Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Target 1 "HERO" Fusion Monster you control; return it to the Extra Deck, then Special Summon from your Extra Deck, 1 "Masked HERO" monster with the same Level as that monster's original Level, but with a different name. (This Special Summon is treated as a Special Summon with "Mask Change".)
