Tales of the Girl in the Box

The Box Girl exists to protect the treasures that belong to her inside her box. Anything she likes, the Box Girl will carefully place inside her box, keeping it in its most beautiful state. Until one day, a very beautiful person came to ask her for help. “Would you become my treasure?” “Ah, I'd be honored.” And so, an entire citadel was swallowed up by the Box Girl's box. I'll cherish and adore you as if you were my precious treasure. That's how I feel about you. A sweet romance between a Saniwa and the swords. There are absolutely no corpses inside the box! I've started three stories. Whichever gets the most saves will be the one I write.
