Yeah, absolutely the best; she'd be an great ntr-antagonist, she has diffenently the right mindest and skills.
But there’s still a chance that Fujino is building that harem up on purpose, just to have them all fall to the council in the end with some bs excuse. So let's enjoy it for now
I mean, the 'Harem shot' CG is obviously just to showcase how far gone Kirito is now LMAO...even if we didn't know already Liz WAS gonna fall under Inoda's sway too, there is NOT saving Alice either, even if they somehow were able to really defeat the council (Unlikely in a NTR game really), there is no way they fix the brainwashed that makes her into a complete slut, so yeah XD Sinon and Sugu, especially the latter, are the only ones who have any real chance of ending 'with' Kazuto (Most likely in an open relationship behind Asuna's back and WHILE Asuna is still being Inoda's whore without him knowing, which is the only realistic 'win' they could have because anything beyond that would break Fujino's game style as we know, he's NOT gonna let Kirito just happily move on in any ending despite how easy it could be lol).
Also, more than an NTR antagonist (Which the fact she still cares more for Kirito's happiness than her own victory shows she isn't actually that dedicated to sadly, as otherwise she could have exposed Asuna and consoled the broken husk that would remain of her Onii-chan), Suguha would be a great NTR Protagonist, I have always thought she had the best potential out of all the other SAO Heroines to steal Kirito right under Asuna's nose (Living together being her biggest advantage really), but sadly because so many people don't consider Reverse NTR to be NTR (Despite how all attempts of 'NTR' with the non-Asuna SAO girls really aren't, especially Sugu who was actually rejected onscreen XP), so there is basically no content of that at all, except some CG collections made by AI that recently came out thanks to the age of AI art :3
Or Abridged Asuna. SAO fans (like me) usually don't like her lol
Based true SAO fan, I hate the Abridged versions with a passion, especially how all the haters 'brag' that they're "better written" (It really shows the creators were a bunch of haters just thinking they could 'fix SAO' and masking it as an Abridged Series). I could barely stand what they did to S1 characters, but seeing what they did to Suguha was what finally made me drop it, because it REALLY showed they were just writing what the haters thought was 'better written' SAO rather than actually making jokes for the sake of being funny, the amount of scenes they had to remove from Fairy Dance just to completely erase any and all traces of Suguha's feelings for Kirito (When with Liz and Silica they kept them but made them into shittier jokes) and replace it with the complete opposite instead (Her being not only awful to her but the source of all traumas) just because "incest is bad and her character would be better without it" was beyond obnoxious.
