Fenrir

Fenrir (フェンリル) was a member of Cult of Diablos, being the 5th seat in the Knights of the Round. He was killed by Shadow after the latter investigated student disappearances at the Midgar Royal Spellsword Academy.

Appearance
Fenrir usually takes and maintains the appearance of a young boy with silvery white hair, who is still strong for an ordinary individual to engage with.

However, Fenrir could change his appearance like the fabled Midgar Devil in the past by becoming a frail elderly man, with his hair turning white as his face was covered in deep wrinkles, and his limbs became emaciated, when he wanted to get serious or when he met a more dangerous enemy like Aurora or Shadow.

Despite his appearance, Fenrir's strength had increased so much that opponents against him were breaking out in cold sweats from the intense pressure of his strength and the weight of his oppressive aura.

Personality
Fenrir was a former assassin who took pride in being a murderer, claiming to have killed countless people to reach the "pinnacle of martial prowess". Overall, like many of the cult's higher-ranking members, Fenrir was a delusional psychopath completely convinced of his own invincibility.

Fenrir loved fighting strong opponents, as he got excited at the prospect of fighting Zeta and Shadow after hearing of their prowess. He loved the thrill of fighting Aurora when she possessed Claire's body, and was finally ecstatic when "Suzuki" fought him before revealing himself as Shadow.

Fenrir, aside from his rivalry with Loki and his faction, scoffed at the weaker members of the Rounds, having never acknowledged the likes of Petos and Nelson taking seats.

Despite living for hundreds even thousands of years, Fenrir can never achieve what he called the "peak of martial prowess" after religiously training for as long. Thus he had simply given up his dreams and settled for the next best thing, experiencing this peak from someone who can best him and gladly perishes before the might of Shadow. Unfortunately for him, Shadow gave him an unexpected response that completely shattered his worldview and reignited his passion just moments before passing away.

Background
Fenrir was once known as the strongest magic swordsman who lived centuries ago, as he made a name for himself around the world using his weapon, "Blood Fang", the sacred sword of the once strongest swordsman.

He is also a greedy assassin, who only wanted to increase his own power by indiscriminate slaughter, which made him a feared assassin in the Midgar Kingdom, known as the "Devil of Midgar," or the "Midgar Devil," to which everyone who lived in the kingdom knew and even feared his moniker.

At some point, Fenrir joined the Cult of Diablos and became the 5th seat in the Knights of Rounds, as he and his faction controlled the Midgar Kingdom's criminal underworld for so long, as he annually consumed one of the "Tears of Diablos" to maintain his strength and immortality. Fenrir and his faction had been engaged in a fued with Loki's faction for a long time.

Cult's First Unusual Report
About five years earlier, there was a report of an attack on their demon possessed carriage by an unknown group. Fenrir wanted to handle the issue because of his suspicions on the report, wanting to ensure there wouldn't be eventual problems, but the other Rounds postulated that a monster attacked the carriage, so they let it go.

Unbeknownst to them, it was bandits who attacked the carriage until they too were decimated by Shadow, who then found the a possessed figure who became known as Alpha, and the two would co-found Shadow Garden soon after.

Decline of Fenrir's Sect Faction
Fenrir heard several reports about carriage attacks, their branch headquarters being destroyed, and several of their members being killed, including members of the Rounds. Fenrir even noticed the repeated operation failures, including Grease's death and the failure of securing Claire Kagenō. Because of the suspicious activity in Midgar Kingdom, his territory was systematically targeted by an as yet unknown group that made his faction fall into decline for the last five years.

It was then Fenrir noticed Shadow Garden was the group responsible for destroying his operation after Zenon Griffey's failure attempt at securing Princess Alexia Midgar. After the release of Diablos' left arm during the destruction of the Sanctuary at Lindwurm, and failure operation of retrieve Rose Oriana during Bushin Festival, Fenrir went to the meeting with his fellow Rounds to have them act seriously about crushing Shadow Garden.

After the meeting, Fenrir decided to revive the Diablos' right arm at the Midgar Academy to resupply Tears of Diablos. But, upon learning that the Great Commerce Alliance had collapsed due to John Smith and Yukime's actions during their secret commercial trade war with Mitsugoshi Company by seizing all Alliance assets and Cult funds, his faction received substantial financial damage, scraping funding only to afford sending Second and Third children to support Fenrir's Sect. Because of this, Fenrir and his faction could only seek cooperation from other factions because the threat of the Shadow Garden and his Sect was already devastated economically.

Aurora
When Fenrir heard the name Aurora from Claire and he wanted to confirm it by fighting.
