Oh wow... I don't know if I can finish Digital Devil Saga 2...
THAR BE SPOILERS AHEAD!
So it turns out your characters were creations that Sera made up as company based on people she met in the "Real" world which you are now in to keep herself company while she's sealed up since all she's really being used for is to talk to "God".
So the first dreary thing that happens is that you learn people, whether they be infant or old in age, are being thrown into grinders and used to feed the people of the Karma Society since they're infected with the demon virus.
Next something odd and somewhat funny occurs when an old woman, in response to hearing her colleague say she wants Sera killed and dissected, asks how she can be so cruel and states Sera was made of her "...own sperm and egg." WTF, right? Well, in a conversation you learn that woman is a hermaphrodite.
Then the deaths happen. Wanting to protect Sera, Heat charges at Serph, the main character. Serph does nothing and get Heat's arm straight through his chest before grabbing him and they both fall into a pit. Killing off the MC? Not cool.
Next, a big scary monster is after you. Roland goes after it and Argilla goes to help. Argilla finds the monster munching on Roland and attacks. She had no hope. The two die but take out the monster with it.
So now I'm down to three characters, one of which I neglected, so I had to majorly grind. Next it turns out Serph is alive and well, but you learn a really sad truth: The person Sera based him after was a total dick. It turns out real Serph manipulated Sera with fake kindness to get her to do his bidding, not caring that the experiments were killing her. While the real Heat tried to stop it Sera hears the real Serph tell him that Sera is of no importance and if she died they'd just get another child and has the real Argilla shoot and kill the real Heat. Needless to say, Sera is devastated, and that's why the world is so messed up because her sadness upset "God".
You with me so far? I didn't think so.
So now I'm near the end and it turns out Sera is going to die soon due to all the experiments done on her. It's really upsetting to see so many characters you've gotten attached to bite the dust and I'm not sure what sort of ending I'm in for.
