This appears to be an original game with original characters. I found this on rpgmaker.net on a day I was extremely bored, and had free time. And it surprisingly cured my boredom that day.
There are 3 games in series, so I will list the names of the games, and the plot and information defined by the author, and i've only played the first game on the independent story so ya...
Platform: Rpg maker 2003
Genre: Rpg
Alter A.I.L.A.
http://rpgmaker.net/games/268/"Alter A.I.L.A. takes place in a post-apocalyptic world, on a remote plateau: one of the last remaining land masses above sea level. You play the role of a young prisoner, who among others, have had their memories erased, and must now fight for their lives everyday for the entertainment of others. From here, the story can go in 3 separate directions, depending on your choice during the prologue.
The 3 Sides:
Rebel: On this route, you'll join up with a rebel faction created to stop the dictatorship of Kugar, the overlord. Your motives are ultimately summed up in overthrowing Kugar and establishing peace and human rights for all.
Imperial: On this route, you'll support Kugar's regime, and work towards crushing the rebellion. All resistance must be terminated.
Independent: On this route, you won't join up with either side. Whoever rules does not matter to you. Your one goal is to be free."
Alter A.L.I.A. Genesis
http://rpgmaker.net/games/272/"Alter A.I.L.A. Genesis takes place in a post-apocalyptic world. You play the role of a young man known as Leon, who seeks to survive in the harsh environment he is brought into.
Exploration is done mainly via a side-scrolling view. In certain areas, an exclamation mark will sometimes appear, indicating the presence of hostiles. Press Z when this happens to initiate battle, or wait to let it pass. Sometimes battle will be unavoidable. When walking, enemy encounters won't occur.
The battle system revolves mainly around each character's Abilities, which are a set of commands specific to that character. Abilities require AP and EX to use. AP is gained every time a character takes a turn. The default is 2. EX is gained every time a character uses an Ability. The default is 1. Note that this may change depending on the situation."
Alter A.I.L.A. Variant ( PLEASE NOTE: The author decided to make this game into a comic instead for reasons unknown to me. I believe this is the last in the series. It seems the beta or demo he released of it will still remain there)
http://rpgmaker.net/games/2994/"Alter A.I.L.A. Variant takes place in a modern world, 3 years after the events of Alter A.I.L.A. Genesis. 2 years ago, a great war came to a decisive conclusion thanks to the efforts of a small band of people. Peace should have followed, but there are those who would choose to continue fighting. This is the continuation of that story.
