The Legend of Heroes: Zero no Kiseki (Trails of Zero) - Boss 17
Yet further into the Fort of the Sun, we finally find Earnest, the former secretary to Elie's grandfather. The man is beyond all reason at this point, claiming that Crossbell's about to become a "Holy Ground." Lloyd pushes past this, reading off a list of Earnest's crimes, placing him under arrest. Earnest counters by stating that crime is but a societal construct. He then proceeds to turn into a crazy looking demon himself. On top of that, he calls out two dragons, and thus does the final confrontation with Earnest begin in earnest.
The first thing to do in this fight is to take out the dragonds. They're a massive pain in the rear, especially since they have an attack that can cancel any magic that you're casting. The demon himself comes with Majinken (DEMON FANG!) again, as well as his old S-Craft, which still hurts quite a bit. He also has an attack in which he takes a turn to charge, followed by a leap and smash. This attack can't be cancelled, unfortunately, so your best bet to avoid damage is to cast a guarding spell.
Afterwards, the team presses on.
