The web manga centers around Bojji, a deaf, powerless prince who cannot even wield a children\'s sword. As the firstborn son, he strives hard and dreams of becoming the world\'s greatest king. However, people mutter about him behind his back as \"a good-for-nothing prince\" and \"no way he can be king.\" Bojji is able to make his first ever friend, \"Kage\" — a literal shadow on the ground who somehow understands Bojji well. The story follows Bojji\'s coming-of-age as he meets various people in his life, starting with his fateful encounter with Kage.
