Van is a young man who regularly fights his way through the Wyrm Hole dungeon to meet up with its boss, a dragon named Ryuka who is actually his childhood friend. Ryuka can transform into a more humanoid form, in which she and Van hang out for his monthly visits. Although most of the subordinate monsters of the dungeon see Van as just an uncommonly skilled warrior, Ryuka's four highest-ranking lieutenants—a harpy, a minotaur, an orc and a wolfman—are aware of Van and Ryuka's long friendship and are eager to help it become something more romantic.

• Ryūka Obushidian • Ayane Sakura (voice comic) • Ryuka was saved by Van as a child and became fast friends with him. She does truly wish to win his heart, but Van is a bit too dense to understand her tsundere tendencies. • Ban Shiriusu • Yoshitsugu Matsuoka (voice comic) • Ryuka's childhood friend. He is the strongest class of adventurer due to getting "regular exercise" attacking Ryuka's subordinates on a monthly basis. He moved to the nearest village to get closer to Ryuka. • Harpy-san • Larissa Tago Takeda (voice comic) • A harpy and one of the dungeon's four administrators. She's constantly trying to get Van and Ryuka's relationship to progress to something sexual. For a while, she had herself confused with a siren and insisted she had a beautiful singing voice. • Mino-san • Yuto Ishida (voice comic) • A minotaur and one of the dungeon's four administrators. Despite his manliness, he's obsessed with pure relationships and becomes violently angry whenever the subject of cheating or promiscuity comes up. • Orc-kun • Hideyoshi Nozawa (voice comic) • An orc and one of the dungeon's four administrators. Even though he looks dumb, he's actually a genius tinkerer who often comes up with inventions that are either incredibly useful or completely useless. Sometimes they blow up, though. • Uru-kun • Shun Kamimoto (voice comic) • A kobold and one of the dungeon's four administrators. He's responsible for personnel placement, and despite looking wimpy, he can transform into a werewolf-like creature when he's in trouble.

Written and illustrated by Yasuhisa Kuma, Dungeon Friends Forever was initially published as a webcomic on the Nico Nico Seiga website on September 3, 2021.
