A Sandwich Cookie and the Living Dead

He is the nonexistent fourth member of the original story, with no cursed energy yet still one of the “strongest.” No name, no appearance. Consumed by the “technique,” his first mission is the Star Plasma Vessel. Erase curses, save his juniors, and use the strongest mind to do the most outrageous things while staying as inconspicuous as possible. Riko, Satoru, Suguru, Haibara, Nanami... Every one of his friends will be saved! But... Gojo the Cat: I'll feed you your favorite Kikufuku first~ Geto the Fox: Satoru is being too rough. I'm the better choice for you~ Shoko the Tanuki: Oh my, you can handle two at once... Which one do you like better? What are you guys doing! 1. A sweet story, main plot complete. 2. Midsummer, cicadas, and soda run through the whole story. 3. My own OOC Jujutsu Kaisen fanfic, with Gojo and Geto both vying for you. (Is this just intense friendship for now?) 4. It starts in summer during the Hidden Inventory arc. 5. Amateur writing, no-brains thrills, and “best friends” from the start. 6. No logic, and opinions on the protagonist will vary. 7. Told in the second person.
