Invaders of the Rokujyouma!?

Kiriha invites Koutarou to an amusement park that she had been to before. Sanae and the other trails the couple as they spot a rhinoceros beetle hero show. Ruth disappears and wacky highjinks ensue. Kirito and Koutarou get on a Ferris wheel, where Koutarou hears the true purpose of her invasion and the story of her first love, but then earth starts to rumble...

Yurika protected Harumi, but fell instead. Koutarou takes a sword from Harumi after a strange light engulfs her, but Maki disappears instead. Meanwhile, Theia and Kiriha can't get a hold of them, so they go searching for them. Yurika tells Koutarou about why she became a magical girl, and they decide to head back towards Apt 106. Maki, however, waits for them there...

Theia gives Koutarou special training for the Blue Knight role in the play. Someone unusual shows up to the stage, though... Then one day, there's a malfunction and Koutarou gets hurt protecting Theia. Clan appears and contests Theia over the thrown. There's a fierce battle between the two rivals, but there's another crisis brewing over Hercules, the beetle...

Sanae is caught by Ghost Hunters and almost sold to someone else.

The lot continue to fight over the room, and eventually decide to use the inter-club obstacle course marathon as their next battleground. Koutarou and Harumi enter as part of the Knitting Society, along with Sanae. Theia and Kiriha get their underlings and make their preparations.

With the help of his friend Kenji Matsudaira, Kōtarō Satomi moves in to room 106 at Corona House, attracted by the low, ¥5000 a month rent. The following day, while working at an archaeology site, he falls into a hole and meets a mysterious woman. He wakes up in the hospital and apparently just hit his head. At school, he joins the Knitting Club, whose only other member is Harumi Sakuraba, his upperclassman. His reason is to "do something for someone". When he comes back to his apartment, he finds Sanae Higashihongan, a ghost claiming that room 106 is her house and wanting him out but he keeps her at bay with sacred items from his grandma. They are interrupted in turn by Yurika Nijino, a magical girl who comes crashing through the window, Kiriha Kurano from underground, and Theiamillis Gre Fortorthe along with her servant, Ruthkhania Nye Pardomshiha who come out of the wall. Fighting ensues until the landlady, Shizuka Kasagi, comes in and forces them to sign a peace treaty.
