Ikki or Ukyo are the only ones I'd pick between. Kent is okay though.

Shin isn't my type and Toma is a disgusting perverted kidnapping abusive creep.

It is actually pretty frightening to see how many people who would choose Toma after what he did to the Heroine...

I'd pick Toma. Both because he's my favorite character in Amnesia and because his world is the safest one.
But to be honest, I'd be fine with any of them except Ikki. I like him, but because of his crazy, stalking fangirls, I'd never be able to feel safe.

Edit/Added: Toma may be a bit of a yandere, but I'd much rather have an overprotective boyfriend rather than psychotic fangirls after me.
Toma at least wants to keep you safe from danger. Ikki's fangirls are purposely trying to send you to the hospital. Maybe even kill you in order to keep you away from Ikki.

Toma drugged you...and locked you in a cage...that isn't overprotective....that is down right sociopathic. WTF is appealing about that. Liturally nobody should be okay with that. Nobody would wake up after being drugged and locked up and be all "Oh this is fine". Nothing is right about that and there is no way to defend what he did. You'd rather have a boyfriend who ordered you around and wanted to control your every move, then have to deal with a few stupid girls? Frankly Toma is more criminal dangerous then a few girls. People like Toma are the type you see on the news and hear about in murder stories. I mean seriously, just because he is cute people would rather be with a psycho then deal with a few problems. I have had friends who have come from relationships like Toma's. They are not damn pretty or romantic or anyway alright. It is just sick and not a joke. Controlling people and ordering them around is NOT a healthy relation. Drugging and kidnapping them? Even more unhealthy, and down right illegal. How does that sound like some perfect dream guy. WTF is up with this fandom.

And if we are talking about the safest world, that would easily be Kent or Shin's anyway.

In Toma's you must deal with him and Ikki's a few girls. Which the girls you can get to back off, Toma clearly can't take no for an answer.

^ What's the heck is wrong with you? I only gave my own personal opinion of which choice I would make. Who are you to tell me what I can and can't think? It's not your business what MY choice is and you're not allowed to question it either.
People have different opinions. That's something you have to accept and respect without questioning someone else's personal thoughts.

Shin is totally my choice!
But I agree with Ryuuto about opinions. PQ, you can't be that rude only becuase of an opinion. I'm sorry if I seem rude, but she's right. Other people's opinions have nothing to do with you. You may dislike Toma or even hate him if you want, but you can't tell people who like him that they are wrong. And from how I see it, Ryuuto wasn't even talking to you, so why do you spend so much of your time writing a rude comment? And for a made up character who doesn't exist? Don't you think it sounds a bit ridiculous? :/

toma is abusive and disgusting and unless its for coping reasons i see no reason to find redeemable qualities in him (in his relationship timeline at least. i dont remember how he was in the other timelines)
shin?? never stood out for me.
ikky just pisses me off
kento is a sweetie
UKYO THO. WHERE IS UKYO LITERAL SON
