[Crossover] The Brain Is Actually Me!?

Question: What's it like to wake up one day and discover you've become a man, or, more accurately, a brain? The Mount Fuji-looking head in front of me is still asking what my goal is. What can I do? I'm desperate too! "I'm done. Let's destroy this world." I only regret that there aren't any cigarettes inside this robe! Otherwise, I'd smoke a whole pack! - Even though I don't know how to smoke. But what I can't understand is why the Mount Fuji-looking head across from me seems so happy to accept my request for an alliance, while the ghostly man beside him, who looks exactly like me, seems to have a stomachache for some reason. ...Wait, they didn't take me seriously, did they? #I'm not actually a brain, even though I'd love to write an AU about a female brain and Geto. Let's not make it too dark, though, haha. #Geto pairing #First-person narration. I'm experimenting with the first-person perspective, so the style may occasionally twist into something weird (not really). Theme: Don't be too messed up (?).
