I can relate to that. But I don't think Nodokathon is merely a fan-service. Nodoka elaborated her intention in detail here.
As in, she's trying to "break character and shell of everything" to save everyone from given inertia and inanity. I believe in Chandler's Law she talked about same thing. Nodokathon is no exception, all part of her experiment to find more intriguing aspects of character to help her understand and distort the world. It might seem to be selfish as always, but before Futaba, I don't she has ever taught to have a self. She's just trying to break artificiality perceived and taught by her mother who unfortunately the sole comfort she had in childhood. And, I repeat again, she's not vile. It's a matter of perspective
Truth be told, I apologize beforehand if it sounds too terrible but LiL is a terrible game in every sense of the word, don't you think it's awesome to shatter Io's facade into pieces before everyone else using logical intelligence? There is something extremely gross yet utmostly beautiful in cruelly revealing and exposing truth and scars. Like This Town Has Two Halves. It's better to keep that a speculative thought, though. Don't do harm. Life is not a game, which is exactly the problem Nodoka has, warranted or not.
