Haruyoshi, who is the strongest onmyōji (diviner) in his world. He's betrayed by his friends and, on the verge of death, he wishes to be happy in his next life. He then attempts a secret reincarnation spell. The spell is a success and he is reincarnated, but somehow it's in another world. He is reborn into a distinguished family of wizards, but is judged to have no magical ability. He soon realizes however that the magic in this world is nothing compared to his old onmyōdo arts, and he declares that he doesn't need magic. He thus begins his easy life in another world with his onmyōdo arts and a multitude of yōkai creatures who follow him.

Now reincarnated as Seika Lamprogue by the "*Curse of Reincarnation*" that he devised. He doesn't have the magic that is widely used in other worlds, but he has the wisdom of when he was an onmyōji, as well as abundant magical powers. During his lifetime, he was murdered for fear of his mighty power, so he tries to live "*inconspicuously and cunningly*" to seize happiness.

Seika's appearance in her previous life, a man who was touted as the strongest onmyōji of all time. He greedily sought power without caring about his surroundings. He had a gentle side, such as taking an orphan as his disciple and loving Yuki, who lacked ability as a ghost, but his excessive power was seen as dangerous, and he was defeated by his beloved disciple due to the Imperial Court's conspiracy.

Seika Lamprogue (Haruyoshi) is the most powerful master of **Onmyōdo**, or Japanese magic. He doesn't have the magical powers that are widely used in other worlds, but he has the wisdom of traditional Japanese esoteric cosmology, a mixture of natural science and occultism. It is a very eclectic blend, including Wu Xing and Godai (*Five Elements*), Yin and Yang, shikigami (cursed spirits), and divination to ofuda and alchemy. Because of being a master of spiritual arts, his spiritual forces are larger than a normal human or A-rank Mage has a decent in magic power.

* Onmyōdō (meaning "The Way of Yin and Yang") is Japanese-style spell-casting. Methods range from Yin/Yang, Five Elements, Shikigami, and *Divination* to *O-Fuda* and *Alchemy*. *Onmyodo* is a very eclectic blend; while it can be treated as simply *Rule Magic*, it also has elements of *Force Magic* and *Theurgy*.
* Onmyō Arts is activated by reciting mantra, consuming its own spiritual power using paper doll (Shikigami) as a catalyst, it's very similar to the [magic] that people in this world consume when activating their own magical power.
* ***Gobosei*** (pentagram) In Japanese culture, this is a symbol of magical power, associated with Abe no Seimei; it is a diagram of the "*overcoming cycle*" of the five Chinese elements (*Wu Xing*).
* **Kuji-In** and **Kuji-kiri** (*The Nine Syllable Seals* and *the Nine Symbolic Cuts*), are also among Onmyodo techniques, though they were never unique to Onmyodo.
* ***Eastern Zodiac***, One of the divination means *Onmyoji* employed. During the Heian era, *Onmyoji* was also responsible for making calendars. As part of that system, The Four Gods were thus also incorporated into Onmyodo. and Feng Shui (*fortune telling*), Another Chinese influence amalgamated into Onmyodo.

**Shikigami**, in traditional Japanese folklore, are either invisible or appear in the shape of neatly-folded paper manikins. However, in the film's adaptation, the Shikigami are portrayed as fully-visible, semi-humanoid paper creatures with the ability to fly at extremely high speeds (on par with Haku in his dragon form). They are white in color and resemble birds and have a circular head, wings, and a pointed "tail". When magically commanded, they can stand (or hover) on the tip of their tails and plaster themselves onto a person's body. The paper doll (*Shikagami*) is also used as a boost to the user's physical/senses or even cast an instant evasion even teleportation to another place.

* *Shikigami* are conjured beings, made alive through a complex conjuring ceremony. Their power is connected to the spiritual force of their master, where if the invoker is well introduced and has much experience, their *shiki* can possess animals and even people and manipulate them, but if the invoker is careless, their *shikigami* may get out of control in time, gaining its own will and consciousness and can even raid its own master and kill them in revenge. Usually, *shikigami* are conjured to exercise risky orders for their masters, such as spying, stealing, and enemy tracking. *Shikigami* is said to be invisible most of the time, but they can be made visible by binding them into small, folded, and artfully cut paper manikins. There are also *shikigami* that can show themselves as animals.
* *Shikigami* is a form of weapon utilized by spiritualists and Onmyoji. The basic concept behind Shikigami is summoning a spirit into a vessel, and it is common for one to use paper dolls. It is also possible for one to summon them into the body of a person or animal, though this is risky as this gives the Shikigami greater power, and with power the risk of rebellion. They have a variety of uses, and can also be treated as soldiers or minions instead of weapons. Most of the time, Shikigami are invisible to the eye, so they can be used for spying or assassination. Those who wield Shikigami are considered supporters, as the wielders themselves typically don't do much fighting, with the exception being Onmyoji. Keeping Shikigami wielders in the back will be quite helpful, as the summoned Shikigami can assume more humanoid forms and fight alongside the main combatants. This also means that a wielder can do just fine on their own, assuming that they have Shikigami fighting for them.

Seika also uses Jutsu which deals with the power of curses. It doesn't have a specific name for its technique, but it does scary things from time to time. Seika beat up his brother who always gets involved. He just crumpled the arms of the human-shaped curse, and his brother held his arms and fell down. What's more, it's just a pain, and it's not actually broken. This means that you can inflict only pain as long as you like, forever.

Furthermore, he also managed to repel the magic that the enemy used. Rather, for Seika, who used to be an Onmyoji, this might be her specialty in completing the Condition. Specifically, when the condition has been met the act of pouring demon blood/Ordinary blood on itself in front of the enemy's caster, becoming cursed, and returning the curse by incantation the mantra. There shouldn't be any need to go out of your way to do that in front of the caster, but I think it's quite an inciting attribute to do it.

Well, actually, I thought I would ask various things from the caster, so I dared to appear in front of the caster's eyes. And the caster who was cursed back vomited blood and fell down and died as it was. It's a moment. If you ask him what he wants to know, he will easily kill him. Seika said to him that his not good at swordsmanship.
