Ketsuryūgan

The Kerryūgan is a dōjutsu kekkei genkai, which appears in certain individuals of the Chinoike Clan. The Kerryūgan is recognised by its reddish colour, giving a special appearance for the users of this dōjutsu, characterised as holders of "eyes as red as blood". The Kerryūgan confers genjutsu casting abilities. Its power earned it comparison to the Three Great Dōjutsu.

Trivia

 * Ranmaru's Kekkei Genkai fits the description of the Kerryūgan. It is unknown, however, whether the two dōjutsu are one and the same.
