[@Rockin Strings] Nope, shes eldritch. 

[@Xaltwind] If she has always been a 'free' spirit, as I assume she acted something like this before the loss of the creator, then while she acts bubbly and ditsy, she is scarily good at her job xD. Otherwise she wouldn't be a vault keeper. I haven't shown it yet, but she does take that job seriously. BTW, she does take orders, she just acts like she doesn't, or acts very chipper about it. 

I can honestly see the other chapter keepers rarely ever seeing Light serious, probably because they don't watch her stalk people who invade the vault xD. I can see Graft knowing about her serious side though, some of those traps have to be bought from him I'm sure xD.

... Crap, I forgot to have her ask Graft for new sawblades come to think of it. too late to edit now. xD
