Yomikado Meijirou thought he was just an ordinary high school boy. However, after saving a devil, he discovers that he was born with the Seal of Solomon on his tongue, a special power that allows him to control all forms of sorcery and devils. He also discovers that he will die in three years as every use of his power uses up his lifespan. He is told that the only way to save himself is to establish a contract with the 12 Starlight Maidens who were born with a special sign somewhere on their body, and to do so, he must lick their signs with his tongue, which is where his sign is located.
