Below is a walkthrough for the Promise to the Future hero quest in Xenoblade Chronicles 3. To obtain this quest, you’ll need to level up the Lost Vanguard class to rank 10 and then have Monica in the party. Head to the ? in the City to trigger a cutscene starting the quest. We did this in Chapter 7 after completing the Side Story: Sena hero quest.
After accepting the quest, make your way to Michiba Canteen to trigger a cutscene. Afterwards, head to the Residential District in the southern part of the City. Next, travel to Corne Island in the Cadensia Region then make your way to the objective on the eastern side. When the cutscene concludes, drop down into the pit and join the fray. Defeat the two Level 61 Anti-Candidate Antols. Once you’ve completed this task, the quest will complete as well.
