The three headed hounds shake the hero world

In the faraway empire where time stands still between past and future lays a powerful clan called "The Baskerville clan!" a clan that prides itself on its swordsmanship and strength above others. It births some sword geniuses and one of their greatest, the Great Vikir Van Baskerville, the famous bloodhound that goes down in both Baskerville and the whole Kingdom's history as one of the greatest saviors to the empire. Following his descendants three almost identical triplets with each individual skills that shake the clan and empire, the three young hounds spend most of their lives in the empire within the clan until they turn 16 when they among their siblings and others are assigned to attend a school call UA in a country called Japan for an exchange program between the country and empire but when they arrive they're faced with arrogance along with getting look down on because they lack what the people have. But that's okay. They'll show that their so-called "quirk" isn't all that determines worth and will put them in their places. Let's see how these arrogant fools will last against the Baskerville triplets!
