Im not sure if these are 2 separate anime but I know there's this kid who gets sent back in time I believe to samurai era or something like that and its not the ecchi one where they're all girls. (I've googled it before coming to ask you ladies and gents.) and I think there some super powers involved not too sure there's a big fight on this bridge and I think a girl saves him or he gets strong and saves her I cant remember, aww thats all I can remember oh and there are some samurai from that era that get sent into the future and theyre all confused but that may also be a separate anime but I cant google it for shite.
