* HoYay: Toy and Halo.
* TearJerker, a number of them:
** Halo and Toy have both signed up for the army and are fighting a war in a remote region of a remote planet. Their unit gets ambushed on their first real sortie and all the soldiers except Toy and Halo are killed. Toy is injured, so Halo helps her limp along, and eventually fashions a stretcher so she can drag Toy to their HQ, keeping a determinedly positive attitude all the while despite the grim circumstances. [[spoiler:And then she arrives and tells the medic to attend to Toy, and the medic takes one look at Toy and says "How long has she been dead?" Halo's answer: a quietly stunned "''What?''"]]
*** This one was almost certainly pinched from ''Literature/AllQuietOnTheWesternFront''. Steal from the best!
** Glyph. No-one being able to remember it's existence even after it died to save Halo's life.
** Who can forget the scene where [[spoiler: Life Sentence kills herself]]. What makes this more heartbreaking is that [[spoiler: she tells Halo that with the war over, she felt her life held no more meaning.]]
** The ending is even worse. [[spoiler: After killing Luiz Cannibal and hijacking his ship, and with nowhere left to go but forward, Halo flies toward an uncertain future. Leaving her youth and past behind.]] Either a downer or bittersweet ending, but that depends on you.
