Ieyasu Tokugawa

Ieyasu Tokugawa (徳川家康, Tokugawa Ieyasu) is the main male protagonist of the Sengoku-jidai series. Once an normal high-school student from Hiei Academy, it is later revealed that he is the descendent of one of the unifiers of Japan Tokugawa Ieyasu, kicking off his new life.

Appearance
Ieyasu is a slim built young man of average height, with spiky black hair and light brown eyes. Throughout the series, he is often seen dressed in his school uniform in Hiei Academy even when in combat. However, when outside of school, Ieyasu is dressed in more casual clothes.

Volume 6, Ieyasu is said to have become considerably more muscular than he was originally.

After Volume 15, he now has an X-shaped scar across his chest, courtesy of Hideyoshi Toyotomi's Eien no Kizu.

After having his head crushed and dying at the hands of Gogyou in Volume 22, and being revived by Sanzou using Perfectus Immortalis and one of Hideyoshi's lives, Ieyasu returned to the appearance of his ten-year-old self and as such has the physical features and abilities of his younger self, though, according to Fuyumi and Ren, he still retains his scar from Hideyoshi.

Personality
Overall, Ieyasu has shown to be laid-back and collected a great number of times similar to his adoptive father, but there are times when he can also lose his composure in either awkward or embarrassing situations most of his time in his daily life, displaying great shock annoyance, and even at times anger.

Despite his laid-back and calm nature, Ieyasu can lose his temper after witnessing Kurvell forcing Fuyumi to strip in front of them to rescue the hostages. He won't even hesitate to maim enemies as he cut off Kurvell's arm using Onimaru. If the situation called for it, Ieyasu wouldn't hesitate to kill his enemies as he was forced to supposedly kill Guinevere Pendragon, albeit he did feel bad since she was both a friend and comrade, while understanding that he didn't have a choice as part of the plan.

He is also described as being very bold by several people, a trait he shares with his ancestor, as he was willing to, without hesitation, put himself in harms way to protect Fuyumi Tsukihime and Yoko.

Despite situations implying otherwise, he is not very perverted. He usually tries his hardest to show restraint and respect to the woman who acts lecherously around him, such as Fuyumi, Yoko and Momoji. He also chose not to have sex with Fuyumi at the log cabin they were staying, even though she suggested it, knowing he needed her family's approval first.

History
Currently, not much is known about Ieyasu's past, other than at some point, after his parents died, he was adopted by Ryujirou Shiranui and the Shiranui family.

Powers and Abilities
Aka Manah: In his final battle against Chacka, Ieyasu reached his 'Innate Evil Awakening' and became a Akamanah, a being whose broken the chains of fate. As such, he can increase his magic based on his training, a feat no person can do normally. Ieyasu also has an "attractive force", which enables him to force upon the fate that he desires; just releasing intimidation, he can cause the death of others if they don't put their focus on him. In his fight with Guinevere, he influenced the causation of "killing" and could cut through her Orichalcos Ippotis using Juzumaru.

Master Swordsman: Ieyasu is a remarkably skilled swordsman. Despite not training since his childhood, he cut Nobunaga Oda's magic bullet in midair, then held his own against Giovanni despite already being injured from before. As Ieyasu continued to face off against powerful enemies, he trained his sword skills with his father Ryujirou and Zhang Fei using his speed and skill to his advantage against even Hideyoshi and held his own against Percevall and Hakuto.

His sword skills has allowed him to fight against people who outclass him under normal standards such as Fuyumi Tsukihime and Kazuma Fuuma, receiving praise from both the Son of the Moon and Twin Wings. His skills were cultivated after he learned Edelweiss' swordsmanship, letting him fight on par with the Black Knight Guinevere Pendragon and defeated her, earning him the nickname as the Sword King.

"Without Foot"): Ieyasu learned the ancient technique by observing several different people use it, which combines breath control and footwork, letting him slip into the unconsciousness of his opponents making his motions far difficult to perceive until it's too late for them to avoid. He is able to use the same concept on a crowd of civilians by reading their blindspots, then walk and weave through them undetected, which impressed even a trained assassin. Ieyaus can mix the Trackless Step and normal footwork against "Necro Battalion" messing up their aim, a feat that Nangou Torajirou and Momozono Momoko can perform.

Enhanced Stamina: Through training with both Zhang Fei and Lü Bu, Ieyasu has developed stronger stamina, which increases as the series progresses.

Tenka-Goken
Tenka-Goken is Ieyasu's Technique. An powerful SS-rank Technique, it has the ability to summon five different swords, each named: Doujigiri, Onimaru, Mikazuki, Ōdenta, and Juzumaru respectively, each with their own respective powers and weaknesses. While Ieyasu was only able to one or two of the five at a time, he is able to summon an almost indefinite amount of one of the swords, such as when he fought Giovanni Lascaris with twin Onimarus, and when he constantly summoned multiple Odentas during his battle Hideyoshi.

After summoning the Doujigiri in the Twenty-Six Martyr Arc, he now has access to all five of the swords and is now able to summon all five at once, still in indefinite amounts.
 * Doujigiri: The strongest of the Tenka-Goken, and the same weapon the mythical hero Minamoto-no-Yorimitsu used to slay the Shuten-douji. 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 and create both ice and fire on a massive scale.
 * Pseudo Mana:
 * 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. It is a sword that was used to slay an Red Oni named 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, though this has yet to happen. According to Ieyasu, since awakening Rasetsu Onikimono, he has been able to speak with Sekiro, who now appears as a Rakshasa.
 * Hellflames : After Volume 7, Ieyasu now is able to summon black and red Hellflames without the use of Onimaru.
 * Pseudo Mana:
 * Enjin: Kyokumei no 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 no Fubuki: A unison attack between Ieyasu and Fuyumi.
 * Enlan
 * Jigoku Enlan
 * 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, 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.
 * Mikazuki
 * Plant Cultivation:
 * Ōdenta
 * Juzumaru
 * Purification:
 * Pseudo Mana:
 * 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 for a devastating attack of fire and ice, hellflames, wild flora, explosive energy and holy energy.
