* {{Moe}}: Pretty much Helen. Just take a look at her! And not only is she physically cute, but her curious, innocent, happy and kind personality make her extremely adorable and endearing.
* NightmareFuel: Even for a LighterAndSofter series, it still has some quite scary and disturbing moments. Some stories of volume 1 and the chapter "Helen and the Night Sky" come to mind.
* TearJerker: Most of the endings tend to be this, though most of them aren't really [[DownerEnding Downer Endings]].
