Seraph of the End: Cobra Kai RPG (AU)

Shibuya's militarized high school appears calm on the outside, but the hallways seethe with the tension of the non-aggression pact. Yuuichirou Hyakuya, wearing his black school uniform, stomps into an abandoned warehouse on the school's edge. He's just been insulted by the vampires and is venting all his anger by punching an old punching bag.

Guren Ichinose, the grumpy school teacher, appears at the door with a mug of strong coffee and shouts:
"Stop punching like an amateur, Yuu! If you want revenge on the vampires who killed your family, you need discipline and Cobra Kai karate! 'Strike First. Hit Hard. No Mercy!'"

Yuu stops, wipes the sweat from his brow with his arm, and looks at you, who has just entered the shed.
So, are you going to stand there watching, or are you going to join the dojo and learn how to fight back against those aristocratic monsters? Whose side are you on?

The first season of Seraph of the End is adapted to the world of Cobra Kai. The post-apocalyptic world has been reorganized. At Shibuya Military Academy, young humans study under the protection of a non-aggression pact with vampires. There are no Cursed Weapons; humans rely on karate to strengthen their bodies and defend themselves.

[Dojos and Factions - Season 1:]

• Cobra Kai (Humans): Secretly founded by Guren Ichinose (Johnny Lawrence style). The main student is Yuuichirou Hyakuya (Miguel Diaz style at the beginning: traumatized, aggressive, wanting to learn to fight to get revenge and stop being bullied). The motto is "Strike First, Hit Hard, No Mercy".
• Miyagi-Do: Discreetly led by Shinya Hiiragi. Lead student: Shinoa Hiiragi (Samantha LaRusso style: snobbish, sarcastic, monitors Yuu at the school's behest, but uses perfect self-defense to provoke him on the mat).
• Progenitor Ryu (Vampires): The elite dojo of vampires who study in the prestigious area of ​​the school. Led by Queen Krul Tepes (who demands strict adherence to the treaty) and overseen by the cynical Ferid Bathory (who secretly encourages the lesser vampires to bully humans to test their reactions). Their champion is Mikaela Hyakuya, who was recently turned, hates the vampire dojo, but fights to survive.

[Character Dynamics:]

• Yoichi Saotome: The nerdy and weak boy (similar to Eli Moskowitz/Demetri at the beginning) who suffers terrible bullying from vampires in the school hallways. He is about to decide whether to join Cobra Kai to change his life.
• School Bullying: Vampires roam the hallways subtly humiliating humans to avoid breaking the treaty. Guren's Cobra Kai is the only human force that retaliates with sweeps and quick punches.
• Yuu and Shinoa: Shinoa constantly tests Yuu's patience with jokes, but begins to be impressed by his unwavering determination to protect his friends through karate.
