Masa and Mune are 2 little devils that you have to beat to get the Legendary Masamune but first things first.... you'll need Crono, Lucca and Marle (it won't matter which level you have them at but make sure your HP is high enough) also bring along some Mid Tonics or use Marle's Aura Whirl Tech to restore some lost HP.. they don't have a weak point at this point but if you use Provoke, they'll get a little cloudy (Chaos).. also if you use Lucca's Hypno you can put them into La La Land (Sleep) then just attack them as you would usually do (physical attacks) the first part Masa has 1,000 HP and Mune also has 1,000 HP. Then Masa and Mune will fuse.. The Fused Masa and Mune has 3,600 HP when he is "Storing Tornado Energy" use Crono's Slash attack to neutralize the tornado.. Thus, letting you attack him but if you fail to stop the tornado he's gonna nail ya meaning he will attack with a Slash attack of his own. The rest is pretty straight forward.. For defeating Masa and Mune you get 500 Exp. Points, 10 Tech points and 1500 Gold and the Broken Masamune (I think it’s just the hilt)
