Natsuki Subaru, an ordinary high school student, is on his way home from the convenience store when he finds himself transported to another world. As he's lost and confused in a new world where he doesn't even know left from right, the only person to reach out to him was a beautiful girl with silver hair. Determined to repay her somehow for saving him from his own despair, Subaru agrees to help the girl find something she's looking for.
I expected a light anime but this one ended up being a quite heavy one. Watch the first 3 episodes and if you don't like them then drop it. If you choose to go on then be ready to potentially have to struggle. The first 2/3rds "good" because of the alternative approach & some other things (e.g. some clever statements/remarks + good pace), the last 1/3rd was a bit "bah" (no final big commitments from anybody, no confirmations of alliances, no hints about hidden agendas, etc...). In general probably not bad to watch at least once. Graphics constantly quite ok, characters are good, some action scenes in 3D with higher fps.
