The game starts with the MC going to a place where he enters a conteiner and it's teleported to what i remember is another world, where he meets a vampire girl, after that i think they go to a black market for a slave to protect the MC, also the vampire girl is kinda overpower and the slave girl is in the shadow of the MC. I'm sorry for the grammar in the post i hope somebody can help me to remember the name of the game i'm looking for, either way thank you for reading this post.
