Dungeon Toilet (JP: Isekai no Toilet de Dai o Surunote ) is a fantasy seinen manga written and illustrated by Roots. It was serialized in Young Champion Retsu from 2018 to 2021. While it technically falls into the isekai genre where people are transported to another world and have great adventures, Dungeon Toilet has a somewhat more humble premise than most.
It's not about saving the new world, it's about pooping in the new world.
Our hero is Yotaro, an ordinary everyman who is Trapped in Another World — of the bog-standard Fantasy RPG variety, naturally — and is adjusting to his new life as an adventurer. His primary concern in life isn't about saving the world, hoarding its riches, or wooing its women. He just wants to find a clean place to take a crap, and some decent material to wipe his butt with. Everything else is purely a secondary concern.
This being primarily a comedy manga, of course, he rarely gets his wish.
The manga is licensed for North American release by Seven Seas Entertainment.
Dungeon Toilet contains examples of the following:
- Artistic License – Biology: While the manga does offer some real factoids about toilets and toileting, at times it doesn't let said facts get in the way of a joke. For example, in one chapter Yotaro is shown pooping out something that was all the way up in his stomach only moments before, which would be impossible under almost anything resembling normal circumstances.
- Calling Your Bathroom Breaks: Yotaro talks in detail about needing to go to the bathroom at least once a chapter. In fact, he rarely talks about anything else.
- Edutainment: The manga provides some factual information about various matters related to toilets and/or taking a dump, such as the use of the aloe vera plant for treating constipation. It's not necessarily vital or terribly useful information, but it's information nonetheless.
- Gag Series: Dungeon Toilet offers the occasional bit of educational content concerning toileting, but its main concern is comedy — largely of the Toilet Humor variety, naturally.
- Just Eat Gilligan: Yotaro's weird fixation on passing stool gets his party in trouble more often than not, sometimes to ridiculous extremes. It appears the only reason his companions haven't abandoned or killed him yet is that he very occasionally comes through for them. Of course, if they were to do that, the manga would effectively end — Yotaro and his butt are the primary sources of the manga's content.
- New Life in Another World Bonus: Rather atypically for the isekai genre, Yotaro hasn't gained any particular special ability or status since coming to the alternate universe. His only remarkable characteristic is his encyclopedic knowledge of toilets, that is — and that proves a liability far more often than an asset.
- Shout-Out: The first volume's cover rather boldly references the cover of Delicious in Dungeon's first volume.
- Spice Up the Subtitles: In a weird inversion, the translated title is less ribald than the original Japanese, which translates roughly to "Taking a Crap in a Fantasy World Toilet''.
- Third-Person Person: Gigi doesn't use first-person pronouns, and only refers to herself by name...but only in the first chapter. She drops the speech pattern in later chapters.
- Toilet Humor: Humor related to fecal matters is this manga's primary focus. While most of it tends to be more awkward and uncomfortable than outright disgusting, when the humor wants to get gross, it goes for it. In fact, the first chapter involves Yotaro wiping his butt with a slime creature, the creature crawling up his butt for a night, and then Yotaro shooting it out of his butt like a cannonball the next time he visits the loo.
- Trapped in Another World: Yotaro was transported from modern-day Japan to his current garden-variety fantasy world, though the details of how or why this happened have yet to be elaborated on.
- Unfazed Everyman: Despite being teleported to a fantasy world and adjusting to life as an adventurer, Yotaro seems to take everything mostly in stride. He worries more about running out of toilet paper than dying in battle.
