Awesome!

Being killed would tend to release someone from their moral grounding.

Interesting twist, I just got finished watching the abridged version of Gantz so a more serious take is an interesting change of pace.

the things I would do to see this thing fleshed out.

This is an awesome idea...

This sounds like a fun little adventure... for L, not Light. Mwehehehehehe...

Haven't even started on Gantz yet, but this kicked my **. Great Job, as always.

Just perfect!

xD YOU'RE A GENIUS!

The black blocks replacing the quotes are distracting, but other than that, it's an awesome start. I've never seen a futuristic AU/cross-over before... though, now that I think about it, aliens and L just seem naturally pair together, in an odd sort of way. XD

There are black blocks in your fic.
