Bug and Fix Edit
Using Dragoon form in this battle may lead to a game crash. It is confirmed that this can happen on a second playthrough, but it is possible that it may occur on the first playthrough. It is confirmed that not using Dragoon at all in the battle will fix this bug; it is confirmed that it is possible to use Dart and Shana's Dragoons in a party with Meru during the battle, as long as all party members are in normal form at the end. This is not the only such bug in Legend of Dragoon; in the event of a game crash elsewhere in the game, it may be possible to use this same strategy.
