* AlternateCharacterInterpretation: Bai Hua [[spoiler: can be seen as tool of Huai Te or someone who knows what is going on behind the scenes, and thus killed Ah-Xuan to spare him a possible life of misery or save the world from the conflicts his existence might cause. Furthermore one can see her as AntiVillain, WellIntentionedExtremist or AffablyEvil.]]
* AngstWhatAngst: Liu has no parents[[spoiler: Li Qiao En is her father/instructor]], almost everyone she got attached to was mentioned to have died and she herself has become dependent on drugs to prolong her short life. She is calm, cool and collected most of the time and also downright adorable in other and overlapping moments. [[JustifiedTrope Then again, she spent all her life in the military.]] It's just life to her.
* AwesomeMusic: The animated adaptation has some pretty great music going for it, most notably the [[https://www.youtube.com/watch?v=iw5r20Uo-ZA ending theme]] "Pray" by Lunar. The Japanese version of the [[https://www.youtube.com/watch?v=K1I8WiWkQvk opening theme]] "The Lost Eden" is sung by [[https://en.wikipedia.org/wiki/Alan_Dawa_Dolma Alan Dawa Dolma]], a Tibetan singer active in the Japanese music industry.
* {{Moe}}: Liu Li, Xiao Jiang
* NightmareFuel: The way Bai Hua [[http://www.mangafox.com/manga/school_shock/v01/c007.1/16.html looks]] is quite unsettling and doesn't fit the situation at all.
** And she doesn't do it just once.
** Also, she is apparently suffering from short term face-half loss. Spooky...
* {{Squick}}: Huai Te. He is quite possibly completely off his rocker, has wire constructs keeping his lids open at all times and his hair is pretty greasy, too. Moreover seems to be an {{Ephebophile}}. His character is probably meant to be repulsive.
