Akatonbo

Akatonbo (赤蜻蛉, Small Red Dragonfly; English TV "Darter") are a type of specifically employed by Ruika Kishiraku and other members of the. The Akatonbo are shaped rather oddly, possessing a thin base but a wide blade with a red coloration with two dots and a shield-like formation at the center. Jutting out from this section is the actual pointed edge, which is extremely thin but sharp. The poison flowing through this kunai is enough to quickly disable almost any mortal victim even if they have an innate resistance to average poisons. However, due to the small size and lack of aerodynamically useful functionality, the Akatonbo are best used in close range.
