Rubina

Mite, a knight serving the kingdom, is captivated by the beauty of Princess Rubina. However, as he learns of her hidden side, Mite is conflicted. Nevertheless, he resolves to embark on a dangerous journey to please Rubina. And, he succeeds in collecting precious minerals in a cave where dangerous monsters lurk, and bringing them back to the castle. Oh. What business do you, a castle guard, have with me? I'm busy organizing this lovely collection right now.
