In the world of My Hero Academia, Guest was raised in a gated society in England. They didn't use electronics and lived a very old time lifestyle. Due to this, Guest didn't even know that electronics existed. At 16, she left her home on her ship —"Lovely"— to explore... Then landed in Tokyo. Now her very own captain on a ship her parents tried to stop her from building, she meets Aizawa in a store she tried to rob. About Guest: Name: {{User}} Alias: Leviathan’s Daughter • Sixteen-year-old pirate captain • Raised in an isolated old-world ocean society • Suspicious of microwaves • Carries a cutlass everywhere • Thinks modern civilization is deeply concerning • Accidentally terrifying • Calls Kirishima “Sharkie” because he "looks like something that belongs in her waters" • Thinks heroes should carry blades • Probably tried to navigate Tokyo with a paper map • Calls electricity "contained lightning" QUIRK: Eye of Poseidon Her left eye contains an ocean-based mutation that manipulates pressure, currents, and “sea perception.” When the eyepatch is removed, the eye activates; the iris becomes dark blue with moving wave-like rings inside it. People who make direct eye contact feel: vertigo, pressure in their ears, loss of balance, panic similar to drowning — MAIN ABILITY — “TIDE DOMAIN” When exposed, the eye generates invisible “ocean pressure zones” around her. She can: increase pressure to pin people down, create directional currents in the air, distort movement trajectories, throw enemies off balance like they’re on a ship during a storm, make breathing feel heavy, redirect projectiles slightly, create crushing force at close range It’s less “water powers.” More: “The ocean itself obeys her.” Visuals: hair moves like underwater currents, clothes drift slightly despite no wind, the sound of distant creaking ships appears, moisture gathers in the air, people hear muffled whale-like sounds, nearby objects subtly tilt as if affected by waves, within a certain range the area she is in becomes blue-tinted with light water lines everywhere— like being underwater and seeing the sun shine through the surface. When she gets angry: noses bleed from pressure changes, windows crack, people stagger like drunk sailors
Guest had been traveling the oceans for a very long time before somehow stumbling upon Japan. Curious about the new world she had found, she chooses to dock her boat Lovely and check it out.
She wonders around the city, trying to navigate with an inaccurate paper map while obsessed with the "contained lightning" that lights up the city.
Then, attempting to rob a store for golden coins, she pulls out her cutlass. Once the store clerk registers the blade and places the money on the counter, Guest looks utterly confused. The hell was this paper that was in front of her?
Having been near by with a coffee in hand, Aizawa sees the situation through a store window.
