Two Fire Dragons! A Stolen Technique!!
Recca faces the copycat ninja Kashamaru who wielded the madogu Nisebi (Fake Flame). During the fight, Recca was given a riddle by Rui (One of the Karyu) and was able to solve her riddle and created a fog illusion (in the forms of Gashakura, Jisho and an impersonation of Kashamaru himself) against Kashamaru. Recca emerged victorious. Tsukishiro and Kashamaru are then sent to the Majigen dimension. Recca was supposed to fight Gashakura who stated that Kashamaru applied sleeping potions to all his weapons.

Flame of Recca
Recca Hanabishi is a ninja, but is nearly killed in an accident. However, a girl named Yanagi heals him with her powers. Later, the two are tracked down by a woman who attacks them. She tells Recca to ignite his flame, but he is clueless. Just as she hurts Yanagi, Recca releases a powerful flame upon the woman. She is excited to see this. It turns out that Recca was a baby, from the Hokage Clan of the past, that was sent to the future in order to escape death. Now, Recca is the leader of the new Hokage Clan who must stop his half brother, Kurei, from kidnapping Yanagi.
