After reporting back to the Matriarch, the Sacred Flower Festival will be underway. However, just as everyone's enjoying themselves, the imperials come to spoil the fun. Our heroes won't have any of that though and a brawl breaks out in the streets.
You'll be fighting an imperial trio consisting of one Guardsaxe and two Guardspears. The axeman uses Double Damage to dish out big damage, while the spearmen may trigger Second Spear for a second hit. All are weak to lightning, so zap them and zap them hard.
Succeed and a string of cutscenes will ensue. Eventually, the chaos will pass and you'll be left off in front of the main stage in the plaza. Attempt to exit the city and our heroes will receive a sudden invitation to visit the secret Sagitta village.
Note : The next sidequest, Valkyrie vs Monk, will unlock when you return to the world map. Seeing as Alternis is helping to keep Florem safe, you've got plenty of time to see what silliness awaits back at Florem... and we can assure you: it's pretty silly.
