* DrivenByALoveInterest: Maya is so obsessed with her little brother Asahi, that when he goes to another world after going through a coma, she follows him via bashing her head repeatedly on a wall.

** Maya becomes completely ruthless if Asahi's life was threatened.

* DeconstructedCharacterArchetype: Asahi serves as this for the StockLightNovelHero, specifically the stereotypical ''isekai'' protagonist, as a nerd with low self-esteem and poor fitness. Realistically speaking, someone like him wouldn't be in the least bit qualified for a job that requires hunting strong monsters on the regular--and he isn't. His physical stats are about as laughable as you'd expect from an out-of-shape {{otaku}}, he's a poor swordsman due to never having actually held a weapon in his life and he tends to get himself into hot water because he keeps expecting the world around him to [[RPGMechanicsVerse operate on video game mechanics]] when it only partially adheres to them. He also has no cheat skill nor is he overpowered, with his older sister Maya becoming the freakishly powerful one instead.

* BoobsOfSteel:
** Both Maya and Kilmaria (especially the latter) are well-endowed women who are the two most powerful beings in the fantasy world.
** Gloria, while not as overly-busty, still has a sizeable rack and is fully capable of eliminating threats with one-hit.

** Kilmaria nearly tries to intervene in a swordfight between Gloria and Asahi out of concern. She even incinerates a necromancer serving under another general of the maou when he insulted Asahi.

* TrappedInAnotherWorld: Starts the classic way, with the protagonist getting into an accident and reincarnating into a fantasy world after his apparent death. Then it takes a turn for the wacky when the protagonist's sister figures out what's going on and ''beats herself into a coma'' to follow him there.
