I don't think it is. Usually, such stories are fictional creations for entertainment purposes.

Well, without having read it, it could be that the revenge angels are on a mission to right the wrongs that have befallen their mother. Maybe their mother was wronged by some powerful entity, and the angels, with their special powers, are out to make things even. It might also include elements of family loyalty and the struggle between good and evil in the context of their revenge.

I'm not sure. It might be inspired by real events but could also be purely fictional.

Yes, there can be. Sometimes real-life events inspire such stories.

It could be that someone wronged his mother seriously. Maybe it was an act of injustice like someone cheating her out of her inheritance. So, in order to make things right and seek justice for her, he decided to take revenge.

I'm not sure. It depends on the specific manga you're referring to. There could be various plot developments and character relationships that determine who it is.

He might have felt a sense of relief at first. Finally being able to do something about the wrong that was done to his mother could have given him a momentary peace.

Well, without more context, it's hard to say precisely.

It could be related to personal vendettas, like if someone hurt her child or violated her family's safety in 1993, and she decided to retaliate in some way.

Yes, it was. The story was inspired by real-life events that took place in 1993.
