Rudeus Greyrat

Rudeus Greyrat is the main protagonist of the series, who is the reincarnated NEET loser who died, the twist is that his memories of his past life remained. His current body possessed high affinity for magic even as a child.

Appearance
He is tall, well-built and cool-looking man. He was born with brown hair, but after his second encounter with Orsted his hair temporary became white. He also has slightly mismatched eyes because he switched one of his eyes for a demon eye. Like Paul, he also has a mole underneath his left eye.

Personality
He is extremely self-aware, because of his former life he is careful not to get carried away and become arrogant. He is afraid to revert to his old self.

He is kind, helps his friends and protects his family. He is capable in many fields and people have great expectations of him. Rudeus is very polite to others to the brink of making them uncomfortable.

He keeps his Japanese pacifist ways (doesn't want to kill anyone), however, he displays aggression and blood lust should anyone threaten his family.

He is extremely perverted. Even though he has this shortcomings, his family and friends still love him since he always takes care of them to a great extent.

Even with very high magic capacity and high potential in the battle, he often lacks the confidence to fight his enemy. He always tries not to be full of himself in anything.

Background
A 34-year-old NEET otaku who was chased out from his house by his family.

Just when he was at the point of regret, he saw a truck moving at a high speed with 3 high school students in its path. Mustering all his strength, he saves them but ended up getting run over by the truck which kills him.

The next time he opened his eyes, he was reincarnated to a world of sword and magic as Rudeus Greyrat. Born to a new world with a new life, Rudeus declared, "This time, I'll really live my life to the fullest with no regret!" Thus begins his journey.

『Voiceless Incantation』
Rudeus is one of the few people capable of using voiceless incantation, and even rarer as a person who can use voiceless incantation with melded magics. He cannot use voiceless incantation for healing magic. A normal Magician takes at least 5 seconds for a simple spell, for higher spells its 30-60 seconds. Rudeus can do it almost instantly no matter what difficulty of the spell, except for healing magic as only Sylphy can use voiceless incantation for healing magic.

『Demon Eyes: Foresight』
It's a Demon Eye that Kishirika gave to Rudeus for giving her food. It allows the user to see a certain amount into the future. But it is hard to adjust the focus point, the farther he look the more possibilities appear.

Certain experienced warriors can negate the Demon Eye's usefulness in battle by making the eye see multiple future versions to counter it like Ruijerd. Some beings like Badigadi are completely immune to the eye as it was unable to see him. The eye can also act as a conduit for another being's power as Hitogami was able to show Rudeus a vision of where to find his Aisha and Lilia through his eye. Another weakness of the eye is that it does not pick up sounds and as such, Gyes was able to incapacitate Rudeus using Howling magic.

Overuse of the eye, or a lack of control of it may cause the user some sort of pain and nausea. As Rudeus felt a moment of extreme nausea after Hitogami showed him a vision of the future; and when he originally received the eye it took him a while to learn to control it since it would give him double vision.

『Magic』
While Rudeus is a pacifist and doesn't like fighting in general, when he does, he is a formidable opponent. He is capable of casting multiple magics and mold them together. With his scientific knowledge from his previous life and creativity, he always strive for developing more efficient magics for himself to use. Most of the spells he uses a lot, like Rock Bullet, have been stated by Badigadi to have emperor level of power. Initially when he was a child he mostly used water magic getting his water magic to saint level however he eventually shifted to earth magic mainly relying on the spells Rock Bullet and Quagmire which gave him the title "Rudeus of the Quagmire". His total magical power has been stated by Orsted, Kishirika, Badigadi, and Pergius to be above Laplace. He was able to create a nuclear explosion in his fight against Orsted. Which at the time was the strongest attack magic he had used.

