I thought I was the only one, she's annoying and just in the way
It wouldn't even be as bad if she only was a plot device for a bit to get between them and their "romance" (which is nonexistent anymore apart from bait panels now and then).
I find her unbearably annoying due to the manga changing into some kind of humiliation play since her introduction. He literally improved and was told so multiple time and now we have him suddenly be a bottom 5% player while the girl that never played before is a god. He also gets insulted, treated like a horny beast "as a gag" (not funny even once) and pampered like a fragile little kid that sucks at games.
This is lame. Not even the ultra huge amount of fanservice since her introduction can redeem this shit.
