Tenka-Goken

Tenka-Goken (天下五剣 lit. "Five Best Swords beneath the Heavens") is the SS-rank, Manifestation-type Technique of Ieyasu Tokugawa.

Abilities & Techniques

 * Goken Ashura: A technique based on Soujirou's Triskelion, in which he quickly attacks with and rotates between his five swords, using each of their abilities simultaneously.
 * Soumaru: Gokuenki Hijirijuzu (：): An combination technique between Onimaru and Juzumaru.
 * Persephone Hadal: An combination technique between Onimaru and Mikazuki.

Doujigiri
The strongest of the Tenka-Goken and the same weapon the mythical hero Minamoto-no-Yorimitsu used to slay Shuten-douji, Doujigiri is the fifth and the final of the Tenka-Goken Ieyasu has summoned. Taking the form of an long nodachi, with an bloody-silver blade and purple handle, it possesses great demon-slaying abilities and has the ability to control both ice and fire.
 * Bake-kujira: This is a technique which belonged to Iemon Tokugawa, which Ieyasu could use when merged together with Sanzou, where Ieyasu stabs Doujigiri into the ground, releasing cold winds and causing the ground around him to freeze, reportedly at absolute zero, at a rapid pace.
 * Ikkaku: This is a technique which belonged to Iemon Tokugawa, which Ieyasu could use when merged together with Sanzou, where Ieyasu uses Doujigiri to freezes the target the moment the tip of the sword touches the target, then the piercing strike would break the frozen target.

Onimaru
The first of the five swords that Ieyasu summoned and his primary weapon, Onimaru is a sword that was used to slay the Red Oni Sekiro, thus cursing both the sword and the man Tokimasa Houjou. An cursed sword, a tsubaless katana to be more specific, with an raven black blade and burnt bandages around the blade and handle. It has the ability to generate powerful red and black colored flames that can never be extinguished, even if Ieyasu were to be killed, and, as an cursed sword, it has the ability to slay both holy and cursed creatures. As according to Zhang Fei, Onimaru is the sword that Ieyasu has the most control over, yet, as, even when slayed, Sekiro is still alive through the sword, it has the chance of sending Ieyasu into an frenzy if overused.
 * Hellflames : After Volume 7, Ieyasu now is able to summon black and red Hellflames without the use of Onimaru.
 * Enjin: Kyokumei Kokken: Based on his older brother's Shin Geppa: Hitomaku Noh, in which Ieyasu absorbs and concentrates all of Onimaru's potent hellflames onto the edge of the blade, severely deforming it, but allows Onimaru to eradicated whatever it touches to nothingness for a short time frame. Even an powerful defensive technique like Sanzou's Dharmachakra cannot stand up against this technique.
 * Jigoku Enlan
 * Jigoku no Fubuki: A unison attack between Ieyasu and Fuyumi.
 * Onimaru Armor (, lit. "Armor of Onimaru"): After training with Zhang Fei and Lü Bu, Ieyasu was able to develop an armor for the sword, by channelling both his own ki and the ki of the sword and forming it into an demonic-looking, black and red samurai-like armor with blue horns. Dubbed as the Onimaru Armor by Momozono Momoko, Nangou Torajirou and Nishitora, it has the ability to protect Ieyasu from projectiles and magic-based attacks such Raijinjuu, and, as according to Yoko, Nishitora and Liu Bei, has an foul and demonic aura.
 * Rasetsu Onikimono: Ieyasu's Awakening. An improved and polished version of the Onimaru Armor, dubbed as Rasetsu Onikimono by Ieyasu, it increases Ieyasu's power a hundred-fold, having power comparable to that of Demon Lords of the Underworld, allowing him to fight on par with a Demon God-empowered Chacka, then defeat and kill him.
