....now that I think about it, we haven't seen Kaede's mother, have we?
We have a slave mark to completely control mages.
A father that doesn't interact with Kaede.
A underground prison for bad children.
...Kaede accidentally killed her mom, didn't she, and neither she nor her dad ever forgave...
Alright I know you have a grudge against the game developers for killing the mamas in various brutal ways, but I don't think you need to take it out on the protagonist...that much for the future where he kills Mania.

Also that mother would probably hire an assassin to make Abikura disappear
