When Eren first sees the small figure curled into himself, unmoving on the swing, he thinks it's a hallucination. It is impossible, because the Corporal is supposed to be his superior. He is supposed to be more experienced, more refined, more mature. But now, Eren is staring at that familiar face, posture... On a child. He has to blink to make sure his mind isn't just fucking with him, because it's just not possible. Surely reincarnation isn't playing some stupid trick on him? But the more he stares, the more obvious it is. That child isn't some carbon copy of his former Corporal; that person is definitely Corporal Levi. ...Right?

You've watched the videos, played the games, and have known how it all plays out... But what if you were part of it? What if you were given the chance to be with your favourite Hetalia characters...but at a cost of being with them in...HetaOni? And what if...it wasn't just those nation dorks that all of us love? What if...the Second Players...or 2P!s were actually in all of this as well? And what if...YOU had the key to get them all out of there? Will you keep on going, even if you knew all the sadness, danger, pain...and madness that HetaOni can give you? You decide.
