History VideoGame / Echocalypse

* BerserkButton: Katch will come after your hide if you scribble or intend to scribble on the books she guards.
* BigBrotherInstinct: Or big sister instinct if the protagonist is female. Regardless of gender, the protagonist makes good points in ensuring their little sister Rayna is safe and when she gets sealed in crystal, they seek to find the means that will set her free.

* {{Bookworm}}: Raven uses books to satisfy her minimal desire to communicate with others, spending hours of her off time just reading in the Forbidden City Library, which made her a close friend of Katch, the library's librarian and security guard.
* BuxomBeautyStandard: A handful of female characters have been shown to be busty, but Lindell stands out as one of the bustiest among them with an ankle-length dress with details provided to exemplify her arms and breasts which are adorned with diamond-shaped marks to put more emphasis on the titillation and having a beautiful face and long wide hair tied into a ponytail.

* CovertPervert: The official figure of Levia's "Striking Grace" skin reveals that [[spoiler:her nipples are pierced (the figure has a cast-off top)]].
* CrystalPrison: During the first confrontation with Wadjet shown, Rayna ends up getting sealed in red crystal.
* DamselInDistress: The game's plot is the Awakener's journey to free their younger sister Rayna from her Echo Crystal prison.
* DCupDistress: Snezhana uses her giant rack as an excuse for why she should be allowed to sit and rest on a conveniently placed stone bench... only to fall backwards on sitting on it, and revealing a secret room.

* HiddenBuxom:
** The female Awakener's Nebu outfit shows that she is more stacked than her default outfit makes her appear.
** Nanook looks modestly endowed in her normal attire as well. But is shown to have massive breasts when dressing in a swimming leotard.

* HotLibrarian: Katch, the person placed in charge of the Forbidden City's Library, wears a dress consisting of a short skirt that bares her arms and the underside of her massive breasts.

* JerkWithAHeartOfGold: Katch is quite extreme when it comes to protecting the secrets of her nation, but she can be encouraging of the protagonist in becoming Raeon's equal and potentially holds a crush on them. She also valued Raven as a close friend of hers.
* LettingHerHairDown: While Sova has most of her hair tied into a braid in her default design, she lets most of it lose in her swimwear attire.

* MrFanservice: The male protagonist can don an Egyptian-based attire that, while having him still wear pants, reveals more skin than his default attire.
* MyEyesAreUpHere: Sova complains about [[TheOneGuy Nevka]], the one guaranteed guy to interact with your party, complete with his own sprite, looking at her breasts instead of her face when speaking to her.

* NotQuiteDead: Rayna did not die in her older sibling's first encounter with Wadjet, she was still alive within the red crystals. To set her free, the protagonist will need to find a relic that will do the trick.

* PervertRevengeMode: Snezhana is at least nice enough to warn Nevka about invading her personal space again, shortly before he does so, but when he inevitably gets too close again, she smacks him in the face.

* RankUp: When the Nova Squad is sent to Nebu to investigate an apparent clue towards the Relic Component, Fenriru tells the Awakener that they'll become Nova's new captain if they find a lead, which comes to pass in Chapter 50. [[GameplayAndStoryIntegration This also marks the point where the Awakener's rarity becomes SSR.]] [[spoiler:It was actually Sova's idea, to instill a sense of teamwork in them so that they don't try to act alone like she once did before she joined Teslovik.]]

* ScaryLibrarian: Katch is a terrifying librarian. She once pursued a patron who took a magazine from the Forbidden City's Library, of which there were thousands of copies elsewhere, all the way to the Empire, on the other side of the continent, killed them, and took the magazine back. She also routinely cuts to ribbons anyone who tries to find the secrets in the library.

* SkewedPriorities: Snezhana, when searching for the relic in Nebu, constantly complains about how this is going to ruin her skin, how she wants a shower, and how exhausted she is, even as the others point out that they need that relic, lest the world come to an end.

* TheOneGuy: The male protagonist is the sole male member of the main cast who otherwise consists of females.

* UndyingLoyalty: Katch is loyal enough to Lady Raeon that she will not let he secrets out. But insists that she was pleading to the protagonist not to weasel his way into them. She even voices her gratitude for Raeon for renovating the archives. She even extends her loyalty to the rest of her nation, calling the spies she killed "filthy miscreants" as she collects their stuff as trophies.

* WouldHitAGirl: Since this involves many warzones where girls can attack him at any time, the male Awakener will not hesitate to fight back against his aggressors.

* BarelyThereSwimwear: Snezhana dons a fabric thin bikini that shows off a great portion of her ample breasts.

* JerkWithAHeartOfGold: Katch is quite extreme when it comes to protecting the secrets of her nation, but she can be encouraging of the protagonist in becoming Raeon's equal and potentially holds a crush on them.

** Nue wears a revealing qipao that reveals her cleavage down to above her navel, the side of her left breast, shows the left side of her torso with only some strings holding it, and there being no sleeve beneath her right shoulder.

** You can also find a picture of a robot sinking into molten metal, and [[Film/{{Terminator 2}} giving a thumbs up]].

* CleavageWindow: A handful of the girls wear attires that possess an opening that shows off each one's cleavage such includes Shiyu, Nightingale, Vivi, Iori, ect. The female can also wear an outfit to show off the cleavage of her ample breasts.

* MyEyesAreUpHere: Sova complains about Nevka looking at her breasts instead of her face when speaking to her.

* SkewedPriorities: Snezhana, when searching for the relic in Nebu, constantly complains about how this is going to ruin her skin, how she wants a shower, and how exhausted she is, even as the others point out that they need that relic.
