The game also features a gacha mechanic where players can summon characters from across the series to join their party.
Langrisser Mobile provides examples of:
- Beach Episode: The event that made Feraquea a playable character centered around Hein setting one up on a deserted isle, which just so happened to be where Feraquea was establishing her base.
- Breaking the Fourth Wall:
- In side-stories and when new modes are unlocked, the characters sometimes make jokes about being in a game; for example, when unlocking player-vs-player fights, Amelda is glad it's her turn to give a tutorial.
- Amelda flat out says Estelle and Joshua are from the game Trails in the Sky after meeting them.
- Crossover: There have been numerous crossover events since launch, which includes Guest Fighters that could only be recruited during those times, such as Bracers and Ouroborous Enforcers from The Legend of Heroes: Trails in the Sky, three ladies from the original Sakura Wars, and the main male protagonists (plus the Toguro bros.) of YuYu Hakusho.
- Doomed Hometown: In Chapter Eleven, despite General Bodamicus' promises, troops from the Hebril Empire raze the heroes' village and the team needs to help evacuate the survivors.
- Level-Up at Intimacy 5: You can Bond with units by giving them gifts, which unlocks new battles, voice clips, and permanent stat boosts (though the latter also requires secondary objectives be met, such as obtaining a specific class, or completing a specific battle with a different character they have a connection with).
- Play Every Day: The game has a stamina meter for selecting stages that refills over time, as well as daily missions that reward players with additional experience points and chances to summon heroes.
- "Rashomon"-Style: Cherie's Bonds missions are a retelling of Der Langrisser from her faulty perspective, such as replacing a lecherous old man with an octopus.
- Shout-Out: In the English translation, Hein claims that the sky cracking when the player unlocks the Dimensional Trials is "according to keikaku".
- What If?: Some special events take this approach, with the most notable being one in which Elwin becomes an overlord, as it introduced two new units (a Young version of Jessica after a recent death and reincarnation, and Emilia, Vargas' daughter who's now leading a rebellion).
