Karakurenai

«Karakurenai» is a curved katana used by the guild leader of «Fuurinkazan», Klein. This sword uses the fairly common «Katana» skill which is unlocked by training the «Curved Sword» skill sufficiently.

Klein most likely uses Karakurenai up to and including the clearing of the 75th floor of Aincrad.
