Well I have a couple to add this this list, that I’m kinda surprised no one has added yet.
First:
Tengen Toppa Gurren Lagann (Action, 27 episodes)
Basic plot. The people of earth have been forced to live underground in isolated villages, having no contact with the surface, for generations. Most are happy living like this, except for one Kamina, who wishes to go to the surface. After another failed attempted with younger villager Simon (main protagonist) a giant mecha crashes through into their village. Kamina, Simon and new friend Yoko, pilot a mini mecha and defeat it before reaching the surface.
Once on the surface they find there are more giant mechs piloted by “beastmen”, who wish to keep the humans underground. After capturing a mech from the beastmen, Simon’s mini mech (Lagann) can enhance Kamina’s mech (Gurren) into the Gurren Lagann. They then set out to defeat the beastmen and free the human from underground. And any other threats that may show up to hold back the Spiral energy of the human race.
Great anime. Good fight scenes, brilliant animation, and great comedy moment too. Especially with lines like “Don’t believe in yourself. Believe in me, who believes in you.” And also how can you beat having a drill (or several huge drills) as the signature weapon of the series. Much more unique than your standard giant mech anime.
Second:
Higurashi no Naku Koro ni (Mystery, horror, 26+24 episodes, two series) (Based on series of computer games)
Is set in the small village of Hinamizawa, in June 1983. The main character Keichi Maebara has recently moved there, and has befriended Rena Ryugu, Mion Sonozaki, Rika Furude and Satoko Hojo. Everything is going well until the night of the Watanagashi Festival, where a local curse strikes again, killing one person and making another disappear.
In each arcs of the anime, one of the group ends up losing it due to paranoia and comits a crime. Which usually involves killing one (if not more of the rest of the group).
The anime is split into two types of arc. Question arcs, and answer arcs. In questions you usually on see one side, and it leaves you with many questions (hence the name), the answer arcs are usually retelling of the equivalent question, in a new manner to see what is really going on in this small village.
Great anime to watch. Really interesting story, and feels great once you watch the second season, and think, of that is what was really going on.
Well anyway there are my two. Hope you enjoy.
