Tomoe is a swordswoman who also has some very mild anti-magic armaments to defend herself with. These “grenades” won’t really be of much use in a fight so she will have to defend on her magic sword. Tanya’s also a sword fighter so it will ultimately come down to who is the better fighter. Tanya’s incredibly obscure so there’s the chance that she has some kind of special ability, but gathering intel on her was tricky so from what I have gathered, Tomoe would take the win here. Her sword skills have led her to victory! Tomoe wins.
