What Anime Du think can really teach to people in real life such as attitude,behaviour,karisma and lot of positive characterisms so that we are earn right to be better human in future though we maybe worst at first.

Prince of Tennis. It taught me many things that we should never ever give up to get what we want to achieve. :3

Natsume Yuujinchou definitely belongs in that category.

Gintama is probably one one of those Anime X3

~A lot of people only see it as a slapstick comedy, domestic violence, a gag show/parody and has rude characters... But if Du would read between the lines you'll see this Anime has a lot of deep life lessons that can relate to just about anyone, no matter what status Du are in life.