His rankings as a magician is as follows:
 * «Water Emperor Ranked»
 * «Earth Saint Ranked»
 * «Wind Saint Ranked»
 * «Fire Saint Ranked»
 * «Healing Magic - Saint Ranked»
 * «Detoxification Magic - Saint Ranked»
 * «Barrier Magic - Intermediate Ranked»

『Attack Magic』 =


 * -|『Healing Magic』

It is a unique magic that Rudeus copied off orsted in their first fight, it works by interfering with the magic of the opponent disturbing it and preventing it from working. this is a very rare and possibly difficult technique as Sylphiette a talented mage in her own right had a lot of trouble learning it. and had not heard of it either.
 * 『Ran Ma』- Disturb Magic

Dry Steaming is a melded magic of fire and wind originally developed by Rudeus to dry wet clothes with a risk of damaging a fabric.
 * 『Dry Steaming』

It is a variation of Stone Cannon originally developed by Rudeus. The stone is hollow thereby exploding at the point of contact.
 * 『Explosive Stone Cannon』

Realizing that 『Lightning』 might be a bit overkill as a single target spell, Rudeus tried to weaken the King-class Water magic. Rudeus was able to use Voiceless incantation to create a miniature thundercloud, compressing it, and designating a target for 『Lightning』. In order to distinguish it from the normal overpowered spell, he named it 『Electric』. The Electric strike is hard to avoid and can numb the nervous system, making it a very useful spell against people who can wear Touki.
 * 『Electric』

Rudeus can make a light spirit scroll to use them to summons bright light spirits as a source of light.
 * 『Light Spirits』

Howling is a type of magic that can locate or paralyze enemies by using sound as a medium, but Rudeus can only use it to surprise or scare opponents. He learned it from Gustav Dedorudia.
 * 『Howling Magic』

Fighting Style
Intermediate-ranked Sword-God Style
 * 『Sword Techniques』

Since Rudeus cannot make use of Touki, he cannot rise to Advanced ranked Sword Techniques.
 * 『Saint Dragon Touki』

It is a fighting style that was created by Dragon God Urupen, who was considered to be the weakest Dragon God due to having the lowest magical capacity ever and rose to become the strongest with this fighting style. It is a fighting style for defeating an opponent using a minimal amount of magical power. It is the greatest fighting style in the world. It is described as a fighting style by Rudeus that combines magic arts and martial arts [wushu] is a classic form of martial arts in his world. Rudeus is currently being taught how to use this fighting form by Orsted. He has been noted by others to be a battle genius. During his first fight with Paul, he was smart enough to trap Paul's leg to restrict them movements. During his time as an adventurer, he was known for his skill with Quagmire and trapping opponents with the earth magic before attacking. After training with Orsted, he became more aware of his tactics and was able to perform the strategies more efficiently since he was conscious of them. In the case that he is trapped by a high level barrier magic that restricts his magic, he will use the Manatite stone to destroy the seal and use a combination of Quagmire, Mist, and Electric to slow down or disable his opponents before using a summoning scroll to summon his trump card, the Magic armor MK I, to defeat his enemies should the need arise for the fire power. Taking stories and legends from his previous world, he was also able to come up with a strategy to defeat a hydra that could regenerate its heads.
 * Tactics

『Arrogant Water Dragon King』 (Aqua Heartia)
An expensive staff gifted to him by Eris on his 10th Birthday.

The material of the wand is made from a rough and bony wood that comes from a tree called 『Elder Torrent』, that grows in the large forest of the Eastern region of the Mills Continent. The Wand will become a subspecies after it drinks from the Faeries' Spring.The tip of the staff is adorned with a large Magical stone that is the size of a fist that comes from a stray dragon located in the Begaliid's continent. The maker is from the Asura's kingdom palace's Magic team, a wandmaker(Rod Director) called Chein Procyon. A wand's rank is determined by the wood and the Magic rock, both of which are A ranked materials. The Magic Stone alone is at least worth over 100 Asuran Gold Coins.

The wand has a lot of sentimental value to Rudeus, as Ruijerd was able to see how important it was to Rudeus and convince him to not sell it so that they could take Ruijerd to the Mills Continent the legal route; instead Ruijerd agreed to enlist the services of a smuggler even though they would be getting involved with people who would harm children, which is against Ruijerd's warrior code. Rudeus commonly calls it his friend and has a few nicknames for it. Although his power has out grown the staff's abilities, he will still occasionally use it during important battles. The Staff is normally kept in his room as a decoration.

