Keiichi Haven

"Blaine. Thank you. Our adventures were truly fun, weren't they? I guess it really has been... a roundabout path."

- Keiichi Haven

Keiichi Haven (ケイイチ・ヘイブン) is the protagonist of Rising Beginnings and Advanced Battle. He returns in Evolution Evangelion as one of Sol and Mizuki's primary allies. This is the original depiction of Kierian Haven, as created by Alex Guy.

He appears prominently in Stardust Frontier, Evolution Evangelion, Stardust Requiem, and briefly in Regional Crusaders, and Final Endings. He is the original central character in the Evershade series and the most popular and recurring protagonist.

Keiichi is introduced as a young delinquent with a heart of gold, living in the woods with his best friends Chloe and Blaine. Believing that he was not strong enough to save his parents, Keiichi traveled across the Easton region in order to become the best, becoming rivals with Azure.

After being antagonized by the Chaos Agency, he sought tutelage under Master Crimson, learning and developing powerful magic skills in order to fight the Chaos Agency more effectively.

Upon the defeat of the Agency, Keiichi's group was recruited by Division X and its leader Ezekiel Connolly, quickly befriending agents Russell Johnson and Xander Summers. Joined by Russell and Xander, Keiichi battled evil mutants and the dangerous gang, the Alliance.

With Division X's exposal, the team defeated Xeno and went their separate ways, with Keiichi disappearing from society, unlocking demon magic within him, and fathering a child whom he never knew about. One a decade later, Keiichi returned to civilization, participating in the new Grand Championship, during which he gained the Meta Ability dubbed "First Blood," and traveling to the Alohe region to find his long-lost twin sister, Kimiko Haven.

Using his demon magic, he assisted Sol and Mizuki against a threat from his past: the Evolutionary, successfully rescuing his sister and avenging his parents by defeating its leader, Demora.

Following another Grand Championship, Keiichi once again disappeared from society, settling in Alkali Mountain for seventy years, until briefly returning to aid Axel, Serena, and his grandson Sebastian Rhodes in the last stand against Azazel and Reign.

Appearance
Keiichi is canonically established as a tall (186 cm/6'1"), attractive, fair-skinned, and well-built man, even for a young adult. He has short and unkempt silver-white hair, which darkens to gray as it lengthens to the nape of his neck, a strong jaw, bold eyebrows, and piercing red eyes, which are drawn to look menacing. He bears a small scar over his right eye and a mole on his right cheek, and various characters have described Keiichi to be stone-faced. He also closely resembles his father, Benjamin Haven.

The superficial theme of Keiichi's attire experiences minor changes in his later appearances. His trademarks are a dark gold bandana, gloves studded at the knuckles, fitting black pants, knee-high futuristic-looking boots, and an unbuttoned long white coat, roughly mid-calf-length, and featuring a raised studded collar, with a black t-shirt underneath though the color later changes to navy blue. His attire was influenced by Jotaro Kujo from JoJo's Bizarre Adventure, and Seto Kaiba's outfit from the Battle City arc in the original Yu-Gi-Oh! series.

Personality
Keiichi is introduced as a rough and bitter delinquent due to his upbringing and guilt over his parents' deaths, which inspires him to set out and become stronger. Despite this, he has a gentle heart, showing compassion, morality, and loyalty to those he likes but not to individuals who have not earned his respect such as when he ruthlessly kills a criminal instead of giving him mercy. As the series continues, Keiichi undergoes a change in personality, becoming a calmer and kinder person, who only shows extreme anger and arrogance during battles with cold villains, or in extreme situations, such as the death of a friend or relative.

Mainly during the beginning of the series, he tended not to give respect to people of higher authority, such as "Ezekiel Connolly" and the mayor, and does not seem to be too scared of beings like Xeno, Demora, Azazel, and Reign, and is especially cruel to Dakera despite the latter's lack of care towards Keiichi's insults. Throughout the series, Keiichi is shown to be perceptive, intelligent and often quick-witted while keeping a perpetually cool, slightly neutral or disinterested attitude.

Early Life (1996-2016)
Keiichi was born the son of Ben Haven and Mirai Haven, two scientists working under the Evolutionary. As a result of genetic engineering, Keiichi developed dormant demonic abilities, however, he grew to despise his environment. This would influence his behavior later in life.

The Journey Begins
Several years later, 21-year-old Keiichi was a known delinquent living in East City.

Thunder City Tournament
During his battle against the Alliance, Keiichi noticed an advertisement for the Thunder City Tournament. Shortly after the fall of Division X, both he and Azure entered the tournament and progressed to the finals, in which Azure was defeated by Keiichi in the finals. Afterward, however, he left and gave the champion position to Azure. This tournament specifically would go on to influence Ruby and Sapphire decision to enter the tournament.

