Why does this manga have so many votes for "serial killers" as a category? Did some group of people get together and decide to make a joke out of it? Admittedly, the idea is a bit funny...

Lul I've been wondering the exact same thing 😀 D Trolls, maybe??

Well, some people voted for Yandere, too. Maybe it is because in the manga Sadako is often mistaken for a horror film character.

adds 'apocalypse'

Get revenge - sh!t on a pigeon!

It's also put on other Shoujo mangas. It really is trolling, Funny or not.

Everyone has an Angel. A Guardian who watches over us. We can't know what form they'll take One day, Old man, Next day, Little girl. But don't let appearances fool you, They can be as fierce as any dragon. Yet they're not here to fight our battles. But to whisper from our hearts. Reminding that it's us. Its everyone of us who holds power over the world we create. -Sweet Pea
