I do not own High school DxD.

This is another OC. This one also has a Sacred Gear I came up with.

Name: Luca Schmiedherz

Race: half-human, half-fallen angle

Age: 18

Physical description: Luca has shoulder length black hair and emerald green eyes. He is 185 cm tall.

Personality: Luca is a calm and analytical person. Will he is not emotionless he rarely says how he feels. He shows it through facial expressions. Luca also shows his closeness through physical contact more then words. The more comfortable and trustful he is toward someone the more hugs he gives and the longer he cuddles with said person. Azazel has many pictures where Luca hugs Vali, Baraqiel or himself.

Country of origin: Germany

Relatives: Parents (deceased), Azazel (caretaker), Vali Lucifer ("brother"), Baraquil ("uncle")

Occupation: student of Kuoh Academy (later), parttime agent of the Grigori

Abilities:

Holy Lightning: Luca inherited this ability from his father. While his lightning is not as strong as the lightning of most fallen angel he makes it up with the way he use it. Baraqiel also taught him how to use them when he was younger. He often boosts the strength of his holy lightning by simultaneous using lightning magic and also often use his sacred gear as a conduit for his lightning.

Magic: Luca learned many magic styles. His strength lays with lightning and sealing magic. In addition he can also use fire, wind, light, healing, defensive, strengthening, security system, teleportation, runes symbol, summoning and fallen angel magic.

Close quarter combat knowledge: Growing up with Vali Luca had no choice but to learn hand to hand combat. He also learned how to use and fight against weapons. More to know how to defeat a weapon-user then to know how to use a weapon (except his chains).

Bondage technique: Luca is not into it but Azazel taught him it as a joke. Luca however was to young to understand and thought that it was just binding technique and learned it. In one of his mission years later somebody told him the truth. It embarrassed him immensely and made him the laughing stock for a time. Vali and Azazel especially like to bring it to embarrass Luca. Luca still uses it since it is surprisingly effective to keep captured opponents in line.

Flight: He has four fallen angel wings.

Equipment:

Great Chain of Being: This sacred gears is one of the last sacred gears God created. It is a concept given form. The material used for it was a part of God himself. It can create chain with varieties of abilities or forms such like sealing abilities away, moving around without the users or kusarigama. The strongest chain can bind everything. Only beings which are far stronger then God could break out of them. Despite the potential Great Chain of Being is not considered as a Longinus since only a few user had awaken its full potential (Luca is one of them) and that it miss the power to kill a god.

Relations:

Azazel: Luca likes and respects Azazel even if he wouldn´t say it to ensure that Azazel's ego does not grow even more. While he may make it seem like he is annoyed at the missions he does for the Grigori he is secretly happy to be able to repay Azazel a bit back for taking him in. Azazel will never be Luca´s father but he is still apart of Luca´s family.

Vali Lucifer: While both would deny it they are brothers in all but blood. When they were younger Vali would get them often in trouble and Luca would try to get them out of it (which more often then not failed). Vali also unknowingly helped Luca after lost his parent by telling to be strong enough to protect those who are close to him the next time something happens. Vali considered to make Luca the first member of his peerage but decided against it since Luca did not wish to limit his involvement with the mystical world (less trouble in Luca´s mind).

Baraqiel: Baraqiel was one of the people who knew about Luca even before Azazel took him in since Luca´s father and he were good friends. He taught Luca both because of his late friend as well as Luca´s situation reminds him of the situation of his daughter. They get along great and are often seen as uncle nephew (which they technical are).

Backstory: Luca´s story begins with his parents. His father was an angel who fought alongside and fell with Baraqiel. They were great friends and hold each other's respect. He made personal enemies with some minor devil clans over the time of the great war. When Luca´s father met his mother he left the Grigori. Luca´s mother was a magician from a long line of magicians. Her family had some dealings with devils which attracted the attention of a group of stray exorcists. When they attacked only Luca´s mother escaped everyone else died. She laid low for a few years until she met Luca´s father and was warped up in a mission of him. They fell in love and two years later Luca was born. When Luca was 6 the old enemies of his parent caught up to them and attacked them. In this accidental combined attack both of Luca´s parents died but not before calling for help from Baraqiel. When he arrived he was met the stray exorcist and devil fighting each other. Baraqiel was so enraged that he killed all of them. As he looked around he found Luca alive and unharmed.

Since Baraqiel had no idea how to raise a child he asked Azazel to be his caretaker since he already had Vali. Azazel accepted and took Luca under his wings. After awakening his sacred gear he wished to be trained. As Luca grew up he did task and smaller mission for Azazel. His latest mission was the investigation of a group of fallen angels who could not be reached. This brought him to Kuoh City.

So what do you think? I wish you guys a good day.

Goodbye with my best regards.