Lone Wolf / Disappearance
At some point in 2022, he traveled to the Corona region about six months before Aurea and Crystal's adventures to become stronger on his own. Unbeknownst to him at the time, he had dormant psychic powers that were the result of the demonic cells inside of him, thanks to the Evolutionary. During his stay, he briefly researched the Gold Orbs and discovered their connection with Vessel.

However, his presence caught the attention of Shirogane, who sensed the demonic powers inside of Keiichi and convinced her that she needed the Gold Orbs to combat this demonic power in case anyone used it against her. Keiichi was mentioned to have disappeared from civilization by 2022. This would lead to several events, such as Azure abandoning his position as Thunder City champion to find him, Dakera kidnapping Chloe and Blaine instead of Keiichi, the battles on Kingdom Island, and the awakening of several mythical beasts.

After the destruction of Kingdom Island, Chloe began to look for Keiichi after Azure was turned to stone. His whereabouts during these events are unknown but sometime in 2027, he had conceived a child with an unnamed woman and was not made aware of this. He had also stolen the Time Stone from the Eight Precepts of Death, and settled at the summit of Emerald Mountain to train his newly developed powers.

Discovery
Like the rest of the world, Chloe had lost all contact and knowledge of Keiichi's whereabouts and teamed up with Kyotaro and Russell to find him. Eventually, the three reached the top of Emerald Mountain and found Keiichi, who agreed to head back with them. Using his psychic powers, he unlocked the Time Stone and restored Azure from his stone state but left Dakera alone, and quickly disappeared once again.

Return to Civilization
Because of the news of the Nova region's Grand Championship, Keiichi decided to participate. This marked the first major appearance within society since 2020.

Discovery of his Sister
In 2033, Keiichi decided to travel to the Alohe region's Ocean City upon the request of Russell. Russell, while doing research, discovered that Keiichi had a twin sister named Kimiko Haven.

Legend of Alkali Mountain
By the year 2111, all of Keiichi's friends and allies, save for Chloe, have died of natural causes, and due to their accelerated healing factor, they are still alive. Unfortunately, Keiichi remained unaware of his son and grandson, Paxton Young.

Paxton informs Axel of the legend of Alkali Mountain, which tells of a man who does not lose, causing Axel to head off in order to find the man, desperate to stop Azazel's growing threat. Eventually, it is revealed that Keiichi is the one described in the legend, however, he refuses to help against Azazel in fear of destroying the entire region with his demonic powers.

Climactic Return
In the climax, Keiichi arrives on the battlefield and easily defeats Azazel, motivated by Axel and Serena's words. After Azazel's death, Reign arrives and shows off his new power against Keiichi, giving the latter a difficult fight until Keiichi begins to feed off of everyone's fear and despair, supercharging himself with demon energy and regaining his lost power, while also gathering Genki from Axel and Serena and putting all of it into a single punch that kills Reign. He quickly reunites with Chloe before departing for Europe, promising to return.

Xeno Offensive
In an alternate, erased future, Xeno, after killing his creator, went on a rampage across the country and eventually crossed paths with Keiichi. The two engaged in a drawn-out battle until Keiichi finally used the Time Stone to send Xeno back to 2017, creating an alternate timeline.

