Don't recall too much about the show except for several things:
The anime opening was really energetic and sung by a male who stated sometime in the song "My home" with it being stressed
One of the main characters goes blind, he is a swordsman/samurai
There is one scene where people of the village are committing mass suicide with the promise of heaven for those who do. In this scene, a young boy attempts to commit suicide when he stopped by a young girl who asks him where he's going. In response, he says, "I'm going to heaven Sara"
The opening song of the anime was in Japanese but the anime itself was dubbed. I can't recall too much as it was 10-13 years ago, when I was only about 5 years old. But I remember those certain traits of the anime very clearly. Would very much appreciate an answer :)
***So I'm not exactly sure how accurate this recollection is BUT if I'm right it might help in identifying this anime. If I recall correctly, the swordsman that became blind had orange-brown hair.
A little addition to the music video/opening is that it was pretty dark, lots of shadow effects.
