In the first volume of Tower Dungeon, super-strong farmboy Yuva got conscripted into the royal army to rescue the princess, who's been kidnapped by a necromancer and taken to the mountainous Dragon Tower. Yuva helped defeat a slime monster and recovered a gem that the necromancer says he's willing to trade for the princess. Then many of the royal guards were recalled to the capital, leaving Yuva with a straitlaced master archer and a bratty woman who knows fire magic.
Now in volume 2, the trio continues to explore for a safe (-ish) route up to level 100 where they can trade for the princess. Enriquo the archer leads them very cautiously. With their familiar staircase now guarded by giant suits of armor, he insists they map a new route. We learn that the dungeon is circular and 3 kilometers in diameter, which must make it like 15 or 18 km tall, given its proportions. Each level has numbered support pillars and is exactly 10 meters tall, though it seems that the very regularized main structure also holds more irregular and less well-built secondary features, perhaps later additions by less-skilled builders than the originals.
The trio gets lost in some repetitive, identical looking sections, then comes close to dying of thirst. Their equipment is stolen while they're sleeping, but when they give chase, they learn that the primordial human dungeon dwellers only wanted their salt (a precaution against another slime monster) for cooking. Yuva and his friends get back the rest of their stuff, plus some treasure, and the location of a water source and a secret staircase.
Back outside the fort, a boom town has sprung up to supply the soldiers going in. Besides Yuva's group, we meet a team of badass women adventurers who look like a roller derby team and all carry hammers, and a cat woman who wears a suit of armor. Fire mage Lilicen is eager to go back in the dungeon to beat out the new competitors. Yuva's sister has arrived from the village to work at the inn. She gets attacked by a 10 foot tall nobleman who can turn into a dragon, but the cat-lady knight protects her. Apparently everyone in the royal family is like 10 feet tall and a 'dracomorph', presumably including the princess.
Nihei seems to be drawing on tropes from both Dungeons & Dragons and dungeon crawling computer games like Rogue. The appearance of the stair guardians feels like a classic dungeon restocking procedure, and confusing architecture that trips you up as you make your own map is a staple of megadungeons as a genre. The sheer size of the place, and the identical superstructure of each level, is more like a video game though. Lilicen also shows Yuva you can break clay jars to find minor treasures, which is straight out of the Zelda games.
Yuva is our viewpoint character. He's from a small village and knows little of the outside world, so he needs Enriquo and Lilicen to explain how dungeons work to him. Along with us, he goggles at the noble cat woman and at the news that the kingdom's royalty are all giant shapeshifters. Yuva is kindhearted, which is why he talked to the salt thieves instead of fighting them. So far, his incredible strength has only been used for carrying heavy packs and breaking through a weakened wall into a secret passageway, but presumably he'll eventually use it for fighting, too. Yuva treats Enriquo like a boss and Lilicen like a sister, much to her annoyance.
The world Nihei is building here seems rough, crude, and brutal in a way that matches the style of his linework. The monsters are dangerous and strange in a way that borders on horror. The royal family is monstrous and inhuman, and at least one member is a Bluebeard-type who wants to cannibalize Yuva's actual little sister to prolong his life. Enriquo got a bladder infection when they ran out of water. The details add up to a world that's harsh and uncaring, where only people of incredible skill can survive.
