I do not know about anyone else, but I really like the character 'Tora' (the blue haired girl who wants your stuff). I think she should be made into a potential future companion you can recruit. I would use her all the time and get her to rank 50 ASAP.
It seems like she stands out enough with voice, personality, profession and whatnot to only wrongfully be cast aside as a nobody. It would surprise me insanely if that making her a companion is in the near future. But just incase she isn't please consider it.
Thank You.
