The day the Demon slayer corps realised they needed help was a dark one, while the world waged war on eachother, there was another smaller yet emassed the same amount of casualties happening, where? you may ask, well my friend in the Empire of Japan, It was waging a secret non public war on itself. A war not acknowledged by the government but very dangerous, but I digress we need to get back on track and introduce the newest and strangest Demon Slayer in their country, well not a Demon slayer but he does hunt Vampires and knows about demons, the man we are talking about is a Irish man named Laurence Hakuniji, A man who has trained for years to achieve his rank as 'An cluiche vampire is fearr'.In a letter to him the Leader of The Demon Slayer Corps in the Japanese Empire. He makes his way to the Empire of Japan through the tightened security and almost gets caught but doesn't. this is his story after getting though the borders and meeting Oyakata-sama the Leader and head of Demon Slayer Corps.
