Izayoi Sakamaki

Izayoi Sakamaki is one of the main protagonist of the Mondaiji tachi ga Isekai Kara Kuru So Desu Yo? anime and manga.

Izayoi is a young teenage boy and currently one of the leading members of the [No Name] community.

Appearance
Izayoi has light blonde hair which spikes downwards in all directions, and a set of purple eyes. He wears a pair of white headphones with black straps and a flame logo on each side. He has stated that he wears them to keep his hair down, but it is revealed later he most likely wears them because of a promise he made with Homura while still back in his own world. He wears a dark blue gakuran and keeps only one button in place. The rest are unbuttoned to reveal a yellow undershirt beneath the uniform. Izayoi also wears pants of the same color, and a pair of tennis shoes with black, white and gold tones.

In Volume 3 of the light novel, his headphones were stolen by Calico Cat, then through a series of unfortunate circumstances, destroyed in the Underwood story Arc; coincidentally, this is where his gakuran was also torn in battle, and later made into makeshift bandages for Gry when the latter was injured. Hence, after the Underwood arc, Izayoi underwent a major wardrobe change, consisting of a yellow shirt under a red zip vest and a black jacket. He wears gray pants in place of his old ones and he is still seen wearing his old tennis shoes for footwear.

Starting Volume 11, Izayoi wore a plain black shirt, khaki trousers and brown boots after his outfit is ruined during his fight with Azi Dakaha. On the cover art of Volume 11, Izayoi is also seen with the nekomimi headphones Yosummoned back in the Underwood arc with the intention to give to Izayoi as a replacement for his destroyed ones, but never had the chance to.

Volume 12 has Izayoi return to his previous appearance, though during a Gift game he wore miner's equipment.

Personality
Izayoi is a very unpredictable (quoted from himself) young man who likes to use his clever mind and impressive strength to solve everything and appreciates a good fight. He easily described himself as vulgar, savage and a hopeless hedonist, which makes sense as he can be fairly perverted as seen by his comments with Black Rabbit, making jokes about her body and wanting to claim her virginity. Be it a Gift Game or a simple cooking contest, such as in the side story, Lily's Big Adventure, he only participates in things that are deemed interesting to him. He enjoys challenges and will even participate in a Game with a handicap so long as it makes the Game more enjoyable.

Despite his outer appearance and frivolous personality, Izayoi is surprisingly highly intelligent, having solved the riddles to all the Gift Games presented in both the Anime and Light Novels and showing an in-depth knowledge about a myriad of subjects, ranging from mythologies, scientific concepts to architectures. He mostly spends his time in a library reading when there are no Gift games going on, showing his studious (bookworm-ish?) nature. He is also shown to be a forgiving person so long as the guilty party is conscious of what they have done and show guilt while being forthright about it. Though, this might just be attributed to his hedonism and his lack of interest in anything not interesting. Though even Izayoi is shown to be a rather sore loser, as shown when Izayoi and Black Rabbit's Gift Game ended in a draw. Izayoi's dislike of losing is also shown in the cooking contest that he lost to Yo. While he did acknowledge her as being the better of the two, the young man began to practice with a recipe he learned and continued to do so until he could challenge her again as he could not stand being second best to Yo.

Izayoi's arrogance does not falter but he knows when to back down in a fight, as shown in Episode 2 where he conceded defeat to Shiroyasha, showing his confidence is not just arrogance. One of his more surprising traits is his loyalty and care for the Community. At first apparently joining for the fun of it, he showed a caring nature for the people within the group and constantly makes plans to improve both the group and its reputation. During the Alliance Flag arc, when he saw Black Rabbit heavily injured by the hands of His Highness, he flew into a degree of rage that not even his friends have seen before, abandoning all his self-restraints and forcing all his friends to retreat from the area since they would have been caught in the fight as well.

In the end, Izayoi is the type to follow his own rules and morals, which includes such lines as "Trample both the strong and the weak." Following this, he is merciless to whomever his opponent is, whether it be a god, comrade, or Demon Lord. His constant search for enjoyment is seen as problem-causing, but the charisma he wields is enough to draw people to him to follow. He will not forgive anyone who goes against what he believes; during the Alliance Flag arc, when he heard of the details about the Kamikakushi cases happening in Kouen City from Mandra and especially how the criminal only targets young children, he immediately decided to voluntarily assist in the capture of said criminal as one of his morals is "A strong power should be used only against a strong opponent." However, because he knows how different his abilities are from the others, he feels that he has no one to depend on and thus often taking on all the burdens himself.

