Seems like Sousuke Sagara and Heero Yuy... must silence those two before the truth spreads out even more. Silencing Hellgiver is a secondary objective to those two. Sadly I can't skip ahead in visual novels (the only books I read are Drizzt series, Harry Potter, Lord of the Rings, and... and... poo poo, forgot it was called...)

Personally, I hate spoilers, of any kind. If someone tells me what happens, I usually lose all interest in reading/playing/watching whatever it was.
