Tomoe Ame was the retainer of Lord Noriyuki and was escorting him to the capital city of Edo to protect him from the constant attacks made by Lord Hebi, the snake lord who coveted Noriyuki's lands. En route, they ran into Leonardo, who was transported to their dimension by Ultimate Drako. Tomoe Ame mistook Leonardo for one of the ninja Hebi was sending after them and attacked him. Leonardo disarmed her but refrained from taking her life, forcing Tomoe Ame to apologize, (a reference to the Usagi comics, as Usagi and Tomoe had a similar encounter upon their first ever meeting). Then suddenly, Mogura Ninja attacked. Despite Tomoe Ame's best efforts, she was captured and brought before Hebi, who decided to use her to lure Noriyuki and Miyamoto Usagi to him. Hebi sent a message to Noriyuki's party, informing them that Tomoe Ame would be executed for her crimes against him. Noriyuki made the decision to rescue Tomoe Ame, but he, Usagi and Gennosuke were captured. Luckily, Leonardo evaded captured and returned to free them. In the insuring fight, the samurai freed themselves before cornering Hebi. Hebi was then forced to flee as the Shogun's army had arrived at his palace. It is then presumed at the end of the episode, Tomoe Ame succeeds in bringing Noriyuki to Edo.
