Crossover: Holy Grail, Have You Finally Broken?

* This is an A Certain Magical Index alternate-universe story. The pre-release for Accelerator as the pairing is open. See my profile for "Crossover: The Self-Cultivation of a Snark Machine." The Fourth Holy Grail War now has fourteen teams competing. But somehow, the extra participants are all a little strange. For example, the heir to an Italian seafood family and the family's founder. For example, a card-playing boy and the Pharaoh from three thousand years ago. For example, a certain Blue King and the Red King, who died not long ago. For example, a boy who can see yokai and his grandmother. For example, the number one hero and his successor. And, for example... The ordinary transmigrator Akizawa Satsuki looked at the Accelerator he'd summoned and fell into deep thought. The Holy Grail can indeed summon heroic spirits from the past, present, and future, but this group here... Holy Grail, have you finally gone completely off the rails? tips: A genderless protagonist and a snarky comedy. Just enjoy it for fun, and don't overthink it, mwah. The story won't start for a while, and some details may be adjusted. Unless something unexpected happens, this will be my next story. Still no pairing, so please add it to your reading list! [Crossover] The Whole World Turns Small -- Is there anything more powerful in this world than the world's darling? -- Sure. Isn't it the world itself? * The second-in-command of HOMRA found two children outside their home. One was a soft, fluffy brown-haired rabbit who called himself Tsuna. The other, a child named Sekai, looked very well-behaved but wouldn't let go of their King. Then, in full view of everyone, HOMRA's King suddenly turned into a child of the same age. The second-in-command: ??? I was so startled I dropped my cigarette. But strange things kept happening. While they were livestreaming the number one hero's battle in an emergency, his opponent, a villain named AFO, suddenly went boom and turned into a child too. A famous organization of men in black suddenly fell apart. The reason? Their one and only bottle of real liquor had turned into a toddler? Then one night, a crowd of supernatural creatures in child form came knocking on HOMRA's door. "Tell that damn Sekai to come out!" The child named Sekai wiped away his tears. "D-do you all hate Sekai?" * tips: 1. Sekai can do anything. 2. Anyone loved by Sekai can do anything. 3. Sekai is a good child. Theme:
