Who on earth walks around dressed like a nun in places you're unlikely to encounter one? It's Japan; people will just assume it's cosplay. The blood and nun outfit together just makes it more authentic (as cosplay).
Unless you're in very specific parts of Japan, people don't just walk around in cosplay.
Also, blood has a very distinct smell. People will notice if you're covered in the real thing.

You see a cute young girl at the mall in Japan wearing a nun outfit covered in blood. You assume:
She's a real nun. Outside the convent. In a country with 0.34% Catholics. And she killed someone. Then, instead of disposing of the evidence, chose to keep the bloody outfit as a trophy and confidently walk around wearing it in public.
You call the police.
She's a weirdo in a cosplay outfit covered in animal blood. She's pranking the person she's meeting up with. Or she's pranking the public.
You silently observe her for your own entertainment.
Maybe you look around for hidden cameras because you're about to become a background character on TV or YouTube.
Maybe record it yourself so you can say "I was there" when it goes viral.
I'm thinking #2 would be the more plausible assumption for most people. Hence, in response to the original question, she hasn't been arrested because it's too bizarre for people to believe it's real.

Those are two separate questions that you've lumped together.
This is not real life Japan. There are vampires. There are official vampire hunters, of which this woman is supposedly one. The proportion of Catholics and other types of nun may be different.
There are non-Catholic nuns.
It's not unheard of for nutjobs to have weird outfits when they do nutjob things.
She could be a fake nun, but the blood is still real, and as I already pointed out, it would be really obvious.
Even if it's some kind of stunt, real blood is a biohazard, so she shouldn't be doing that; the police should be called even if it is a prank. If it is some TV show they got permission to do, police should be there specifically to show people that everything is on the level.
It only takes one person to think it's weird and call the police, even if many people wouldn't.
So the more likely answer to the original question of how she isn't arrested is that she's a law enforcement officer (vampire hunter), who is recognizably in uniform.
