“The Black Wings have left their mark on my body, and I am able to raise their followers. From now on, crows will always be by my side. Their strength grows day by day, and I will rise higher and higher with them.” -

Wait, this isn't Daying?

magic? What kind of unscientific stuff is this? Vampire, werewolf? What kind of fantasy stuff is this?

Forget it, does this prevent me from opening a detective agency?

The beautiful British-style detective is here! Get out of the way!
