Vampire Ninja
I did forget to mention the MC can be very annoying with the way he seems to fumble the majority of situations he's in but if you can accept that early on and it won't frustrate you much I think you'll be fine. I think that is partly the reason a lot of people don't enjoy it as he can make it repetitive at times and from what I've heard of the manga, the story is still quite repetitive.
A relatable main character, I'm in.
