Just when you thought that you'll avoid problems in your new school after what happened to u in the previous one, you wake up one day to find a heart-shaped necklace with a colorful strange stone around your neck, and a note asking u to find the 12 knight of happiness. A dream, a lovely mysterious necklace, weird friends and a strange legend about another world. Are u up to the challenge with those keys little lady? (Hetalia characters are for Hima daddy, you is for you , I just own the story)