『Mana Absorbing Stone』
A stone made from the Manatite Hydra's body. From Rudeus' testing of the stone, there is a front and back of the stone. When mana is applied to the back of the stone, a high pitched sound would ring out and the front of the stone will emit a magic canceling wave that is similar to 『Ran Ma』. The stone does not actually absorb mana and its magic breakdown power is similar to the Disturb Magic;however, the stone also requires an almost equal amount of magic power to negate attacking magic. Magically created objects like dolls that have their mana stabilized will not be destroyed by the waves, but magic attacks that do not have their magic stabilized will be destroyed. Magic Circles will not be destroyed by the stone, but the barriers created will. By inserting the stone into the 『Zariff's Prosthetic arm』, it can be an effective tool at the cost of magic less effective from that arm.

『Zariff's Prosthetic arm』
From Zanoba's research of the doll left by the previous owner of Rudeus' house, Zanoba with the help of Cliff were able to create an artificial prosthetic arm. With the chant, "『Oh Earth, become thine Arm.』", the magic tool can be activated, but with the chant 『Oh Arm, return to Earth』. It can also allow the wearer to feel tactile feedback from the fingers and even has the strength to restrain Zanoba's Miko Power. The arm can also fly out as a Rocket Punch. It was used as replacement of Rudeus' left arm that was lost in the fight against the Manatite Hydra and continued to function as a Rocket Punch gauntlet, after all of his limbs were restored by Orsted's King Class Healing Magic, until its capabilities were replaced by the second version black 『Magic Armor』.

『Dragon Tribe's Robe』
It is a grey robe worn by Great Sage Titiana 1,000 years ago. It is made of the Death Adder Rat's skin and was sewn together using a thread imbued with magic. It has considerable magic resistance and is highly blade proof. The weight of the wearer is reduced by half and it is possible to move like the wind. Rudeus received it from Orsted in volume 17 before going to Asura Kingdom to assist Ariel to become the queen.

『Dragon God's Armlet』
Its crest was engraved by Dragon God with the ability to block Hitogami's future foresight from seeing the future of the wearer. Orsted gave it to Rudeus after they started working together.

『Magic Armor』
An expansion of the 『Zariff's arm』 system, it is a magic armor that boosts the wearer's physical capabilities in much of the same way as the Fighting God's Golden Armor. After Rudeus met his future counterpart and was given the future diary, he was given the idea to create the armor so that he could become strong enough to challenge Orsted. He had Zanoba and Cliff work on the armor and was given details about the Fighting God's golden armor by Hitogami to speed up production on the first prototype which was painted in camouflage and extremely bulky, about 3 meters tall and bigger than what the future diary described its version which only covered the body. The next versions of the armor are black and smaller to reduce mana consumption. The armor can also be equipped with multiple tube shaped magic tools that were modified to be able to handle Rudeus' magic power and be able to fire off his standard 『Stone Cannon』 to create a Gatling Gun. The later version can be worn all the time, while the 『Magic Armor Mk I 』 which is more powerful and uses more energy is used for when fighting stronger enemies. The latest version of the armor is the 『Magic Armor Mk II』.

『Summoning Scrolls』
Each scroll has a one time use and can be used to summon the 『Magic Armor Mk I 』.

『Lithograph Stone』
Based off of the seven powers stone created by Technique God, Orsted created a stone that would allow long range communication through writing on the Large Stone. Anything written on the main stone will appear on the sub-stones. Having a main and a sub-stone for the other person's main stone, will allow for long range communication. The stone also requires a bit of magic to actually use so it is not a widespread tool.

The second relic is a blood-stained cloth from when the goddess of love, Sylphy, cured him of his ailment. The third relic is a wooden sword that was placed in the basement shrine to symbolize the goddess of war, Eris, who saved him from death. The religion is called Roxyism, due to Roxy being the main and first goddess. He frequently uses the panties as an object to pray to and to have it give him strength to not cheat on his wives.
