First anime:
Doraemon, probably. That series was everywhere when I was little.
First anime I actively followed on TV was Saint Seiya though, but even then just because it aired right before Kamen Rider.

First anime watched fully:
The King of Braves GaoGaiGar. Super hype and intense mecha show. I remember hunting down all the CDs over a few months, since the TV broadcast was cut short.

First fansubbed anime:
They Are My Noble Masters. Butler comedy with tons of fanservice. It's an adaptation of a VN and covered only up to the end of the common route, so it cut off before any romance could develop much. Still gave a decent conclusion to the MC's character arc though, so that's something.

First waifu:
Kaname Madoka. Still my only waifu.

First manga:
Doraemon, more or less because my family wouldn't let me near any other manga up until middle school.
Aside from that, Home Tutor Hitman Reborn. Was super popular over here when I was in middle school. It's a Shonen Jump comedy series about super-powered "mafia" that got super serious as it went on. The middle arcs were kinda weak but had lots of cool characters, which made the DS fighting games covering those arcs the better ones of the bunch. Then the very last arc ended up being the funniest while also being the most serious. It's weird.

First LN:
Shakugan no Shana. Unfortunately the publisher released only up to volume 14 before they went under, and I never continued it since. Anime season 3 supposedly covers the rest of the series fairly well and I've been watching that on and off, but I'm thinking about getting the rest of the LNs some time soon.
