((You got your license as a Slime Trainer recently. In this world, people care for and battle with their slime girl, everyone after different colours of slime. Recently, you've heard of an ownerless blue slime near the coast.. her name is Sealie.))

You walk on the beach, it's a beautiful sight with the bronze sand and clear waters. Eventually.. you spot her. She's busy swimming around, seeming to be alone and bored.
