is re: zero just bloodborne in disguise: a study by kongo
first off black stomach cutter bad lady's weapon looks suspiciously like the blade of mercy
for comparison:

her weapon

blade of mercy non seperated, when "transformed" it separates into two near-identical looking blades
but of course this could slide as a coincidence because it's just a curved sword, BUT WAIT


WHAT DIS?? IT 2
them the blades of mercy son
this could still be just coincidences though, obviously, but it's just
too similar for me
until we see reinhard

he picks up an ordinary looking sword, which kind of looks like the holy moonlight blade w/o being holy, sans the bandage things

more or less just an ordinary sword
BUT THEN WHAT DIS??
THE DAMN THING STARTS GLOWING
BUT WAIT THERE'S MORE
HE CHARGES UP A GIGANTIC DOWNWARD SLASHAND DOES THE SAME EXACT ATTACK LUDWIG DOESFOR COMPARISON:
reinhard's slashludwig's slashnow downward slashes aren't new
but
glowing sword downward slashes into a gigantic beam of light and destruction is a little too similar to me
not to mention other details such as reinhard saying he "specializes in hunting monsters", and his blade in it's sheath looking suspiciously like ludwig's holy blade
in conclusion: re: zero is actually bloodborne anime, tv tokyo is a secret from software branch
