YES.

But this of course is my opinion.

In regards to your comment funnyjunk.com/user/blackcomet/215#215.

If you were angry it was probably your adrenaline; warmer blood to heat up, expand, and loosen your muscles; along with your larynx's position. If you contract your Larynx/throat you get a higher pitch, and if you expand it you get a lower pitch. You can feel the difference if you put your hand on your throat. Your Laryngeal Prominence, Adam's Apple, will go up when you contract your Larynx, and down when you expand it. The further you expand the deeper your voice gets. However it is harder to speak if you are not accustomed to speaking in the expanded state. I suggest practice.

Hnng-AHH!

*sigh*...I'm sorry Master, what did you say?

So, did you stick inside your sister after you pinned her?

I would say yes, but that is my ****** talking.
If you can deal with the phone calls in the middle of the day and their constant defamation, then I would say yes. All one would need is to act a bit obsessively. When you spend time with them say things affirm their obsession, low self esteem; whatever their "yandre" may be, and you'll have a decent relationship.

Can't have female friends though

You can, but she'll be jealous and think you are cheating on her. If she is "crazy" about you then you wont have to fear for your safety. If you come home one night and she is waiting in a dark room and asks you where you have been, all you have to do is be honest. Because she was probably watching you anyways; you can talk her down so long as you are calm and don't lie about anything physical. Things like "You are the only one for me.", "There's nothing to worry about.", or "I'm not going to leave you." are all words with no physical proof, and can calm her ********** if need be. However things like "I wasn't with (Name) today.", "I didn't kiss her.", or "I'm not doing anything behind your back." are all things that can be proven or disproven through stalking. Avoid open areas when you choose to cheat on "Yandre", and you'll be fine. In my opinion you wouldn't need to cheat on a yandre because you could go all out on your ****** and they'll be with you. If they don't want to follow anything you tell them to do just ask "Why not don't you love me?"; you'll have to alter this sentence if you keep on encountering this problem but keep it to the same effect. Hug her a lot, over 20 seconds, to calm her down if she is upset, and give her affirmations to your "love".

What about the safety of others?

I can think of something to do to 'affirm' our love

sorry for the late reply. Was on TF2

and then, the giant african knife gets involved

That actually that's a Kukri, it's a south Asian, I think Nepalese, weapon and tool.

If she comes at you with a non-projectile weapon, just grab the hand it is in and push her wrist down, towards the bottom of her forearm, and her grip will loosen. At this point grab the weapon out of her hand and through it far away. Then turn her back to your chest and put her in a bear hug like hold, but hold her wrists to her chest. Wait till she calms down and talk to her. Say what you can to set her at ease and make her vulnerable emotionally. At this point you should have her by her emotions. Sex is the only option to close the subject and quell any ********** or doubts for the time being.

Huh...well I don't know what to tell you then.

You could just do to her what I am planning on doing to Scoonus.

You called master?

Yes.
Pick up that stick and slowly... and carefully now... AGITATE THE HELL OUT OF THIS SNAKE!

*prod*
*prodprod*

...sir I don't think- WAAHH!!!
>gets attacked by snake

Yess, this pleases me....

OH GOD!!!

MASTER! DO SOMETH-AAHHHH!!!!!

Fine, but this is the last time. Now don't move, I need that snake alive.

...M-Master?

What are you doing with that?

Ah, I'm not going to kill just yet. I still need something to satisfy my sexual desires.

>Whistling noises
>Revs chainsaw
>Still whistling
>Stands over Scoonus

MASTER!! WHAT ARE YOU DO-AAHHH!!!
>still being attacked by snake

Not S enough for that

Just make sure you are the dominant one in the relationship. Otherwise it could be...unpleasant.

Unless... I'm actually an M

Do you like being sodomised and/or cut up? Or being masochistic outside of the bedroom causing your life to be restricted, she has control over your finances, you can't go any where with out her consent, no social life, and constant phone calls asking where you are?

Not my thing, but others' may like it. I imagine it will be worse with a yandre.

I'll make sure there are rules
>I have money
>I go out
>I'm social
last one actually gives me a reason to use my phone

If anything, she'll be loyal unless I get involved with a girl in any way

"If anything, she'll be loyal unless I get involved with a girl in any way[.]"

It depends on her yandre, her obsession, need, or void. There are many types of yandre, the one in the manga snips you posted is a dominator. Yandre rarely has an equal ground with their partner. If you want ground rules you'll have to be the dominant one, even if it is by a just a little.

I can if I have to. My sister learned that the hard way. I never knew my voice could get so deep

Well going Barry White on a woman works too I guess.
My first thought is somewhere around violence, demoralization, and intimidation. But I almost always restrain myself and end up talking it out.

If your way works go with it. Every situation is different and all I can give as advice is theorized situational examples; step by step solutions to solve them; and the reason and desired outcome of the given solutions, so that you can adapt to alternative but similar situations that may arise.
