Tokugawa Ieyasu (徳川家康?) is a Servant created for the parody work Koha-Ace. His primary class is unknown, but he can switch between Saber, Archer, Lancer, Rider, Caster, Assassin, and Berserker classes.
The Servant's True Name is Tokugawa Ieyasu (徳川家康?), one of the three great unifiers of Japan. He once served under Toyotomi Hideyoshi. He will not be summoned by Hideyoshi's Transcendent Dazzling Castle of the Sun unlike the rest of Hideyoshi's followers. The real Tokugawa died early on in his reign, but they used the Tokugawa System (徳川というシステム?) of body doubles to hide that fact. The summoned Tokugawa is one of those body doubles.
Much like Hideyoshi is given the moniker of "monkey", Tokugawa is named Tanuki (タヌキ?) due to his appearance.
Tokugawa possesses no Personal Skills or Class Skills on his own, lacking power due to being a body double of Tokugawa, but his Noble Phantasm lets him swap between all seven of the standard Servant classes. Each class manifests the power of one of Tokugawa's powerful warlords, so they allow for adaptability through versatile switching of classes to respond to any situation depending on the opponent. Due to this, he has high compatibility against Nobunaga. Each has its own status, abilities, and Noble Phantasm. The manifestation of each class is dependent on the physical Noble Phantasm, so the class can no longer be used should the corresponding Noble Phantasm be destroyed or stolen. Due to this, he has low compatibility against Hideyoshi due to Blade Taker.
