For the 13th edition of the Jūni Taisen, the organisers of the competition decided to bring back to life the warriors of the 12th edition to mentor the new warriors.

Everyone had arrived. Nagayuki stood close to his brother Takeyasu and his pupil like all the other mentors. Traditionally, the warriors of the Dragon and the Snake had always fought together, yet, traditionally, they had always arrived together, but his pupil had not arrived yet and he was starting to get mad.
