Sword of Winds, Kuga

The Kuga (空牙刀, lit. Sky Fang Sword) is an air themed nodachi sword and the second weapon Samanosuke will come across in Onimusha 3: Demon Siege. While slower than Tenso, it possesses a greater reach. Samanosuke obtains it in Notre Dame, after completing the puzzle in the main hall by purifying the four statues.

The Kuga's magic allows Samanosuke to fling a crescent shaped gust of air when swinging the blade (two at high levels). The gust travels a wide distance and is able to strike multiple enemies, but it's unilateral direction limits its field of effectiveness.
