Mamoru is the NEET sibling who always claims is too busy to help you with your homework, but always has time to go grab lunch or mooch off your dinner plans. If I had to guess Mamoru’s actual position in the guild, she still cares for everyone as fellow guild members, but might be considered a “defiant” one since much like her creator, she is willing to have an opposing view and not just mindlessly agreeing with the majority. Granted unlike her creator, Mamoru does this out of usually legitimate concern and caution as oppose to her creator’s desire to create chaos and drama.
