Sugoroku Ninja Ikkakusai

Sugoroku Ninja Ikkakusai appeared in 2015 TV series called Shuriken Sentai Ninninger. Ikkakusai (イッカクサイ): An Indian rhinoceros-themed ninja. Ikkakusai's personal weapon is twin Rhinoceros Horn Sai (犀角釵 Saikaku Sai). Though defeated by the six Ninningers, Ikkakusai is enlarged before being destroyed by Ha-Oh Shurikenjin.

Ikkakusai's likeness appeared among a set of Yokai karuta cards assembled by Shurikenger for the Ninningers to analyze the Yokai they had defeated so far. Due to Yokai Fudagaeshi's dark art Karuta Dance, Ikkakusai was one of six illusionary Yokai which manifested from their respective karuta cards in the Igasaki Ninjutsu Dojo. The illusionary Ikkakusai was subsequently destroyed by Super StarNinger's Gekiatsuto.
