Kazuhiro and Marie decide to invite Wridra the Arkdragon to Japan to offer her some rest from her demanding job of raising children. Kazuhiro takes his two guests on a trip to the hot springs, where they all grow closer and promise to continue adventuring with one another even in the dream world. However, the time for them to challenge new labyrinths is approaching... Along with the elf, it's time to say, “Welcome to Japan, Ms. Arkdragon!”

Welcome to Kazuhiho's home! After earning the right to explore the ancient labyrinths, Kazuhiho and Marie depart for the raid on the labyrinth along with their powerful new ally, Wridra the Arkdragon. Meanwhile, in Japan, Kazuhiro prepares to invite Ms. Elf to Aomori, the home he grew up in and the place where his grandfather currently resides. Kazuhiho can hardly contain his excitement for the labyrinth, and Marie can hardly contain her excitement for the bullet trains. More adventure awaits in volume 3!

With the raid on the ancient labyrinth underway, Kazuhiho, Marie, and the others finally head for the third floor. The difficulty within the labyrinth ramps up as those from other countries interfere with the party’s progress, but they continue to have a blast on their adventure as usual.

During Kazuhiro and Marie’s travels between Japan and the dream world, the mansion they’ve been living in on the other side has become fully operational.

Kazuhiro and company successfully hold back Gedovar’s invasion and challenge the third floor master to destroy the ancient weapon their enemies are after. As the invaders seek the means to control monsters, Kazuhiro discovers an unexpected secret.
