I've been thinking and thinking about an anime I cannot find since the first time I watched it. It is bothering me that I cannot find it through any normal means of searching.
This anime has a whole bunch of kids in a more modern day. The kids all have swords, but the average public cannot see them. The MC notices the kids with swords but is found out. He is helped by another kid with a word to find out how to obtain his by finding out the error in his life and the next time they meet they will have to fight.
Is there anyone who can help me find this anime or give me some suggestions to what it might be?