Overall Abilities

 * Immense Strength: Keiichi's most distinguishable trait is his unnatural levels of strength. Five punches from Keiichi could disorient a rampaging mutant. Despite this, his strength was not overly impressive and gradually increased. However, after awakening his demon powers, Keiichi's physical abilities increased dramatically, giving him the strength to completely destroy several blocks from the wind pressure his punches make. Despite becoming weakened when first meeting Axel, Keiichi's strength was such that he was able to challenge and overpower even seasoned soldiers such as Reign, who he was able to kill off in their battle. He clashed with Reign's attacks and canceled out their highly destructive power with brute strength alone.
 * Super Jumping/Leaping: He is able to jump several feet off the ground and leap several stories in a single bound without having to fly.
 * Immense Speed: In conjunction with his high level of physical strength, Keiichi possesses an equally impressive amount of speed. When he arrived at Ultimate City, he moved a remarkable distance and simultaneously incapacitated villains in the blink of an eye. Axel and Serena even say that they were completely unable to track his movements despite the latter being slower than he once was. However, according to Keiichi himself, he is slower than he was seventy years ago.
 * Immense Durability: With his cells enhanced by the Evolutionary's super-soldier serum, Keiichi's bodily durability is considerably stronger than even the densest of Earth's metals such as steel. He sustained no life-threatening damage from his battle with Dakera and the Alliance's various mutants and took point-blank, unrestrained explosions from Cyrus without so much as slowing down at all. Keiichi was even able to survive Demora's blast wave attack, a move that can cause city-wide catastrophic damage, although heavily injured.
 * Immense Stamina: In his prime years, it was noticed that Keiichi has never been shown to be tired even when fighting against multiple villains. The only time that Keiichi was shown to be panting and out of breath was against his battles with Dakera, demon scientist Demora, and Reign, and that was only due to either being weakened by the Chaos Agency's technology or his advanced age, which also limited Keiichi from using the maximum output of his demon abilities.
 * Expert-Master hand-to-hand combatant/Martial artist: Keiichi is proven to be a highly skilled hand-to-hand combatant and martial artist, as his combat skills are great enough to be able not only to fight on par against other very physically powerful experts of hand-to-hand combat and martial arts, but also to defeat them single-handedly, such as Demora, and even Reign, a very highly skilled demonic soldier in their altercation. His combat skills can even be still effectively used while he was in a weakened state or having deep hallucinations that made him not focused and much more brutal, as while weakened by the Chaos Agency's technology, Keiichi was still capable of fighting off a super-powered super soldier and defeating him, allowing him to escape with his friends. Keiichi is also one of the most, if not the deadliest combatant in the entire series.
 * Regenerative Healing Factor: Keiichi can heal and regenerate all physical and mental harm to himself instantly. Any damaged area will be completely restored with no lingering side effects in seconds, even forcing objects embedded out to heal properly. Keiichi can rapidly regenerate from almost anything such as gunshots to the head or body, stabbings, bombs, fire explosions, poisonings, among many other things. However, he is still capable of feeling pain and enough harm can render him unconscious.
 * Longevity: Keiichi's regenerative healing factor keeps him from aging beyond his physical prime, making him capable of living up to 115 years of age. However, in Final Endings, he was shown to have aged quite a bit but still looked 40 instead of 115. In addition to prolonging his life, his overall health, prowess, and condition remain at its peak.
 * Contaminant Immunity: Keiichi is virtually immune to all viruses, diseases, and most poisons or toxins. Only the most potent of chemicals will affect him and only for a brief period before returning to normal.
 * Trilingual: Keiichi is capable of fluently speaking English, Japanese, and Spanish.

Demon Magic
As a test subject for the Evolutionary, Keiichi was infused with demon-like cells and thus possesses great psychic and demonic power, however does not the same aptitude for it as Demora, since Keiichi is not a full demon. Despite his healing factor, which slows down his aging, these powers gradually weakened after 2029, due to Keiichi's discontinued training. By 2111, he had decreased in power due to his advanced age. However, his full power was temporarily restored during Axel and Serena's final battle with Azazel and Reign, by feeding off negative emotions like fear and despair from the sentient beings in his surroundings.
 * Transformation: Keiichi can transform between his human and demon forms at will, provided he has enough energy or magic. When running low, he automatically takes human form. When he regains his energy, Keiichi undergoes a drastic change in his physical appearance, gaining an extremely robust body, claws, and horns.
 * Hypnosis/Mind Control: He has the power to influence the wills of humans and animals, as well as gather information from their minds. This ability, though, has a limit.
 * Magical Combat: He was seen projecting powerful energy blasts and defending with shields against his opponents in the final battle with the Evolutionary. During his fight with the demon Demora, Keiichi combined dark magic and his augmented physical strength to perform a nuclear-scale finishing punch.
 * Telekinesis: Keiichi has telekinetic powers that allow him to manipulate objects. They are so strong, that they're capable of lifting half of a road highway and keeping it afloat for an extended period of time.
 * Teleportation: Keiichi is able to teleport with another person in tow, as shown when he used it to help Sol and Mizuki flee from Demora. The limitation, though, is that he is only able to teleport thirty feet away and continued use will eventually drain energy.
 * Forcefield Generation: He created one to protect him, Sol and Mizuki from Demora's barrage of energy bullets. In his demon form, he made individual shields for dozens of people to protect them from falling rubble.
 * Magic Transfer: Keiichi transferred magic to Mizuki in order to help her recover from her injuries, and later transferred his ability to smite demons and angels onto Mizuki and Sol.
 * Demonic Weaponry: He can summon various "demon weaponry", with his signature and favored combat weapon being a sword. During his fight with Demora, Keiichi was able to transform an ordinary broom into a great demonic sword using magic and used it to slice both Demora's arms in one blow, whilst destroying a quarter of Ocean City in the process.

Smiting
Main article: Smiting

Being half-demon, Keiichi possesses the ability to kill or exorcise other demons and beings simply by touching his palm to the forehead of its target. When this happens, a strong white light appears from the eyes and mouth of the victim and burns them from the inside out. He is revealed to have this ability in his final battle with Demora after unleashing his full demonic side, however, he passes this power through his "Magic Transfer" ability onto Sol and Mizuki, allowing them to smite Demora.

Trivia

 * Keiichi is of Japanese descent from his mother's side.
