Looks like one of tomorrow's downloadable quests "Maoh! The One Horned Maoh!" will be one of Dengeki's own ideas. The monster looks like Diablos and defeating him will give you the materials to make a male only "Diasolte" armour set that gives you "Fire Resist +2 (?)" and "Wind Pressure Resist (Great)".

Not really looking at the armour, just that hammer...
