Nana:

Favorite islands, animals, colors: Are these mandatory? They're easy to fill out, especially favorite island, so it's disappointing to see them get skipped.

Duff seems to have rolled occupation and non combat skills into one. She's a very non-combat skill oriented character, with the ability to make/repair robots, cyborgs and explosives, so I'd definitely like to see a lot more detail there. Duff has said some things in chat that imply there are “quirks” to her inventions and abilities that are barely mentioned in the profile. Possible balance issues with a character who can create permanent robotic ally NPCs should be addressed.

One question about the personality I'd like to see answered: She's smart but acts airheaded most of the time. What are the exceptions to this? I'm assuming when she's working on robots at the least, but it gets left unsaid.

Appearance: She's a low ranking marine who explicitly ditched part of the uniform for something “casual”, but I'm willing to let that slide. Duff might want to consider just describing her casual outfit in addition instead of trying to cram two into one, though.

Experience: Lists 30/100 twice in the profile. Is there a reason Duff thinks they can start with 30 experience?

Pabo seems a little advanced, but may be fine. I'd like its mini profile to have either non combat skills, fighting style or both to detail how it assists Nana.

Bombs Away!: Not keen on an e-rank character being fast enough to build multiple explosives, even simple ones, within a few seconds. Cherry Bombs and anything else she uses in battle should be listed as weapons, even if she's the one who makes them.

Not a make or break point, but Duff doesn't mention that Nana's father is a marine until halfway through her history, so I was really confused as to why he was insisting she become a marine.

Possibly ask Duff to work on the run on sentences.
