@ HongNamPhm707 Let's start with Shirou Storm's adventure. He managed to travel across all verses, timelines, spaces, dimensions and etc, before arriving to a place which is "The Promised Land". It is plan outside of everything and beyond absolute nothingness and absolutely anything that exist, existed and will exist and also beyond everything that doesn't exist and will never exist. "The Promised Land"/ Supreme Nirvana / Infinite Eden / Final Heaven... Is an infinite sized verse which has no limits and can expand to an immeasurable and unthinkable degree, and this verse is composed of an infinite amount of verses, spaces, dimensions and parallel universes that are from an atom size to the size of infinity (In this verse, the merest and smallest atom is equal to the size of an Archverse). Shirou Storm at the end of his journey managed to reach the center of this realm, which is almost impossible for even a supreme avatar (which in my cosmology are enought powerful to wipe out all fiction in a matter of minutes). As for your question, Shirou Storm had fight against many powerful foes and manage to beat all of them to have what we can call "Eternal Peace". So we can assume he beat them too, because they would represent several dangers for his plans.
