Fishy Tales of the Nekomata is a downloadable scenario for Muramasa Rebirth. It was released in Japan on November 7, 2013 and in North America on January 14, 2014.
The scenario follows Okoi, a Nekomata that is tasked with delivering a prized tea set to the shogun. However, she is pursued by her family’s chief retainer who will stop at nothing to reclaim the tea set.
Unlike the main protagonists, Miike Okoi does not use Demon Blades. Instead, she fights with her claws. The “Forging” mechanic has been replaced by a skill tree that will allow the player to improve and strengthen her various abilities. Finally, Miike Okoi can use her Nekomata magic to use more powerful abilities.
