This is probably the worst, obnoxious, poorly written character personality thats been written in any Anime.
Not only she is, calling the Protagonist (Me), a bonehead, for no reason or context, with her also having a rather childish demanor too, she is also considered to be part of the Six council appearently.
I think the worst part in that is, she is considered the strongest out of the other members of the council six, so this gives you the idea, that no matter what you do, despite her actions are literaly just plain stupid, childish or wrong, she is get to decide or lead/organise anyway because she is the 'strongest' of them all.
I think the rather suspicious part is, she doesn't seem to be bitter like that towards other character, she is only like that towards the player for some reason.
Not to use this stereotype, but this character is rather indeed, a Mary sue. I do understand that Tsunderes are just there probably for a comedic value, but is it really? It's not really funny, I think this character was rather setup rather to just take the piss of the player and making him want to punch the monitor. She doesn't seem to get better towards the protagonist eitherway as I followed the 1st season, I was just shocked that someone like her is in charge of that Tournament thing in that episode in season 1, how did she climb the ranks so easily despite being an obnoxious brat?
This is, what I call, the definition of a Mary Sue, nothing more. I'm sorry to say this, but I would be more than happy if there was an episode part where she is slaghtered by Falspawn, Dark Faltz or the Profound Darkness, atleast the villains are far more believable characters than this brat.
