Akin to love, friendship can either be an excellent or horrific thing between peopleーand that goes for fiction and non-fictional characters. Having characters have bonds of friendships makes for a more exciting anime; however, it can also show how lacking the experience can be in the way it is depicted. Not all companionships are lovely, like in a shounen anime, nor are they the healthiest, either.
