Hero and Aero are just one of many that became prisoners on Earth upon thousands of years ago.
It's simple really, they helped exterminate an entire planet and the race that was living there, in complete revenge because of what had happened to their loved ones on their own planet...Which is what they, as Unigals, don't do. Unigals don't bother to feel and use their emotions in their lives because it makes life harder...
So, now that they are now stranded upon Earth as punishment, they had gone through a lot considering that they get continuously reincarnated after they die.
Upon prisoners that kill themselves, they forget what they are in prison for, but for Hero and Aero, who remember everything and not up for 'parole' anytime soon, it is a story to tell indeed!

There were times of fun, where they could laugh without worries and forget where they were, but there are times where they are separated as great friends.
Feeling feelings, brought up to be told that they were wrong, really did not help Hero and Aero explore beyond friendship and so they drifted apart, in a bad way...
Coming to modern day Earth, they meet again...
Through a helpful way of just making a game, they explore their bond once again after all this time…Are they still angry, upset? Have they forgotten? Or is that bond, that closeness and feeling still there? Does it help now that they are Unigal ‘right’ for each other now or…