His only rule and main goal in Little Garden is "to have fun."

Gifts
Code: Unknown - Not much is known about his ability as the Gift Card, a fragment of Laplace, could not categorize his ability and so named it [Code: Unknown]. Despite this, he seems to know his power well, being able to gauge whether or not he can take an opponent. He can defeat those blessed with [Divinity] such as a water god and Weser, deflect a lance attack from the weakened Leticia, stop a sword attack from Laius, who is a descendant of the hero Perseus, with one finger and defeat the Kraken and Graea sisters, monsters that appeared in the legend of Perseus, with ease. Many people who have seen him fight have realized that his power is capable of destroying gifts. Black Rabbit also stated that his gift has the power to destroy heaven and earth, and later with a statement by Baron that it could even destroy the stars. This is shown during his battle with Algol and Black Percher, where he easily deflected their attacks. The force he emits behind his strength and speed is described in the Light Novels to be of the Third Cosmic Velocity or even faster than that.

Canaria stated that if his gift were to be given a name, it would be [Last Future of Embryo].

It is revealed that the gift Izayoi possesses is the Third Perpetual Motion Machine in the form of nano machines sealed inside his body.
 * Supernatural Strength: This seems to be the main function of Izayoi's Gift as it grants him immense strength. He uses his strength to throw objects at the 'Third Cosmic Velocity', run on walls by digging his feet into them, and even compress Leticia's lance into a ball by simply punching it. Back when Izayoi fought Baron La Croix before he got summoned to Little Garden, Izayoi could lift the entire building and throw it at him with no effort. In Volume 4, Izayoi easily defeated an army of Celtic Titan. Izayoi also could keep up with Saurian Demon King in Volume 5, as both of them neatly matched against each other though it was quite difficult for Izayoi because at that time he still didn't have martial art skills. When Izayoi knew His Highness was the one that injured Black Rabbit, in anger he beated him so violently that His Highness couldn't protect himself for a moment before his company came to save him. In Volume 7 both Izayoi and His Highness got a re-match at the Kouen City, His Highness admitted that Izayoi were stronger than him even though that Izayoi didn't feel any different from the powers of their fists. The punches of Izayoi were strong enough to destroy mountains and rivers, split the oceans or seas, on par with planetary crustal movement and even shake the stars. As seen in Volume 8 when he thrown hundred of punches which could shake stars on Azi Dahaka at the Third Cosmic Velocity, thus overwhelmed him for a short amount of time before he put up his Aurora Pillar.

