Not sure if the other dude is a troll or just that freaking bad, but no, you use the Knight Sword, your first subweapon.
You also need a cross you get from the map (follow a guide, but it's in the very bottom right corner), and should level up as much as possible.
It's quite doable on your first playthrough, and as the first map you play.
To be fair, I got this information from the guide on ULMF, but... that's a damn sight better than ignorantly proclaiming it's "NG+7" without any clue what you're talking about.
