Jachi

Jachi (ジャチ, Jachi^?) is the 11th Demon Lord of the Great Demon King Army, and the pivotal and main antagonist of the Introduction Arc.

Appearance

Jachi is a large, muscular being with dark-blue skin on his back, forehead, around his eyes and nose, the back of his legs and arms, and light skin on his chest, abdomen, the front of his limbs and the rest of his face. He has sharp eyes with an perpetually open third one on his forehead, large fangs, and fins protruding from the top and both sides of his head. His attire consists of a speedo, arm guards, leg guards, and a large cape fastened with a shoulder pad that resembles a jaw. Spikes protrude from most of the armor with the exception of the right arm guard.

Personality

Jachi is very arrogant and confident in his strength, as seen when he orders his underlings to stand still and spectate his battle against Hallow's party, or when he's annoyed by his underling's warning of the outside world. He also heavily looks down on humans, remarking them as "frail" and "trash". Jachi's rather sadistic nature makes him play around with Hallow instead of finishing immediately, going as far as taking a sword strike without any scratch to mentally break Hallow, resulting in Hallow's inner fear of demons afterwards.

Despite his sadistic and haughty nature, Jachi appears to have some form of affection for his soldiers. When the Madalans arrived at the hero's fortress, Jachi sent three other combat executives to assist Kiva and ensure his safety. Upon arriving at the aftermath of the battle at the hero's fortress and witnessing his army slaughtered, Jachi showed slight anger and demanded to know if Uki was responsible.

Even with the changes to the world, including the arrival of vastly different beings from other worlds, Jachi showed no concern. At most, when facing one of the Madalans, he showed some interest in their unique abilities that didn't utilize mana. Thus, he slowly broke down and humiliated Uki by showcasing his superior strength before defeating him. Even so, Jachi is capable of becoming serious when facing what he considers a true enemy, such as when meeting Ginbak. True to his lust for violence, when the 19th Demon Lord Nyudo interfered in his battle against the Titan chieftain, Jachi was deeply infuriated that the fight had been stolen from him.

Plot

Introduction Arc

Jachi is first seen waiting for Hallow at his castle. When the hero and his party arrive, he welcomes them and looks down on humanity, and demands to see their power. Regis responds with Final Level, Inferno Magic: Hell's Flame, but the fireball in question does no damage to Jachi as he blows away the attack. He then flicks a speck of earwax which splits Regis in half, to Hallow's horror. Jachi then approaches them as he kills Railu and Mazulina from the high concentration of mana covering his body, which prompts Hallow to aggressively attack him. He compliments his sword's qualities as Hallow tries to land a hit to no avail, and even dodges several continuous attacks that are aimed to his vitals, all while complimenting Hallow's swordsmanship. In response, he grabs the sword's tip which causes Hallow to lose his right arm. He then comments the sword is the last resort of humanity, and tells the hero to cut him with the sword. The hero tries to cut him one last time but fails as the sword breaks in half because of Jachi's durability. His mere aura shocks Hallow, which prompts him to be disappointed at the hero as he kicks him out of the castle.^[1]

Titans vs The Neo-Humans Arc

Jachi is next seen in his castle hearing a report from Kiva. Afterwards, he decides to venture outside for himself and has a telepathic conversation with Nyudo. They briefly discuss the recent maneuvers of several Demon Lords. Nyudo extends an invitation to Jachi for a bit of amusement, but Jachi's curiosity lies with the Great Demon King Byakuo's perspective on the unfolding events. Despite this, he learns that Byakuo has chosen to remain silent. Nyudo muses that for a demon of such unparalleled stature as their king, such trivial shifts in the world are of no consequence for him. The conversation takes a turn when Nyudo reveals his wish to encounter a hero, leading Jachi to question whether a hero has yet graced Nyudo's castle. Nyudo responds with a denial of seeing any hero visit him.^[2]

