1.) Hikaru no Go\n\n\n\n\n\n2.) Hare+Guu\n\n\n\n\n\nBoth originated from manga, only Hikaru no Go's ever reached the states. You might find it interesting that Hare+Guu's manga is from SqureEnix.\n\nI know...neither of the are the most mature anime's ever, but they really are worth checking out. \n\nGo see!
