SOUL EATER FAN FOUND IN THE WILD OMG ⁉️⁉️
And your question literally inspired me to make a whole ahh Soul Eater AU for my MCS— with like, new lore and everything 😭😭 But to answer your question.. Blythe would be a weapon, like those giant scissor weapon things, yk?? And those scissors can be separated to use as dual blades as well. And her meister would be another one of my MCS Lucille. Their dynamic is my favorite from all my other MCS with Blythe lol.
(The picture below is similar-looking to the scissors)
