It's more than wholesome. I cannot describe it perfectly but combine all shounen anime and throw it out of the window, then throw your brain also, until you hit the serious episode. this character development is one of its kind, Gintama begins when the main character is fully developed, so he mostly overpowered in being, so bear and watch Gintama and slowly your human with will rise and your soul will resonate. Slowly and steadily you will be somewhat like me now happy and content with anime but still, don't want it to end.
