1. I'd target girls from around ten to twenty-five. No preference for ethnicity or nationality so long as they're attractive. I prefer the innocent and smart girls, and those with relatively decent lives.

2. Anything that draws blood; guns, knives, arrows, etc. The only exception to that is burning, either with actual fire or boiling. Deaths would be relatively quick, as I'd lack the patience to torture someone for hours or days, but most of the time not instant.

3. Locks of hair from each victims. Panties and an ID card, if possible. All buried in a box somewhere.

4. Something with "reaper" in it.
