Highlander

London, England, is bustling with strange beings that seem like they only exist in imagination, such as vampires and werewolves. Di Dunwell, a secret organization agent from the intelligence bureau and a Highlander, is injured in a battle with an unknown enemy and loses consciousness while fleeing to a safe house.

In the middle of the night, he crashes through a roof and falls into a family home. The next morning, Di wakes up to find himself face to face with Jack Ironhide, the terrifying house owner with dreadlocks and sunglasses, a two-meter-tall giant.

He then learns that this simple-minded-looking man is actually one of only two blacksmith masters in the world, and the smith who forged his dagger, "Khalil," with which he has fought for a long time... As Di, as an organization member, tracks down a series of murders committed by an unidentified otherworldly creature and gradually lowers the walls around his heart while bickering with the noisy Jack, a modern fantasy combat romance unfolds between the blacksmith of Muspelheim, who creates the world’s strongest weapons, and the immortal Highlander.
