** Adam is absolutely this, having already charmed several female characters almost immediately after meeting them.
** Turned up even further when later Oska's older brother takes a liking to him, despite his insistence that it's "not like that".
** The Committee chairman, Eve, is this and a dude magnet due to her temptation ability.

* FantasticRacism: Most of the humans seen, though a few do change their tune.
* AGlassOfChianti: When the committee chairman is revealed, even though the heroes don't meet her yet, Adam correctly guesses from her tone she's holding one.

** Though later chapters imply that disaster should happen if monsters band together and that they are trying to prevent it. Still these hunters are portrayed as sadists and seem to take pleasure in trying to kill them.

* HidingInPlainSight: Eve has a chapter devoted to her trying to find the embodiment of light, the same way Adam found darkness as his shadow. Although she eventually gets over it, it's revealed two chapters later that [[spoiler:light was in her hair all along, and without it her hair apparently turns [[YouGottaHaveBlueHair green]].]]

* ChickMagnet: Adam is absolutely this, having already charmed several female characters almost immediately after meeting them.

* TalkingAnimal: Hachi, who is a talking dog.

* WorldTree: One of these is shown at the base for the World's Strongest committee that connects to Hell. It's later revealed by Lucifer that this tree grows by eating souls (the older the souls, the more it grows), and his plan was to get it to grow large enough to bring demons to the surface and take over the world.
** Ends up becoming even more important later. [[spoiler:It turns out the world tree goes through a cycle of harvesting enough souls to reach heaven and bear fruit, along with wiping out all remaining life on the planet. The fruit bears new species to dominate the world, and the Wisdom Emperor, Adam, and Eve are all part of the newest species.]]

''Choujin Gakuen'' provides the following tropes:

Meet Adam Shinjou, a very nice and insightful kid who just happens to attract supernatural occurences. Wherever he goes something bad tends to happen to things around him- so much so that he's been forced to travel on his own. One day while seeking shelter from a storm in a supposedly abandoned mansion, he meets a little demon girl name Oska L Duke who has been stuck in the house for years. The two quickly becomes friends and, after an incident involving monster hunting nuns, decide that if the world won't accept them, they'll make a school for the supernatural kinds.

* AGlassOfChianti: When the committee chairman is revealed, even though the heroes don't meet her yet, Adam correctly guesses from her tone she's holding one.

* {{Artifact of Doom}}: The aptly named Living Artifact of Mass Destruction.

* SpoiledBrat: The Chairman.
