Meanwhile, he refuses to work, claiming it to be part of his training. Ichinose Suzuka from the neighboring sweets shop often takes care of him. One day, he picks up a strange, lizard-like being on the side of the road. At first, he planned to cook it, but Suzuka vetoes the idea. Instead, he names it "Haru" and keeps it as a pet. As he grows fonder of Haru, dragonkin suddenly invade from space! The dragons are about to take over earth, but Haru suddenly transforms from a lizard into a beautiful lady and persuades them! Wouldn't you know it -- Haru was actually the princess of the dragons! Mankind somehow avoids total subjugation, but now Haru joins the protagonist in his NEET lifestyle. Meanwhile, Suzuka is on pins and needles as they try to avoid the spotlight. Even now, dragons can be spotted here and there around town. Here begins their bizarre, yet down to earth daily life.

#3 It’s been a few weeks since Judgement Day — when dragons covered the world’s skies. Humankind has been trying to adapt to a new daily life. But far beyond the skies above, the situation in the sea of stars has grown intense. The dragons were split in half in their opinion on how to deal with humankind and in the confusion, Iris, dragon queen of the Sea and Water factions, descends to Earth, claiming the seas and barring all humans from entering them. With summer resorts and fishing shut down and even people in some countries, unable to travel outside their borders, things looked bleak. Days later, the dragon girl Dorami convinces Takeru, Haru and Suzuya to go to the beach for a vacation. What awaits Haru and the others as they approach the territory of the sea dragons? But for now, they’ll just have a barbecue. Maybe even split a watermelon.
#4 A few weeks have passed since the tumult of Iris, the Rainbow Dragon, leading her Sea Dragons to Earth to take over the world's oceans. The dragons' attitudes have softened since then. They no longer threaten to annihilate anyone who gets too close to the sea, for one. Humanity and dragonkind are beginning to adjust to a new world of coexistence, although for now many questions remain. This, however, is a complex matter on a global scale.
