No, you are wrong you, Kirino was popular with the incest fandom, Kuroneko and Ayase were the really popular ones and I base this on the cosplay contests of their time, all the girls were Kuroneko or Ayase(knives made of metallic paper and red stains on their clothes), you even have the PSP game I repeat, that game came out complaints of the horrible ending and even Kirino's own fandom was angry about the ending, everyone was angry.Actually, you are wrong; the Kirino ship was popular, it was just that at the time, people thought there was going to be a twist where they weren't actually related OR the author would have guts and make them get together.
And the PSP game had a better ending because they actually got together. Author was in a dilema because both of the endings he wanted weren't allowed by the publisher... his publishing group was too PG for incest ending and the twist he was relying on (one he used for the PSP) was banned...
And even IN the light novel, the author literally explained that he wasn't allowed to do the "they aren't blood related" twist any more (which he fixed for his next series).
In fact, the anime ending was something people looked forward to even after the LN was released and people knew the ending.
And your explanation for NTR made no sense because the girls would have never even met Leon so they weren't NTR'd
They ended up together and then split up, how do you say that was an ending anyone wanted to see?
Don't lie, the author's ending was Kirino's but separated, because his incest fetish was so weird and in his next work he showed how sick he was to the point of making things right and lying with his "younger sister", i.e. he is a complexed incestuous without a real younger sister, I mention this because for a reason he is compared to the author of bakemonogatari in shady fetishes!
As far as I remember in his next work, if the one I think it is because there was a very similar one, they were not real siblings, they were step-siblings, I don't remember and there are manga and novels that pass that law up their ass, Mahouka is the example that is not even afraid to insult China, his former commercial buyer(insulting their government cost them popularity there but the incest of God onii-sama was superior to China!)
People expected him to stay with Kuroneko or Ayase, Kuroneko being the healthiest relationship of the women I knew, Ayase was spoiled and I was afraid that her backstabbing games were real....
Your argument of it's not NTR is why I make fun of marietard, why do you think Leon never met the queen...or spent time with Noelle or Louise...because he was going to prove the falsity of his "loving" relationship with marie. And of course it's NTR, only a marietard would say such stupid things, if you read the real novel and then read this garbage, you will say it's not NTR? Also, it's NTR here because Leon will marry the villainess Angie, and she already declared that she hates him and will marry him by obligation of her family, it makes me laugh how that fandom of idiots say crazy things about Leon being the ugly noble of the camp BUT they don't want to mention that Angie is the noble girl that Leon mentions in vol 1, that if he marries one of the "horrible" girls of the academy, she will force him to take care of the child she has with his lover! Or will you tell me this is not real?
Pff, the only thing that matters about this crap is vol 12 that shows its ending, and then all the marietards will understand that the author always planned to tease marie this way, just knowing that Arcadia exists and is under the empire's palace, is to laugh at the people who think this will have a happy ending hahahaha.
