I don't remember anything but this one scene.
There is a shrine or temple and someone is carrying boxes. They trip or something and these beads fall out. The beads do something that makes the character crazy and not too far off is a couple people reading under a tree. Then a fight breaks out.
The Shrine/Temple was not the main setting of the anime and one of the people under the tree was maybe a little girl.
I believe the person carrying the boxes was a girl with purple hair and the beads were some type of jewellery. I think they were absorbed making her angry or jealous to the point of fighting someone at/near the tree.
I want to say it was a fantasy type setting but I don't remember monsters or such however there is more fighting with magic or magic like abilities.
I watched it only a few years back maybe like 2013, but I'm not certain though it had a "newer" art style.