Demon Lord Arc

Jachi encounters a group of titans while exploring the new world. When one of the titans lunges at him, Jachi casually kills the attacker. He expresses disappointment at the titan's strength, but before any of the other titans attack him, Gori decides to fight the demon personally. Noting that Gori is the pack leader, Jachi gives the titan ten seconds to attack him with everything he has while promising not to move an inch. Enraged at Jachi's defiance, Gori launches a barrage of attacks. To the titan's shock, Jachi is completely uninjured. Jachi once again expresses disappointment, for he had been looking forward to seeing what foes from another world could accomplish. The demon jumps up and strikes Gori across the face. The blow sends the titan flying several kilometers away, killing him in an instant.^[3]

The titan's corpse lands in front of the Madalan, Uki. Jachi flies to the location and notes the corpses of hundreds of demons scattered all across the battlefield, including Kiva. Jachi asks Uki if it was responsible for the devastation, also noting that Hallow had been there recently and wondering where he and the other humans went. Uki refuses to answer and attempts to kill Jachi. The demon is unharmed and assumes Uki was the one responsible for slaughtering the demons. Jachi rushes toward the Madalan, demanding the foreign creature know his place, before the two battle. Jachi endures several of Uki's strongest attacks to measure its strength before retaliating with an uppercut. Jachi notes the Madalan lacks mana despite utilizing attacks that appear like magic. With his curiosity piqued, Jachi demands Uki show him more. Jachi and Uki once again exchange blows, though Jachi quickly overpowers his opponent. Realizing Jachi was superior in strength, Uki initiates its transformation into its Space Plate: Shinra form.^[4]

Uki uses a gravity distortion technique to generate a miniature singularity to pull Jachi in before using space distortion to pummel Jachi with a barrage of high-speed attacks. Uki then throws the singularity at Jachi, causing the demon to sink into the ground, before it summons space monsters from its body to rip Jachi's body apart. To the Madalan's surprise, Jachi emerges from the ground relatively unscathed. The demon admits Uki's attacks weren't bad and tells the Madalan not to let him down. Jachi removes his armor that had been siphoning his magic, allowing Jachi to unleash his full power.^[5] Uki attempts to push Jachi away with its technique, though Jachi takes a deep breath to pull Uki inward and imitate the gravity distortion technique the Madalan used before. Jachi clenches both his fists together and slams the Madalan into the ground, critically injuring it. Realizing Jachi is too strong, Uki attempts to flee and call the other Madalans for backup. However, Jachi easily catches up with Uki and slams his fist into the alien's stomach before following up with a jab across the face, sending it crashing downward. His attacks severely damage Uki, causing the Madalan to revert to its original state as it crawls on the ground. Jachi mocks the Madalan by asking how it's going to survive his next attacks. He mimics Uki's previous high-speed attacks and pummels the alien into submission as another act of mockery. As Jachi stands over the defeated Madalan, he notes that Uki wasn't alone when the demon army was slaughtered, meaning there were more foreign lifeforms roaming the planet. Jachi smiles as he expresses how interesting things have gotten.^[6]

Suddenly, Uki reforms its body and transforms into its Space Plate: Brawns form to battle Jachi. But before their battle can resume, a fist barrels its way through Uki's chest from behind, destroying the alien's body again. Jachi expresses mild surprise at Uki's death and the enemy who killed it. Ginbak, the chief of the Titans, questions if Jachi was the one who killed Gori. The demon instantly senses Ginbak's immense power and recognizes him as an enemy that must be taken seriously, preparing to battle the titan.^[7]

He admits to killing Gori, prompting Ginbak to first burst into tears and mourn his son. However, his grief quickly turns to rage, and he stomps on Gori's body in anger. Jachi confronts the chief of the titan warriors, declaring that if Ginbak seeks revenge, his battle is with him. Ginbak accepts the challenge and strikes Jachi with a blow that sends him flying. Jachi regains control mid-air and retaliates, but his attack has no effect on the titan. Ginbak lands another, more powerful blow, launching Jachi far away from the battlefield.

Jachi realizes he has lost control of his flying magic and is unable to stop himself. He crashes into the Mecha Ordinance buildings and eventually lands in a canyon. Determined, he activates his Release, which results in unleashing an oppressive aura that suffocates Ginbak's followers. Jachi quickly flies back toward Ginbak but is interrupted by a telepathic message from Nyudo. Nyudo uses the Grand Teleportation Magic Circle to relocate the group of titans. Frustrated, Jachi tells Nyudo to stop, but the demon lord ignores him and completes the spell, teleporting the titans away before Jachi can land a punch.

