Plot
Bojji is a deaf, powerless prince who cannot even wield a child's sword. As the firstborn son, he strives hard and dreams of becoming the world's greatest king. However, people mutter about how he is too incompetent to become the king.

Undeterred, Bojji is able to make his first ever friend, "Kage" (shadow) — a literal shadow on the ground who somehow understands Bojji well. (Kage is a survivor of the Kage assassin clan that was all but wiped out. No longer a killer, Kage now makes ends meet by stealing.) The story follows Bojji's coming-of-age as he meets various people in his life, starting with his fateful encounter with Kage.
