The city of Seoul is known to be a bustling hub where the supernatual intermix with humans. Until someone or something decides to tip the scale and starts mass murdering both humans and supernaturals in the city, trheatening to expose their deep secrets and upend the delicate balance that the supernaturals have been hiding for generations.

Someone doesn't like the intermixing of supernaturals in groups and the pattern doesn't become apparent until after Yeo Hwan Woong is attacked a few days before the annual Blood Moon while out on errands with his group mate Lee Keon Hee. Its up to the BTS group, a mix of vampires and werewolves, to protect the ONEUS group durign the Blood Moon week while they go through finding the culprit behing Hwan Woong's random attack, the motive behind it, and the Blood Moon ritual, all while ONEUS is welcoming 2 humans into their vampiric group only to find out one of them has werwolf blood into their DNA AND having the Vampire and Werewolf Councils breathing down their necks because of it.
