The sequel to the original Trails in the Sky.
Several months after the events of the first game, Estelle has taken it upon herself to search for Joshua after his sudden disappearance in hopes of bringing him back.
However, a secret society by the name of Ouroboros have decided to make their move in Liberl, setting off a chain of events that could the change the face of the nation.
- Armor-Piercing Slap: Cassius gives one to Joshua, as way of reprimanding him for abandoning his family.
- Arson, Murder, and Jaywalking: Estelle expresses a few things to herself after Dorothy gives her a photo that shows Joshua working with the Sky Bandits.Estelle: Joshua, you idiot... Doing crazy stuff like attacking an army base... And your eyes are so cold, like when we first met... And... And... AND WHY DO YOU LOOK LIKE YOU'RE GETTING ALONG SO WELL WITH THAT STUPID TOMBOY?!
- Five Stages of Grief: Estelle during the prologue after Joshua disappears.
- Denial: She tries to think what she experienced was only a dream.
- Anger: After her father revealed he knew of Joshua's past and that he might leave one day, Estelle angrily yells at him and runs off.
- Bargaining: She immediately convinces herself that Joshua simply went back to their family home, despite the clear fact this isn't true.
- Despair: Falls to her knees and cries after seeing Joshua is nowhere in their house.
- Acceptance: She accepts Joshua's absence, but realizes there's still hope in finding him.
- Gameplay and Story Integration: The party is not exempted from the Orbal Shutdown Phenomenon, and whoever wants to use their orbments - or, in Tita's case, any of her weapons besides the Gatling gun she uses in one of her S-Crafts - during chapter 8 is forced to use a Zero Field Generator to disable the Aureole's effect.
- Interface Spoiler: Taking a close look at Renne's health during her stay with group shows she has a high heath bar, which foreshadows her true nature much later.
- Lotus-Eater Machine:
- As Estelle and her friends find the source of the fog covering Rolent, they are engulfed by a spell from Luciola. Estelle wakes in front of her family house with her father and suddenly-alive mother and turns into a child, spending happy times together. She manages to get out of it when she remembers Joshua's harmonica song.
- As it turns out, the Aureole itself gradually became one. Its effect was apparently akin to being high on speed and acid simultaneously, sans physical side-effects, and the inhabitants of the Liber Ark became so addicted to it that birth rates fell and society began to break down, forcing Celeste D. Auslese to seal it away.
- Plot Tunnel: When you get to Chapter 6, the party conducts a raid on the lakeside laboratory that ends with Estelle being abducted by Ouroboros. Estelle spends the rest of the chapter escaping from the Glorious while reuniting with Joshua. And then the towers are turned into Eldritch Locations, meaning you spend Chapter 7 either on the Arseille or in the towers. You lose access to the Bracer Guilds entirely until chapter 8, and even then, you're going there out of necessity to deliver Zero Field Generators since all orbments in Liberl and southern Erebonia have been shut down by the Aureole.
- Required Party Member: This occurs frequently over the course of the game, starting with the fact that Estelle must always be in the party.
- In Chapter 4, Scherazard is locked into the party during events in Rolent. During one forced encounter, Kloe and Tita are also locked in.
- In Chapter 5, Agate is locked in for the start, Tita is locked in for the middle, and then both Agate and Tita are required for the end.
- Midway through Chapter 6, Kevin is a forced party member for a dungeon.
- From the climax of Chapter 6 to the end of the game, Joshua is a mandatory party member.
- During the Plot Tunnel in Chapter 7, the second area visited requires Zin, and the third requires Scherazard.
- The Jenis Royal Academy sidequest in Chapter 8 forces the party of Estelle, Anelace, Kurt, and Joshua.
- In the final chapter, Josette (who unfortunately suffers from Late Character Syndrome) is required to be in the party for a dungeon, but can be replaced before The Very Definitely Final Dungeon.
- Surprisingly Realistic Outcome:
- The protagonists will be affected by a disaster involving the technology they use failing, and as such need to equip Zero Field Generators in order to use arts. Tita in particular needs a ZFG, as the only weapon she has that doesn't use orbal power is the Gatling gun she uses in one of her S-Crafts.
- One sidequest involves rescuing miners trapped by their elevator failing due to the Orbal Shutdown Phenomenon, Tita restoring the elevator's functionality using a Zero Field Generator. However, as one LPer pointed out, just because the elevator now works doesn't necessarily mean it works properly. The ZFG doesn't restore full power to the orbment, meaning the elevator's movement is pretty much start suddenly and stop just as suddenly, over and over again, until it reaches the top or bottom, resulting in a horrible stomach-churning journey in and out of the lower level.