When Jachi demands to know where the titans were sent, Nyudo reveals that he transported them to the castle of the 23rd Demon Lord, Diganazal. Jachi is angry about this, but Nyudo warns him to be more cautious when choosing his opponents. Reflecting on the situation, Jachi surveys the remnants of the battle and senses the lingering magical energy of a teleportation spell used previously by the humans. Believing the hero Hallow may have survived, Jachi retrieves his mana-draining armor cape and decides to follow the magical mana trail.^[8]

Abilities

As one of the 47 Demon Lords, Jachi is an incredibly strong warrior. He could casually disperse Regis' strongest flame attack with a breath and killed the wizard with a mere flick of his earwax. Moreover, he could withstand a direct blow from the Sword of Courage in spite of its ability to damage Demons and casually overpowered Hallow. His incredible strength would be seen again, when he casually defeated the Titan Crown's Brother Gori and overpowered the Madalan Uki in his regular state. Jachi's strength forced Uki to activate his Space Plate: Shinra transformation in order to match him. After removing his armor which siphoned his magic, he easily outmatched Uki and brought the Madalan to a near-death state. Jachi could withstand casual punches from Ginbak and seemed confident in fighting the Titan Chief in his Release state.

Physical Abilities

• Superhuman Strength: Jachi wields enormous physical strength as a demon; by merely flicking a speck of earwax he is able to split a human in half and crush the wall behind them with the force of the impact.^[9] Even Hallow's honed swordsmanship meant nothing, as Jachi casually caught the sword with fingers before effortlessly ripping the hero's arm off in an instant. Furthermore, a single casual punch from Jachi is enough to send the massive Titan Gori flying away for several kilometers. Jachi's strength proved greater than Uki's regular form given how he cracked the Madalan's head with his punch. After removing his armor, Jachi's strength increased, allowing him to grievously damage Space Plate: Shinra Uki with only a few punches.^[10][11]
• Superhuman Speed: Jachi boasts tremendous speed in conjunction with his strength. He easily caught Hallow's sword and ripped off the hero's arm before he even registered it. In his fight against Uki, Jachi could match the Madalan's speed. Once Jachi removed his armor, his speed increased. When Uki sped away in his attempt to flee, Jachi caught up to the Madalan and traversed the large distance within a moment. Jachi could also replicate Uki's high speed punches with nothing but his own physical prowess, whereas Uki required his spacial manipulation to use such a barrage attack.
• Supernatural Breath: Jachi's breath is so powerful that merely exhaling was strong enough to disperse an enormous fireball before it could reach him.^[12] Jachi's breath was also powerful enough that his inhale could pull Uki toward him despite the Madalan being hundreds of feet in the air.^[13]
• Supernatural Agility: Despite his enormous size, Jachi can move swiftly and with great agility as he dodged many of Hallow's attacks with grace.^[14]
• Supernatural Durability: Jachi can endure strong hits with the Sword of Courage, a holy sword that is said to be able to deal damage against Demons.^[15] Even the strongest attacks of the Madalan Uki only left Jachi amused. Jachi withstood one of Ginbak's more serious punches with only light injuries.

Magical Abilities

• Dense Magic: His dense magic can kill other living beings nearby, like most of Hallow's party.^[9]
• Flight: Jachi can fly by using magic.^[16] He is seen flying while traveling outside of his castle,^[17] capable of reaching high speeds to traverse terrain as seen when he followed up on the defeated Titan Gori.^[18] However, he can lose control of his flying magic if he is blown away at sufficiently high speeds.^[16]
• Magic Detection: Like most demons, Jachi can sense magic. He detected the lingering mana left behind by the humans when they cast their teleportation spell.^[19]

Techniques

• Release: Jachi partially unleashes his true power, causing glowing lines to appear on his skin while his body is covered with spiked armor.^[20]

Equipment

• Mana-Draining Armor: Jachi dons a set of armor that siphons his mana in order to limit his power. Once he removes the armor, Jachi's abilities increase exponentially, allowing him to easily dominate Uki, an opponent who could fight on even ground with him before.

Trivia

• His name is taken from orca in Japanese (シャチ, shachi).
