History YMMV / ArNosurgeOdeToAnUnbornStar

** [[spoiler:Nay]] also qualifies for this, as she hits pretty hard, is hard to get rid of the mooks protecting her, and between her attacks and those of the enemies accompanying her, it's very easy to end up creamed in a couple of turns.
* TrueArtIsIncomprehensible: Kanon [[SugarWiki/FunnyMoments tries to invoke this trope]] by saying that nobody truly understands the beauty of her "Ionasal Bread." For the most part, it's just really terrible.

* CompleteMonster: The "[[EvilCounterpart other player]]", like the PlayerCharacter, has the power of Interdimend, the ability to visit and control a being from another dimension to interact with the world. Unlike the player character trying to save the world, this player's goal is to send Nero back to her world doing it in the most callous way possible. Controlling Prim, mind-child of Delta and Cass, they first assists [[DiscOneFinalBoss Zill]] in her plan of creating the Maternal Overseer, an soul absorbing atrocity, for her [[AssimilationPlot goal of making everyone's being into one consciousness]]. Once Zill becomes part of the Maternal Overseer, the other player uses it to help destroy the world while taunting Delta and Cass using their daughter as their avatar, with each plan stopped by the player's interference. Once everything was about to be solved, the other player makes their final move to eliminate everyone, transforming the Maternal Overseer into a giant mechanical dragon to convert every being into energy and using that energy to bring Nero back to their world "for 100% completion" from their side. When confronted about this not being a game, the other player shows they know but don't care. They'd kill thousands of residents of another universe just out of [[ForTheEvulz amusement]] and their own [[ItsAllAboutMe selfishness]]. It is also heavily implied that the other player was the one who almost killed Ion in her home world and forced her to send her soul to Ra Ciela.

* DeusExMachina: The pathway to Ion's true ending can come off as this, as Ion herself had already resigned her life to stay in Ra Ciela as the only known way back requires the sacrifices of many people. Said DeusExMachina lies in [[spoiler:Ayatane's "Reincarnation" recipe that allows the party to bring Prim's soul back to the living world, with next to no indication about such a function. And the real reason for Prim's prequisite for said ending was because the other Interdimend player had a way to return Ion and Nero (Ulyliyha) back to their original dimension that he doesn't bother to disclose, let alone attempted, as he assumed that the Soreil won't make it to the center of EXA_PICO. That said, players would be [[VideoGameCrueltyPotential heartless monsters]] if they take any of the other endings and decide to ignore the true one: Ion's original body dies in her world of origin, and there's the implications that her family would take it very hard, especially her little sister Aya, who personally witnessed the deadly attack that forced Ion to use the machine that took her soul to Ra Ciela. And the one who caused the attack in the first place was none than the player controlling Prim.]]

* StarCrossedLovers: Ion and Earthes could qualify as one if your relationship with her gets deep enough, due to the simple fact that she is from a different world than yours. It is possible for the player to marry her in this game (in Genometrics, at least) or ''Ciel Nosurge'' (the latter even have a marriage oath beyond the Seven Dimensions, courtesy of Nelico). [[spoiler:However, at the end of ''Ciel Nosurge'', Ion had to disconnect the Interdimend terminal to transfer it to Earthes avatar, possibly unable to reconnect to the same person again, or worse, ended up connecting to a player that doesn't appreciate Ion as much as the player from ''Ciel Nosurge'' does. The Ar Nosurge OS has a built-in interaction limiter for a reason.]]
** While it is possible for her to reconnect the terminal to the same player via the Sekai Link [[NoExportForYou in the Japanese version]], the Interdimend will be cut off again at the end of the game, separating you for good regardless whether she [[spoiler:stays in the reborn Ra Ciela or returns to Earth, as she lives in a [[AlternateUniverse different collective axis]] than the player's Earth]].
** This can be downplayed somewhat [[NoExportForYou in the Japanese version]] as you can get one of three possible voicemails from [[spoiler:Yuuki Nei]] after clearing both games, but unlocking the best of these voicemails requires [[spoiler:you to be marry her back in ''Ciel Nosurge'' in the first place.]]
