Fun Fact: Neo 2.0 (and also NEO Diffsinger) sticking their tongues out is a reference of one of Hioka's earliest art for Neru
Never really like Neru sticking out her tongue for the Neo art and even learning that it's a reference to some of Neru's oldest art still doesn't make me like it. That being said, it's still a neat reference at the end of the day worth sharing.
Side Note: I came across this when I was looking for old Neru art and in the process, I came across a period of time when there was a more Neru-Miku fan art than Teto-Miku fan art which is a really interesting thing to observe when compared to now, especially since this was also pre-Triple Baka which is really neat.
