@Vasqueztion if he is from a family with enough power and background its not that strange that he can overpower a simple princess, still more if the country is in crysis and he has the military power.
So we have a tale about how the betrayed man tried to destroy the world who rejected him... i have a idea, lets go mistreat the person with the same power that sounds fun!!!
Oh man not only Katai-kun will be heart broken, the chess girl that likes him will go down indirectly too, starting to think that Tadano is the antagonist
These power scale are really messed up, meliodas was with his power sealed at this point in time right ? And escanor won against Meliodas when Meliodas was trying to kill him, i'm really confuse right now
