Cardcaptor Sakura. It's one of my favorite anime, but I'm sure that people would think that's strange.
I feel ashamed and dirty. Not in a good way. Just bad. Very very very very bad.
Same thing as this anon.
Except I call it Aldnoah Zero.
Don't misunderstand me, I'm not saying I liked this shit. I just had a hard time looking my sister in the eye for a couple days after finishing it.
I'm not ashamed of watching it but I am ashamed of liking it because of the awful fujo fanbase.
I unironically sat through SEED Destiny at one point, so that.
In public? Everything, I hide the fuck out of my powerlevel.
On /a/? There's actually an embarrassing amount, my most recent indiscretion was "Seikoku no Dragonar" though. I watched up to maybe the tenth episode or so.
If you haven't heard of it, it's like Zero no Tsukaima only worse. Infinitely worse.
If you haven't heard of Zero no Tsukaima, you've lived a sheltered existence on /a/ or you're a fucking newfag.
