Haruhiko can't help but admire the shy and beautiful Mercurio. She's always willing to lend a hand, and she's never selfish...in fact, she's Eukanaria's opposite! But why does Mercurio seem so sad and confused lately? It's up to Haurhiko to save his sweet friend (and keep the feisty Eukanaria happy, too). When the time to wield his weapon arrives, will Haruhiko summon the skill to land the final blow...or will he be blown away?
