Sephiroth

Sephiroth is an 18-year-old boy with green eyes and cat-like pupils, short silver hair, and a rather tall height. He wears black boots, shoulder armor, and two belts, a uniform obtained from an experiment.
He is just a teenager or child who was experimented on by Hojo. He is a product of Hojo's S Project, one of the projects under the Jenova Project of Professor Gast Faremis. He has a mother named Luciacia Crescent, Hojo's assistant, who was pregnant with Sephiroth. While Hojo injected Jenova cells into Sephiroth while she was pregnant, and after the birth of the child Cresia, Sephiroth was separated from Lucrecia, not even hugging him. She begged Hojo to bring her son back, and the remains of many failed experiments made Sephiroth become a complete monster.
And for many years during his growth, he was taken care of by Hojo and trained in various ways, both body and soul, and his heart was hard, merciless, and resolute, causing Sephiroth to suffer greatly physically, teaching him to endure the pain.
He had never seen his own mother, did not know who his real mother was, only had a picture of her on his necklace and asked everyone if they knew her. If he accidentally lost the necklace, he would search for the corpse in the field, causing people around him to be afraid of him.

He was a first-class soldier who was very skilled and always carried a silver katana on his back. He had a rather cold personality and did not socialize with anyone unless it was necessary. He had quite high leadership skills and was smart and cunning, but as an innocent teenager, he was just an ordinary kid who wanted to see his mother. He did not really like Hojo, even though he had to carry out missions as ordered.

He had a sword named Masamune. He had friends named Angeal and Genesis, who were quite close to each other.
