A kid raised by five martial gods pretends to be weak while he's actually unstoppable, and every skill he's learned, combat, medicine, chess, cooking, becomes a weapon in figuring out who killed his parents. The show doesn't waste time on humility arcs; it knows what it is and moves. You're watching someone dismantle a city's power structure one perfectly-played game at a time, and the mystery of his parents' death pulls you forward even when the harem dialogue gets thin.

A young man comes out of the wilderness, where he grew up under the care of five enormously powerful grandparents. He heads back to the city with one aim: to learn the truth about who murdered his parents. He is accomplished in martial arts, music, chess, medicine and cooking, yet he hides his strength and plays the weakling to get the better of the people around him. With beautiful women at his side, he climbs past every obstacle, works to crack a startling mystery, and swears to become the city's master of every discipline and its unchallenged ruler. The ONA runs for 20 episodes and mixes action, adventure and fantasy.
