- Awesome Moments: When Hajime and company find out that Myu, the little mermaid girl, had been kidnapped by slavers, their response is to completely wipe the organization out and free everyone. No mercy is had for any of the perpetrators, and the lead slaver isn't even spared a Pre-Mortem One-Liner before being triple-tapped in the head by Hajime himself.
- Best Known for the Fanservice: The infamous Ass Shove scene with Hajime & Tio went viral on Youtube, garnering over a million views in a little over a month. It doesn't help that the scene in its entirety takes up almost a third of a whole episode.
- Catharsis Factor: There is a massive satisfaction to seeing Hajime and his team rescuing the Hero's Party. Especially with the latter group's complete disbelief that the "stranger" that completely eclipses them them all in power is the same boy that most of them bullied back on Earth.
- Complete Monster: Ehitorujue is the god who rules Tortus. Slowly growing bored and lonely due to his immortal life, Ehito develops a cruel and sadistic personality after seeing his people suffering. To that end, Ehito manipulated several races to fight brutal wars and has his worshippers commit countless atrocities. Attempting to manifest himself in Tortus, Ehito attempts to bodyjack a powerful Vampire Princess, Yue. When that failed, he then set his sights towards a highschool student who has a misguided sense of justice which resulted on him and his classmates being summoned into another world. After Yue was released from her seal, Ehit successfully possessed Yue while torturing her inside out. After being expelled from Yue's body, he absorbs all of his creations in order to finish the heroes once and for all. It was soon revealed that Ehit's master plan was to destroy Tortus and attempts to find a new sandbox to play with in other worlds solely to satiate his boredom.
- Funny Moments:
- The Ass Shove scene and its aftermath.
- Hajime's edgy attitude and snark is a good source of comedy in the show.
- Hilarious in Hindsight: Tia Ballard playing Yue in the English dub. Yue is a Really 700 Years Old vampire who can cast powerful magic. In another of Ballard's recent roles, she played Entoma in Overlord, who notedly fought that show's resident magic casting vampire. And this won't be the last time she falls in love with a character voiced by Matt Shipman.
- Jerkass Woobie: Eri might have been a disturbed Yandere, but after being raped by her stepdad and her mother beating her, to the point she tried to kill herself, it's hard to not feel sorry for her.
- Moral Event Horizon: Haiyama Daisuke was certainly a despicable and unlikable bully, but he really sinks low with his attempt on Hajime's life just so he can have Shirasaki all too himself. If that wasn't bad enough to cross it, then he definitely proved himself to irredeemably evil when he conspired with Nakamura Eri to betray his classmates and the kingdom to demons just so he can kill Shirasaki and have her reanimated as a doll to love only him. Unlike his murder attempt with Hajime, the entire class does find out about his treachery and rightfully lose all patience with him, and Hajime (who didn't bother killing Daisuke because he deemed him not worth the effort) finally loses all sense of mercy towards him the moment Daisuke stabs Shirasaki, outright killing him by leaving him to be devoured by monsters, mirroring Daisuke's murder attempt and what Hajime had to go through in the abyss.
- Suspiciously Similar Song: Tio Klarus's Image Song, "Dragon's High", sounds a lot like "Livin' La Vida Loca" by Ricky Martin.
- Values Dissonance: Hajime use of his makeshift Cool Guns can be seen as this. In Japan, gun control laws are very strict in upholding, where only the police and JSDF are authorized to use them. It's also very, very difficult for a law-abiding citizen to own a firearmnote , and a very big taboo to even hold one (especially if the one holding it is still a minor, since Children Are Innocent are at play in Japanese society). This serves as a metaphor on how badly Hajime's mental state has deteriorated in the Great Orcus Labyrinth.
