Can I kill my yandere and end everything?
You can, but it's not easy.

From 65% easy to a solid 0%, you can kill your yandere.
The only way to kill a yandere, is to try something that a dumbass didn't do.......
.....Akise Aru......You know your mistake retard.

Never anger a yandere, it decreases your chances of being able to kill her/him, and they can turn the tables.
That's my only best advice.

You kill your yandere, you're sending yourself to hell
Killing love isn't a good thing.

So you kill your yandere, they can have your neck hanged, while they're holding the rope, and you're being dangled over hell, while they're possibly in heaven, or if they're in hell too.....Then you're stuck with them, even in death.
Yanderes are like curses, you're stuck with them

BUT, getting your yandere to fall for someone else?
That's kinda hard, but it can work.

1. The kinda person you are, find someone that's like that, or better.

2. Talk about him/her to your yandere, and see if they have more stuff in common

3. To advance it even further, your yandere and your 'replacement', can have a romantic moment.

If that fails, then sorry, but that's all I got.

However, the lower your yandere's level, the more easy.

If your yandere can leave you for anyone, then your yandere is actually just a crazy b*tch, or dick.

That's all for now, have any ideas for getting a yandere off your back, and no blood shed happening?
