What If I Had Superpowers?

[The main story is complete. Mori Boss's fantasy travelogue side stories will be updated from time to time] "If," by Akadama, winner of the 206th Akutagawa Prize. One day, after opening the door, the entire world had changed, including me. My best-known work, "If," had even become a supernatural ability. Although "If" contained far too many hypothetical settings, that didn't mean I could accept a world that had suddenly changed... Oh, or the fact that I had suddenly transmigrated. Especially after learning that this world didn't even have the Akutagawa Prize... Akadama: At a loss.jpg Ability: If. After constructing a complete hypothetical scenario in your mind, you can make it real by expending enough stamina. If I could be taken in by a kind person If Dazai's inner darkness became tangible If Chuuya could grow to 180 centimeters If Mori's Alice-chan became a mature woman If Atsushi turned from a big tiger into a little kitten Everyone who has ever been subjected to an "if": You're done for. :) Akadama: Please, spare me! [kowtows] #The big shots all want to wring me dry# #These heartless people won't even spare a five-year-old boy# #I'll gladly give all my stamina to make every one of those heartless people cross-dress# Content warning: The protagonist repeatedly switches between looking five and twenty-two. Pairing: Chuuya Crossover, mainly Bungo Stray Dogs. See the supporting cast section for the rest. Upcoming: "[Crossover] So Many Older Brothers Dropped from the Sky." Please bookmark it from my author page. I am one of Shaiapouf's... clones. Just looking at my appearance, I'm a tiny thing with dazzlingly colorful... fairy wings. That's right, I'm eight centimeters tall. My original body was poisoned by the Rose and died. In theory, I should have died too, but for some reason I survived. Not only that, I keep dreaming, and the dreams feel incredibly real. I dreamed that this version of me transmigrated into one world after another, winning over lots of people through familial affection and growing into a young man through their love. I know it's a dream. But I never imagined that after I yawned and opened my eyes, I'd find myself surrounded by people from my dreams. They looked at me with concern and said, "Pouf, what happened to you? Why did you turn back into your original form? Was my love not enough...?" Me, one of Shaiapouf's... clones, Little Pouf, not even as big as an adult man's palm, forced into the middle of a battlefield of love... Heh. :) Known older brothers: Dazai, Chuuya, the cotton candy spirit, the Disciplinary Committee President, the Captain, and Sogo. [Basically, they all fight over their healing little brother (supposedly), with an absolutely delightful love-rival battlefield unfolding every day. Pouf is being a little menace and trolling his big brothers online.] #Seamlessly switching between a boy and a little fairy# #The apple of everyone's eye# Theme: "If" brings imaginary possibilities to life, but meeting you is an imaginary reality
