richter abend - her beloved master. although centurions were previously conceived to be incapable of love, aqua is quite taken with her half-elven master.
tenebrae - spiteful tenebonehead. they’ve known each other far too long and aqua just can’t stand to be within his presence for more than mere moments. she finds herself yelling at him for every little thing.
emil castangier - although technically enemies, aqua shows a decent amount of kindness to emil. whether its because she understands his origins or respect in his friendship with richter, she’ll never really say. but she’s rather willing to play friendly as long as emil doesn’t get in richter’s way.
marta lualdi - richter’s initial target of choice and therefore aqua’s opponent as well. she dislikes marta’s loyalty to ratatosk but will only be caustic towards her on richter’s order.
