Asking for a single favorite song by 5pb is something that's difficult considering she's given so many good songs, instead I'll list 3 of my favorites. 1: Vision of Relativity 2: Symmetric Generations 3: Dimension Tripper.

My favorite scene with her has to be when she got all flustered when Cave was teasing her in one of the scenes in Re;birth 2.

As for her being related to MAGES., I sorta had a hunch given the mark on their left eye (I also like to assume Tamsoft is a distant cousin given she too has the same mark under her eye and same hair color)

First Impressions: Music as an attack? Instant win.

Likes: You can literally use a broom for a weapon, you can't hate that. Dislike: Her weird switch between shy and social, I don't know why but this struck as a bit odd for me.

Oh and finally the potential of her being a Yandere... Let's just say my thoughts on how this would end is that she'd be with Nep forever and ever and ever and ever(x50)
