Karneval (TV)

When watching Karneval, I got the Inuyasha vibe from it. With Inuyasha and Nai being half human, and Gareki's past is similar to Kikyo's past. They both have to do with demons (although in Karneval, they are called Varuga). All in all, they are somewhat similar, and you will get the Inuyasha vibe from Karneval.
