Ranking of Kings

Prince Bojji is the eldest son of a king. But while both his parents are giants, he himself is a pipsqueak too feeble to so much as swing a dagger. To make matters worse, the whole kingdom gossips that the deaf, non-speaking Bojji is unfit to inherit the throne. The prince's days seem empty. But when a chance meeting unites Bojji with Kage, a new friend who truly understands him, his life begins to shine.
