Looks like the incarnate system in AW. Oh wait.

I think Kirito can just couple or marry Sugu in the mmo world while marry Asuna in real life. Can get both what? Besides, even I did saw my friends marrying each other in Ragnarok Online just for the sake of enjoying the benefits (sharing item, exp. etc) eventhough both of them are guy.

when they died, some penalty will be given to them, and one of it that was mentioned was that the skill reduction, basically like your one handed sword from 980 goes back to 979 or something like that(its not confirmed if it's just one level, but i think its higher as when the last Salamander that attack Leafa in the beginning said he would not prefer to die as he almost maxed his magic skill level)
Leafa just mentioned a small part in the anime that u might have missed it in this episode, that the dark attribute self destruct magic is really powerful, but the penalty given is definitely much worse than from normal death. Not to mention that the dark magic skill level required to use that spell is damn high(i mean, really high). So i dont think many people will really just waste tons of their times increasing dark magic skill just so that they can get one time use high level explosion.

Hope this explanation helps
