't fight enemies in battle, she had an active role in the battles and was wounded multiple times in battle. She also wasn't executed for wearing men's clothes. It was a political execution by the English for an advantage against the French. She was reported to have worn men's clothing in prison since it made it easier to fend off being raped by the soldiers.
People in these comments are missing the very obvious possibility that Aina knows way more than MC due to the government's foreknowledge of the event. We know that 1) the government knew about this ahead of time, 2) the government prioritizes its more valuable citizens (as an example, Aina's watch is superior to MCs) and 3) Aina is considered "more valuable" than MC by the government. He is a 5 star football player while she was 5 star in something secret. Thus, it is highly probable that the government prepared her for this event ahead of time making her foreknowledge completely explainable.
the only thing that confuses me at this point is how the others know more than the MC, bar taking longer to heal the other had only completed 1 zone as well so why is there such a difference in what they know... if anything the MC show have higher stats than all of them, but he some how doesn't... still confused about this
