The Empire of Britannia has invaded Japan using giant robot weapons called Knightmare Frames. Japan is now referred to as Area 11, and its people the 11′s. A Britannian who was living in Japan at the time, Lelouch, vowed to his Japanese friend Suzaku that he’d destroy Britannia. Years later, Lelouch is in high school, but regularly skips out of school to go play chess and gamble on himself. One day, he stumbles on terrorists 11′s who’ve stolen a military secret and is caught by a member of the Britannian task force sent after them, who is Suzaku. As the rest of the squad arrives, Suzaku is shot for disobeying orders, while the military secret, a young girl, gives Lelouch the power of Geass, which makes anyone obey any order. While Suzaku is secretly made the pilot of Britannia’s brand new prototype Knightmare, Lancelot, Lelouch becomes the masked Zero to lead the rebellion to destroy Britannia once and for all.
Just give a quick answer of what animes you've watched in the past that you liked but felt weren't taken serious enough by other anime fans. For me its Shigofumi, I loved this anime and I've rewatched it several times.
You should try Yamishibai I think it's called, they are actually more of a horror rather than just a bloody murder anime. It has a strange animation and each episode is 3 - 7 minutes but there is t much of a story just more about short horror stories of folklore Japan. If your looking for creepy rather than gory, you should really watch this (not all episodes are creepy)
Another for classic horror (dark lighting, soundscapes, mood, etc.), Blood-C for a gore-fest, School Days for a depraved acid trip of a story, No. 6, Future Diary, Mirai Nikki, or Tokyo Ghoul for something with an actual plot.
This anime was pretty good but I still haven't watched the last episode though. The last episode was delayed a bit because it didn't fit the time slot or something and so I just kinda forgot about it...
