Why are Japanese versions of vampires always obsessed with ketchup, do the people of Japan really believe that red tomato is the same as blood, is this why hentai characters drink so much milk, they think it's the same as jizz?
It's to make the vampires seem less inhumanly appalling, make them more cutesy and relatable rather than a vicious undying monster that rapes your veins for fun and satiety while treating you like garbage cattle.
@Kayriel
It also allows for later fake-drama cliffhanger bullshit when she somehow gets "hurt" only to find out all that blood is fucking ketchup because she keeps a bottle on her person AT ALL TIME.
@Hell_Satan i don't know what you're referring to, most western vampire stories have them drinking wine, like the elitist snobs they tend to be, or treating blood bank blood as if it were wine.
@Hell_Satan Adventure Time (guessing that's the source of HDMI1's image) and children's book Bunnicula, I read that one, it was all vegetables, and the third example given is Rosario to Vampire, which is still Japanese.
