Funnily enough it was actually school days
I am embarrassed to say this, but it was SAO. Luckily, I had some taste back then so I saw Death Note and a few other good shows back then. And now, I am constantly disappointed with people I know because most of them don't even know what Toradora is...
Re:Zero followed by Assassination Classroom
Well I kinda already had a history with anime due to stuff on toonami and adult swim, but what really got me hooked was watching Ranma 1/2 pretty much.
It was basically the first anime that I watched subbed and then after that I just started seeking out more anime on the internet because 2006-Otakaiser was totally unaware that you could find entire anime series and stuff on the internet. An entire new world just suddenly opened up for me and then I started to spend countless summer nights just binge-watching anime. :u
Bleach, when it barely had arround 25~ episodes, a friend came to my house to lend me that new Simpsons DS game and also told me about Bleach lol it was funny who i didnt care about anime at all
Attack on Titan, back when the craze for it was high; saw it mentioned in some places and decided to give it a shot xd
Similar to Otakaiser growing up with toonami and adult swim, but like Nashor Bleach is what really drew me in.
Ranma 1/2 it pretty old school but I enjoyed it so much which got me really into anime from there on.
Probably Inuyasha or Dragon Ball Z :O
