Battle of the Great Climb

After he was insulted by an Agasha ambassador in court, Akodo Yokutsu used it as an excuse to assault the Dragon lands, carefully avoiding the Dragonfly Clan.

During the assault, Yokutsu demanded to be allowed to duel Mirumoto Asijin, who had married his betrothed seven years ago, to redeem his honor. The Dragon Clan Champion Togashi Ayoko arranges the duel and Asijin is slain. Asijin had made a deal with Ayoko however and now the Dragonfly were under the Dragon's protection.

The arrogant Yokutsu declared himself the Dragonfly Clan Champion and his intention to marry Isawa Maroko once more. Asijin and Maroko's son, Kuyuden Tonbo challenges Yokutus to a duel and kills him reclaiming the Dragonfly.

Form then on the Dragonfly have been the official emmisaries of the Dragon Clan.
