Koutarou at last makes his return to Forthorthe, although it’s not in a very glorious fashion. Stranded on Planet Alaia with Theia and Yurika, he’ll have to figure out a way to use the limited resources they have to get past the imperial troops everywhere if he ever hopes to make it back to safety and the rest of their friends. Fate has a few familiar twists in store, however, as the coup d’état gets off to an ugly start and their enemies show their true colors.

Just starting high school, Koutarou is moving out on his own to take some of the burden off of his widower father. Lucky for him, he's found a room at Corona House. It has a great landlord, it's not too far from school, and best of all, it's dirt cheap. It really is perfect... except for the strange girls that keep appearing to try and take it over! But even as room 106 turns into a battlefield, Koutarou isn't willing to give up his apartment without a good fight. The invasion begins!

With the coup d’etat back home in Forthorthe finally reaching critical mass, Elfaria and Theia decide it’s time for them to return. Theia is reluctant to drag her friends into the politics of her homeland, but they’re just as stubborn as she is. They band together and set out for Forthorthe, but their enemies will make sure not even the trip there is easy. They all have a long, hard fight ahead of them—and this is just the beginning.

Kaito Sena's life hasn't exactly been easy. Unfortunately for him, death isn't about to get any better. Summoned by none other than Elisabeth Le Fanu, the "Torture Princess," Kaito has to choose what he wants for his second life-be her butler, or die a long, painful death by torture. What is he to do but become her servant...and help her eliminate the fourteen ranked demons wreaking havoc in the world! See the original light novel come to life in this gritty manga adaptation!

After the attack underground, Koutarou and company return to the surface to regroup and plan their next move. They know Ralgwin will continue to come after them as long as he still has a hold on Earth, leaving them little choice but to mount an offensive of their own in an attempt to put Vandarion’s coup to bed once and for all. Fortunately, they have a little extra help on their side with the arrival of Princess Nefilforan, known throughout all of Forthorthe for her military and martial might.

Koutarou and the others have at last defeated and captured Ralgwin, the leader of Vandarion’s faction. Given his importance to the rebellion and Fasta’s threats, however, Forthorthe is convinced it’s only a matter of time before his allies stage a jailbreak. They put everything on the line to keep him in custody. Even the court magicians and the princesses are getting involved, which complicates things for Grevanas. The old wizard grows desperate and finally decides to make his move. With neither side willing to back down, a grand battle lies ahead.

With the end of the year approaching, things are getting busy around Corona House. Even though it's winter vacation, there's a new play to get ready for, Koutarou has picked up a new part-time job that no one seems to know anything about, and Ruth has decided to take up martial arts training. Come January, preparations for "The Silver Princess and the Blue Knight, Part 2" kick into high gear, but when an old rival reappears dead set on revenge, Koutarou may be in for the trip of a lifetime.
