about mira, I think you should read tower of god.. and see bam chasing after and helping the stupid blonde girl.. you fucking seethe with hatred for her and you end up cursing bam and his stupid 'quest' to 'save' her.. because he just is too obsessed to use his brain and see what and who she really is.. a disgusting, ugly, manipulative, murdering, psychopath.. all for the sake of achieving her goal..
( really do think the author loves her and who knows, maybe the author secretly wants to have all of her inhumane qualities, so she gets all the special chances to screw bam and his friends over.. srsly, she is the most garbage character I've ever read about in any manga, manhwa, manhua, etc..)
it is probably close to what Cirdon is mentioning to you.. if you haven't read it, you really should.. so you know what not to do in a story..
The only reason tower of god is so good is that bam gets stronger and there is so much going on.. all kinds of crazy plot twists and crazy characters.. and the stupid blonde girl isn't in the story a lot.. so that is good..
..but when she is, you really want to impale her head on a pike or just anything..
but no, the author isn't good at dealing with her, and the author even gives her ridiculous powerful allies and items.. and the plot armor is unreal..
in the end, I really believe the author loves the stupid blonde girl..
she was only necessary at first, so that bam entered the tower and probably after a hundred or less chapters she would have been irrelevant, but the author continued bam's obsession to 'save' her for another 2 hundred or so more chapters..
or maybe 3 hundred, I forgot..
but srsly you should read it, and see what I mean about how to not make a hated character
