Rei is requesting...after all that nonsense with clothing and disguise in her log? A ring (presumably Dark Typed) that creates an illusionary disguise, similar to Sailor Moon's Disguise Pen from canon. She's still Rei underneath it, and sounds like Rei, so it's limited to her knowledge and gender.

Yuuna will, despite her best moral judgement, request a Dark-Type talisman/necklace to shield her mind from psychic control type things...like Void's Hideous Laughter.

Yukiko declines any reward, unwilling to accept anything from icky necrodouches.

Lucca: does this. And then requests a sponge.
