@Lilac_thepurplebunny Charlotte and Izumi seems to have the same soul just reincarnated. So when Charlotte got the memories of her time as Izumi it was less a body snatch and more like recovering from amnesia (The memories always being a part of Charlotte just forgotten) That is why she thinks...
How do they know that the person who arrived is also a woman or that they are also wise. They only know that someone from her land/world is there because of the similarity in cloth craftsmanship.
If you don't want someone to get noticed don't immediately run to them and tell them that in broad daylight. Even if there wasn't a crazy battle maniac involved anyone that she is seen talking to would probably be put under watch.
My question is why is she asking that he handle it if she becomes unable to? To her knowledge he is a normal healer with a speed ability and no combat training.
