- Acclaimed Flop: The 2017 reboot was not watched by many (probably due to it being a remake of the 1994 original, which was not released outside Japan and a few other countries). Those few who watched though sees it as one of 2017's best hidden gems, praising its light-hearted comedy and characters, in contrast to other anime airing nowadays.
- Anti-Climax Boss: Subverted with the giant, floating sphere which was thought to be Lord Giri that contains the dancing old man and a loincloth. A demon claims that the whole journey was just a product of Kukuri's imagination and that it was the journey that counts. It then immediately turns out that the giant sphere was actually a mirror that shows a Guru Guru user's deepest fears, and that the real Giri is hiding in the sphere's shadow.
- Broken Base: Fans can't seem to agree whether the original 1994 anime or the 2017 remake is better, with fans of the former criticizing the remake feeling rushed and cutting out some of scenes from the original, while fans of the latter criticizing the old version's slow pacing, with some of the gags dragging too long.
- Big-Lipped Alligator Moment: In episode 19, Raid is seen looking at a photo book of Kaya in disgust.
- Bizarro Episode: Episode 20 of the 2017 series has a more serious and melancholic tone to it. The backgrounds also look noticeably more detailed and the color palette feels more washed-out than usual.
- Ear Worm:
- Fanon Discontinuity: Some fans ignore the existence of the sequel of the original anime, Doki Doki Densetsu, claiming that it doesn't have the charm and wit of the original series.
- Moe: Kukuri and Juju
- Older Than They Think: One of the older examples of Role-Playing Game Verse.
- Spiritual Adaptation: Barring the lack of iconic monsters, such as Slimes, and art of Akira Toriyama, this series is pretty much a more comedic adaptation of Dragon Quest.
- Squick: Old Man North-North rapidly shaping rice balls with his armpits.
- What Do You Mean, It's for Kids?: Played straight with the original manga and first two series, while inverted with the remake. The original manga ran on a Shounen magazine, with the original adaptation being targeted for kids, while the remake airs at Otaku O'Clock. Regardless, the show may look innocent with its cute art style, but it also have some more questionable moments, like names of character involving male organs (Barckweiner and Goedicke), and a scene where a demon used a spell to make Kukuri act seductively behind a paralyzed Nike as torture, with Kukuri even nearly stripping, especially in the remake. Keep in mind that she is only 13.
- Woolseyism: The Crunchyroll translation of the 2017 series changes some of the places and characters' names into puns reminiscent of later Dragon Quest games, such as Jemina Village to Boering Village, Koudai to Ainshent, and Wanchin to Barckweiner.
