Liszt
She's known for her philanthropic work and genuinely seems to care about people. Love is basically her whole thing—it drives what she does and how she sees the world.
The details of her past are a bit unusual. Originally, when Liszt first came into existence, she was male. Somewhere along the way that changed, and she's now living life as a woman. She doesn't make a huge deal out of it.
When it comes to relationships, she's devoted to Kanae, who she affectionately calls her kitten. She's apparently the only one willing to help cover Kanae's rent, which says something about how much she cares. Fans often note this protective, almost parental dynamic between them.
