## Biography

### Background

Koeru was the son of Uesugi Hideo, the Yamata no Orochi's stallion. Hideo had a main purpose to his family: to conceive as many children as possible in the hopes of obtaining a super hybrid, also known as a *Shadow Emperor*. These efforts were overall fruitless and most of the babies were fully draconized in the womb.

Hideo's unborn brother became unstable during the gestation period, which killed his mother. Thanks to this, Hideo was resentful of his bloodline. He met a nun named Charlotte Chen, who was doing missionary work in Japan, Charlotte was of French and Chinese descent, they played chess regularly and they fell in love. Charlotte became pregnant and the pair ran away to France and lived there for a time until they were found by ninjas of the Orochi families.

Hideo made a deal, to spare the life of his unborn son and wife in exchange for his return to Japan and the families accepted. Koeru grew up in an orphanage at the Catholic church, where Charlotte became a nun. They had to hide their kinship, but she worked on the orphanage to be close to him. Koeru would also spend some time in the temple to be able to see her.

### Becoming the emperor

After his father died, envoys of the Orochi families were sent for him since it was discovered that he was a Shadow Emperor when his dragon skills awakened and got out of control. Koeru accepted to visit Japan for a few years, expecting to return to France, but he stayed for the rest of his life. As the head of the family, he enjoyed great luxuries and was asked to conceive children with multiple women. He grew accustomed to this life and remained a symbolic figurehead during most of the second World War. During this time, the Japanese joined the Germans and the Uesugi clan sent samples of Koeru's blood to the Nazi scientific divisions in the hopes of learning more about their heritage and using that knowledge to create a strong hybrid army.

After Japan lost the war and the U.S. occupation forces arrived, Koeru had to defend the declining families from Hilbert Ron Anjou, a leader of the Secret Party, but he was inexperienced in combat, despite his superior dragon blood, Koeru lost the fight and decided to abdicate. Anjou asked him if he knew what the Japanese had done overseas, but Koeru was ignorant about the war itself and he started reading the testimonies. There he learned of the Nanking massacre, Charlotte disguised a group of women as nuns to help them escape, but they were all discovered and killed by the Japanese army. Charlotte took her own life after witnessing the horrors committed to the victims.

Koeru attempted to kill the officer in charge in retaliation, since the man used Charlotte's body to test his new sword, but the officer had already killed himself after Japan's surrender to the allied forces. Before he left, Koeru ransacked the family's sword museum and stole many ancient blades. The Orochi families joined the Secret Party and went through a steep decline.

Decades later, Jung Von Herzog used Koeru's genes in countless experiments, including the creation of three hybrid children: Gen Chisei, Gen Chime and Uesugi Erii

### Retirement

In the following years he became a devoted preacher at a catholic church. He also trained to become a ramen master and opened a stall. He had a degenerative disease that would have killed him if it wasn't for his healing abilities.

### Return

By 2011, the Yamata no Orochi had recovered its former glory under the leadership of Masamune tachibana and decided to break away from the Secret Party. Anjou arrived once more at Japan and visited Koeru's ramen stall, much to his chagrin. Koeru narrated his life story to Anjou, as well as the principles of the Shadow Emperor and the connection of the Japanese hybrid bloodline to the White Queen Izanami.

### Last stand

During the resurrection of the White Queen, Japan was hit by a tsunami and a mass evacuation begun. Koeru decided that he wanted to visit the church where his mother lived one last time and ran towards Anjou. On his way, he crossed paths with Gen Chisei on the street, completely unaware of their kinship.

He reached Anjou and begged him to let him escape the country so he could visit France. Anjou scolded him, but in the end pitied him enough to give him access to his private jet. Before Koeru left for the airport, Anjou revealed to him that he had children, and for the first time in a long time, Koeru didn't feel alone in the world anymore. At the airport, he witnessed the security personnel forcing a small child to give up her pet cat to board the plane, he gave her and her family access to Anjou's plane so they could escape and then returned to the city.

Koeru met Anjou, Chu Zihang and Caesar Gattuso while they fought against a resurrected dragon corpse, Koeru used the Black Sun Yanling to attract the swarm of servitors and burn them in a fraction of a second; He slayed the beast and saved Anjou, and he asked him many questions about his sons, how were they and what their personalities were like. The pair was overwhelmed again and both of them were exhausted, but a sulfur bomb brought by the college to kill the servitors was about to explode.

Koeru warned Anjou about the possibility of an unknown enemy, he assumed that someone was awakening the dragons and using Cassell and the Secret Party as chess pieces.

Koeru threw Anjou away from him, he started the ultimate Black Sun while the principal and his students escaped in a helicopter. Uesugi's skill created a vortex in the middle of the ocean and it pulled a swarm of Ghost-toothed Dragon Vipers towards him. Anjou ordered the helicopter pilot to wait for Koeru, but the old man was not intending to leave with them. Uesugi's last words were said with a smile, "Farewell Anjou, you damn devil!". The sulfur bomb exploded, killing Koeru, the servitors and the swarm of vipers.
