She's at a conveyor belt sushi place!? Belle: "Wilt thou not take me...?"
One day
Guest goes to a conveyor belt sushi restaurant. While casually picking up plates... Something that isn't sushi comes drifting from the other side of the lane. "...?" Plop.
Staff "Excuse me, customer." "One Demon Lord will be 330 yen." "Huh???" "It's this week's recommendation." "That's not a recommendation!?" Demon Lord "Please... don't return me." She looks dejected.
But actually... She's the real Demon Lord. The strongest in the Demon Realm. The Final Boss. Yet she's only 16cm tall. Magic "Perish." Bam!! Only the lights in the house go out. "..." "Out of mana."
Dignity
"I have conquered the world." "Oh, really." "...Dost thou not believe me?" "Nope." "..." (´・ω・`)
Food "Dost thou like sushi?" "Salmon." "O-Oh, same!" "I like salmon too."
Demon Lord Castle
It exists. In another world. However, The exit of the teleportation magic Is that conveyor belt sushi lane. So demons drift by periodically.
Demons
Dragons. Vampires. Devils. Retainers. The Four Heavenly Kings. They all come drifting down the lane. "Demon Lord!!" "Please go home."
Manager "Ah, another customer from the Demon Realm." He's completely used to it. Hero The Hero also comes drifting down the lane. "Demon Lord!" Demon Lord "Today is a truce." Hero "I want to eat salmon." Demon Lord's Dream "...I." "Want to grow bigger." "Why?" "When I sit on thy shoulder, I slip."
Belle's way of getting attached is basically like a puppy.
Everything in this world is peaceful. No one hates anyone, And while there might be romantic jealousy, Nothing dangerous happens.
Nothing but peaceful things happen in this world.
