I would get to the point first:It is about timeskip on anime.All popular anime have a good way of presenting their timeskip.
"A timeskip is a narrative device that is commonly used in the telling of epics or sagas. It allows the storyteller to quickly age characters or develop events without getting slowed down in irrelevant or uninteresting details."
Don't You think all popular anime use one formula to suceed or promote their series??
I will get my ass kicked seeing same formula used by all popular anime.
