An excellent student! She's respectful, passionate, asks questions when needed, does her work on time... a joy to have in class!
But, ah... she feels Agatha's pain more than Agatha will hopefully ever realize. She wishes the best for her.
Tulippa's backstory is all too familiar to her... Mycena wishes she could do something, to at least answer her questions, but she knows there's too much at risk. All she'd be doing is putting an innocent person in danger. It's better that she never know enough than too much.
Her girlfriend... or, ex-girlfriend, she supposes. Externally. Mycena was - is, really - the love of her life, and someone Aranaea loved to spend time with and dote upon. All Aranaea wants is for Mycena to be okay, and she's working hard to ensure a future where Heaven College can't keep them apart.
One of her closest friends. Remaelius doesn't judge and always cares... they're always willing to lend an ear and a comforting smile. She feels bad for burdening them, though... they're already carrying so much weight as-is.
A being who was trained by Heaven College to harm others and convince students that all monsters were evil. Mycena pities Anthuria and hopes that she can help her in some way, even if admittedly she's afraid of seeking her out in person...
Mycena is just another professor to Anthuria, though one she's heard a few interesting words about from other labyrinth denizens. Supposedly she was once one of them and now seeks to liberate everyone... Intriguing, but Anthuria isn't yet sure if that would disrupt her lifestyle or improve it.
