Lord Tamakuro was a supported of Lord Hikiji who turned traitor.

He secretly imported vast supplies allegedly to renovate his castle but no laborers were hired -- only lots of ronins. When Tomoe Ame payed him a visit, paying his store rooms a visit during the night, she found large plates of lead and teppo.

Meanwhile, Lord Hebi also noticed the rumors about the lord and sent Shingen, a Neko Ninja to investigate.

When the truth came out, Usagi, Gen Zato-Ino, Shingen, Chizu, Tomoe and a large number of Neko Ninja attacked the castle. The attacking forces were defeated, however, and Lord Tamakuro would have been victorius if Shingen hadn't been able to ignite the large supplies of gunpowder inside one of the towers of the castle.
