Sigurd

Sigurd was formerly an aged man who had died old in a hospital, who was able to reincarnate into the same world that has some differences, which he knew as High School DxD. He was born in a test tube in the Sigurd Institution, and, due to him being the second-best among the test subjects, he was given the name of Sigurd.

He is the main protagonist in the fanfiction DxD: Black Ice, Fallen Church which is currently just an idea in the makes.

Appearance
Sigurd has generally messy white hair with the bangs falling down to his eyes and partly over his ears, which he calls the "main character look" and dark red eyes, much like the other members of the Sigurd Institution. With healthy pale skin, he has a rather scrawny build, yet he is still quite powerful due to the years of exercise and training he has been through. Sigurd has a slightly-below average height of around five feet and four inches.

His casual wears include wearing two black rings on his left hand, around his middle and ring finger, a long-sleeved black shirt and dark blue jeans with black shoes with white on the sides. The shirt is pulled down on the right side past the light blue belt and is pulled up on the left, revealing the belt. He generally has an untidy appearance when he is casually dressed.

When he attends Kuoh Academy due to wishing to mess with the plot, he wears the standard male student uniform, though with a few changes. While he does wear the black blazer with white lining, an open white dress shirt, and black dress pants, he has on a light blue shirt underneath the dress shirt and his regular black shoes with white on the sides, plus his two rings on his left hand. He also dyes his hair with washable dye for blond hair and puts purple colored contacts in his eyes.

When he is, as he puts it, doing "Grigori shit", he wears a different outfit without his contacts and after washing his hair to make sure no dye is left in it. However, he keeps the rings on (which is a stupid thing to do in hindsight, but he figures that plot will keep him hidden from people who know his other identity).

He wears a black jacket with a hood, that he always has on, over a black shirt and a black face mask with some white on the sides. He also has on black pants and black combat boots. Truly, he is going for the "dark edgelord" look.

Personality
Sigurd has two personalities that he switches between, which is his original personality and his created one for when he is "Black Ice".

Before and after his reincarnation, Sigurd is a nice and kind man who is always energetic and outgoing; going out of his way to help others when they need it, even if they don't ask. Though not always smiling, Sigurd always keeps a positive outlook on things and is described as being optimistic to a fault, as he thinks something good will happen if one just believes that it will, even in the most horrible of circumstances. However, he can be rather rude to those he dislikes and will usually glare at them, which is also a small tick he can't stop, no matter how hard he tries. When he is near someone he hates, he gets more aggressive and violent towards them, until things deteriorate into a fight - it happened plenty of times in his school days in his previous life.

When Sigurd assumes his "Black Ice" persona, he always dons a more serious look, which he refers to as his "batman form". In his batman form, he is usually cold and dismissive. He speaks in a more formal tone to others, usually affixing them with honorifics, such as "lord" or "sir". Sigurd always tries to appear to be quite calculating in this form to give him an air of mystery, that all main characters must possess, as he says.

History
Sigurd used to be an old man in a different life, one where the world he currently resides in was but a mere story written by someone that Sigurd proclaims as the "ultimate pervert". In his later years, his grandkids got him into watching a known anime called "Fairy Tail". Sigurd was enamored by it. Since he usually didn't do anything at home, besides eating, sleeping, and talking to his family or friends when they called and hardly leaving home except to buy groceries, he watched anime to pass the time. From that first anime to others, such as Fullmetal Alchemist: Brotherhood, Bleach, and even Gakkou Gurashi, he eventually watched one anime whose main character reminded him a lot of his younger days, when he was in school.

Now, a lot of characters did sport a resemblance to his younger self, but, for some reason, he felt more attuned to the main character of this anime - Hyoudou Issei from the infamous High School DxD.

Like the young pervert, he also wanted girls to love him in his high school days, though unlike the young pervert, he actually got girls - who he also cheated on with other girls. He wanted a "harem" but he ended up hurting the feelings of the girls he picked up. When he went to college, his future (now deceased) wife got him straight. She taught him that he should only be with the girl he "truly" loves - which ended up being her.

Years later, and they had their own kids and they had their own kids. Eventually, she passed away, leaving the old man alone in his house, with his children and his grandchildren visiting sometimes. Eventually, his grandkids would introduce him to anime and he would fall in love with it...

When he later passed away in the hospital in the middle of the night, he ended up facing a "deity" of sorts, who, after having a nice ol' chat with the old man, reincarnated him into High School DxD as an artificial human in the Sigurd Institution. From then on, he made it his goal to change the plot as much as he wanted, but first - he had to survive and make it TO the plot. Achieving this, he wants to make his own harem filled with women he can say he loves as much as his first wife. He believes this will be a difficult goal, but in reminiscence of his former high school days, he will achieve this. As he has already decided to do so; he will.

Powers and Abilities
Enhanced Strength - Due to his rigorous training in the Sigurd Institution, he can match various Stray Devils he fought in his service to the Church, able to fight back against them and even push them away. He has a similar level of strength to a Low-class to Mid-class Rook.

Enhanced Speed - Due to his rigorous training in the Sigurd Institution, he can move faster than bullets even when fired three centimeters from his head, he can still dodge the attack. His speed seems to be between the range of a Low-class to Mid-class Knight.

Enhanced Durability - Though his body is artificial, it is just as strong as a normal human. Even so, due to his rigorous training in the Sigurd Institution, he can endure a higher level of pain than normal humans and even move his body in a way as to minimalize damage to it that he can't dodge.

Enhanced Stamina - Due to his rigorous training in the Sigurd Institution, he can fight or move his body for long periods of time without tire.

Expert Swordsman - Due to the training he had been put through by the Sigurd Institution in training on how to wield a blade, he became a proficient swordmaster. He can match Siegfried in swordplay quite easily, though he'll lose in the end due to Siegfried possessing a Sacred Gear.

Lackluster Magician - Sigurd, when in the Church, studied multiple forms of magic theory and formulations, though his talent is lackluster in utilizing magic, due to him having to use math, as he is just a human. Because of this, Sigurd does want to reincarnate into a Devil, but doesn't want to be someone's "pawn".

Average Magic Power - Because of his lackluster ability as a Magician, he doesn't have much power to utilize due to his low training and skill. However, he does possess an affinity for ice-magic.

Dáinsleif
Alternatively known as the "Demonic Crystal Sword" or as the "Dark Frozen Sword", Dáinsleif is a Demon Sword from the Norse legend collection in the Tyrfing Cycle. It possesses the ability to create and manipulate ice, specifically, black ice, which is where Sigurd gets his name from, though it usually makes light blue ice that does not reflect anything. Dáinsleif is a long sword with a pale, almost see-through, white and blue blade, that has gold lining near the hilt. The crossguard is in reminiscence of bones, specifically, the pelvis, with four pieces of ice stretching out from the sides, like a claw or a dagger, two on the left and two on the right. The crossguard has a red jewel in the middle. The handle is mostly gold with the middle portion being silver, and the pommel ends in a round point.

Trivia

 * Sigurd's physical appearance is based on Zakuro Oshigiri from "The Ones Within".
 * His sword, Dáinsleif, draws its appearance from "Fire Emblem: Sacred Stones", from the sword Sieglinde.
 * His alias, "Sjur Vols", comes from two sources, both of which are related to the name of Sigurd: Sjur is the shortened form which means "victory" and Vols is short for the Volsunga Saga that Sigurd comes from.
 * Hiro is because the pronunciation is similar to the word "hero", which Sigurd is - a hero.
 * Him trying to become a Magician is because he wants to use magic like the nerd he became.
