I do think the Legendary Hero plotline starts in a fairly fun place

where your father takes you aside like "Listen, my son"

"I must tell you of the ancient prophecy"

"When darkness covers the world, the Legendary Hero will come to deliver us from evil"

"And you, my son"

"have to find him and tell him to solve all our problems"

"You must find the legendary Zenithian Weapons. And give them to him"

I found and took up my father's sword, then one town later I found a sword that has 2 more ATK

so now fuck my father's sword