Sun Authority: Leo: A Sun Authority stated to be the power of the Fifth Western Zodiac, Leo. Leo's power is based on the myth of the Nemean Lion, a beast who was completely impenetrable to blades. This protection was grated to Izayoi and blessed him with the same defense against blades, thus making it possible for Izayoi to safely catch the Spear of Indra and throw it back. In Last Embryo 1, the Minotaur attacked Izayoi with Proto Keravnos but he was completely unharmed despite that a single strike from Proto Keravnos can surpass the concept of "slash". However, this Sun Authority is not effective against destruction Gifts which contained Gifts of stars or Gifts that could slay the Celestial Spirits, as seen in volume 12 when Laius successfully slashed Izayoi by his Harpe, though Izayoi weakened his attack and only received a small injury.
 * Enhanced Perception: Izayoi possesses an exceptional sixth sense, easily signaled out Fores Garo's henchman in Episode 3 and Leticia's presence when she was hiding outside the window in Episode 4.
 * Supernatural Speed: His speed is said to be on par with Black Rabbit, who is mentioned to be part of the fastest species in Little Garden. However, his speed is different from hers as he is able to retain that speed as shown when he blocked an attack meant for Black Rabbit, returned her safely to a rooftop and proceeded to return to fight Black Percher. He was fast enough to leaves his afterimages, as seen in volume 5 when battling the Saurian Demon King and in volume 6, when chasing the Demon King of Confusion at Kouen City. If Izayoi were to put his full strength behind his every step, the residential structures that weren’t stable enough would most likely be blown away.
 * Supernatural Durability: Izayoi has been shown to be rather durable, being the only one out of the three problem children to not need a Gift of Protection to survive his fights and take on powerful attacks without being injured. It took Weser with double his power and possessing [Divinity] to only injure Izayoi and even then the injury did not even slow Izayoi down. However, his durability isn`t invincibile, he's shown to be rather weak against bladed weapons wielded by a strong enough individual, and he suffered quite a bit during his fight against Saurian Demon King. In his battle with Azi Dakaha, Izayoi was stabbed through his abdomen and had his organs punctured. It should be noticed that when Izayoi's Aurora Pillar made contact with Azi Dahaka's [Avesta], he barely survived the force of impact, though Azi Dahaka later explained that their powers canceled each other out so that Izayoi could survive the blast. After his fight against Azi Dahaka, all the bones and the muscles in his body were minced.
 * Supernatural Stamina: During the fight with Azi Dahaka, although Izayoi received a lot of injuries and therefore his stamina almost ran out after the fight with His Highness, he was still able to fight with every bone and muscle in his body almost completely chopped up and crushed. Izayoi was the first one that held back Azi Dahaka for the others to run away even though he was already on the verge of his death.
 * Supernatural resistance: Based on his ability that allow him to negate and destroy Gifts, Izayoi has resistance to supernatural powers. Several examples include when Izayoi was totally immune to Ratten's mind control music in volume 2, Baron placed a Death Curse on Izayoi but it never took hold on him in volume 3, and when Demon King of Confusion stopped time in all of Kouen City and its residents, but Izayoi was completely unaffected in volume 6.
 * Aurora Pillar - A power that revolves around creating a light construct in the shape of a small pillar which then enlarges to the point of reaching skyward, he then swings it at his enemy. This is the true manifestation of Izayoi's power to destroy Gifts. Its power could defeat Divine Spirits, eliminate all of the stars in the night sky and annihilate everything in the material world. He has used it for four times: to destroy the pocket dimension Baron La Croix created, to destroy the huge dragon's heart, in his fight against Azi Dakaha - when the Aurora Pillar made contact with the [Avesta] created a vortex with power comparable to the collison between stars that could destroy All Creation and their clash reduced more than half of a volcano peak to nothing more than subatomic particles, the force unleashed from Aurora Pillar capable of absorbing the light of the stars and pierce through the veil of Little Garden, and finally in Volume 11 with the help from Baron La Croix, he erased Maxwell Demon Lord by his Aurora Pillar with only one shot. His Highnessdescribed it as a "Another Cosmology", the secret techniques of the pantheons of Gods to construct their own worlds - universes. Izayoi also made a compliment by himself that his Aurora Pillar is shape of a possessing cosmology of humanity. It has been hinted from Volume 2 when Izayoi managed to unleash his full power against Black Percher after she mocked Izayoi that he didn't have enough strength to destroy stars but Black Rabbit stopped him due to the plan and in Volume 5, during the fight between him and Saurian Demon King that if Izayoi used this trumpcard, he would not be able to control it enough to let Saurian survive the hit, it also should be noted that when Izayoi put up his Aurora Pillar even Azi Dahakagot shocked after saw it and he had to activated his [Avesta] to counter him, making the Aurora Pillar is extremely powerful and very dangerous even for the strong Demon Lords. Only the like of His Highness or Azi Dahaka in which they also possessed "Another Cosmology" like Izayoi could match against his Aurora Pillar.

Grass Bracelet - A bracelet made of grass. It gives the owner the ability to talk to griffins. Sala gave this to Izayoi to let him communicate with Gry during the assault upon the huge dragon in the Underwood arc.

Natural Abilities
Keen Intellect: Izayoi is incredibly intelligent. He has created plans to help the No Names in both battle and commerce. Izayoi has shown that he is knowledgeable in religions, fairy tales and mythologies, having easily identified the [Perseus] artifacts, solved the riddle of the Pied Piper of Hamlin, and identified constellations and asterims. When Izayoi is left behind to stall for time against Azi Dakaha, Asuka remarked that without him, they cannot even come up with a proper plan of attack.

Hand-to-Hand Combat: It has been stated that Izayoi is a very competent fighter and also has amazing reflexes and potential. Saurian Demon King once remarked that Izayoi had the potential to be an experienced martial artist with his skills. In Last Embryo 2, when Bull Demon King managed to smash Izayoi with a pole, Izayoi immediately blocked and kicked it off his hands timely. Izayoi also had shown an arm-locking technique when he tried to pin Bull Demon King to the ground and in near the end of the fight, he threw Bull Demon King away by grabbed his horns, making him crashed into several maze wall layers, Bull Demon King remarked that he didn't expect Izayoi finally got some martial art skills. Up to now it's still unknown how Izayoi got them after 3 years of timeskip but its implied Kouryuu may have taught him.
