Seki

Seki is one of the main characters of War of Existence, the Human Variant designed to investigate the Saint

 Elite, Azul 's master and protector, and, after the Battle of the Saint Elite Tower, an official member of the Divine Entity.

Origin and background
Seki was once a normal human soldier, struggling for survival in the last human army, the Saint Elite killed him because he discovered critical military secrets in a human laboratory.

Under the condition of investigating a possible betrayal, the Divine Entity gives him a new life and powers superior to an average Elite member, to ensure their goal, they removed most of his human emotions to prevent him to feel any sympathy or compassion for human life, given humanity was being judged, to ensure his obedience and reilability in combat.

In War of Existence, Seki is a very strong and cold hearted warrior, he becomes Azul’s Master and with Sabrina’s help, starts acting like a human being again.

Personality
Before his death, Seki was a caring and righteous man, his personality managed to gain the friendship of a very anti-social Samanta, also member of his squad in the last human army.

After his death, when he was turned into a Human Variant, most of his human emotions were removed, turning him into a cold hearted warrior, only focused on his duty. This change and his physical appearance, resambling a Saint 

Elite member, made Samanta act cold with him. A few factors affected his personality since then, Erste 's reality manipualtion over his dead body made him save some momories post death. Azul's appearance made him think of the girl Samanta wanted to save, Raid, he trained and protected her in hopes to find out more about it. Later, Sabrina would be the only one understanding the paradoxical feeling of emptiness his lack of emotions caused him as these started to slowly return, forming Seki's Impossible Dilemma.

Physical appearance
Seki is a tall man, with black hair and eyes, and in War of Existence he can be seen with an uniform similar to those used by the Saint Elite.

Abilities
Seki is by far, the most powerful individual in War of Existence, and the biggest threat to Erste's plans, this is because the Divine Entity gave him abilities capable of overpowering all the members of Division Six.

Martial Arts Master:

Seki is expert in hand to hand and sword combat, he had extensive training in life as part of his duty in the army, the Divine Entity also enhaced his reflexes, physical strenght and speed.

Sanni:

Sanni(निराशता sanskrit lit. "despair")Seki's signature attack, an invisible, unblockable and extremely fast energy wave that attacks its target soul, tricking it into believing it's host is dead, leaving seconds to a few minutes before the target's unavoidable death.

Because of the nature of this skill, being very unfair and almost impossible to figure out before it's too late, most encounters end in a one hit kill.

Seki also shows himself capable of bending this energy into a masive barrier, and using it without his sword.
