It turns out the timid, polite Harumi has a secret admiration for the way Kiriha teases Koutarou, so she does the unthinkable—she asks Kiriha to teach her how to become a bad girl too! In the next story, Clan also asks for something a little unusual. She starts martial arts training under Koutarou and Shizuka, but is she really up to the task when she can barely handle her own feelings? Next, there’s a surprise royal visitor to room 106, and Sanae, Yurika, and Maki decide it’s time for a makeover of magical proportions. Finally, it’s time for the Kisshouharukaze school field trip, complete with surprise confession!

With one of their own in trouble, Koutarou and the others are left reeling. Clan thinks she may have gotten to the bottom of things, but if what she says is true, the crisis they now face has been in the making for thousands of years. But the surprises are far from over there. A strange message for Koutarou could mean a tentative new alliance with a most unexpected partner. The offer comes at a time when they could desperately use the help, but what will the true cost be?

Summer vacation is right around the corner, but can Koutarou and the invaders manage a ceasefire long enough to actually enjoy it? Luck seems to be on their side when Ruth wins them a trip to a seaside hot spring, but it's not all fun and games with shadowy figures stalking their every move. When push comes to shove, can rivals become allies to save one of their own? Or is it every invader for themselves?

In this collection of side stories: Kiriha and Elfaria go toe-to-toe to decide who gets to take care of Koutarou when he gets sick on vacation, the story of how Yurika’s magical training went when she and Nana first met, and a chance date with Maki and Kiriha in a rather meaningful place. Then, in a very special feature, we get a glimpse into what life would be like between Clan and Koutarou if they started dating.

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.

The evil magical girls are finally making their move to seize the mana pool in room 106, just like Yurika's been saying all along! Koutarou crosses paths with an old enemy, and Maki is forced to decide whether she follows her duty or her heart.

Things have finally quieted down for Koutarou and the Corona House crew, meaning it’s time to kick back and have a little summer fun! Things start off at the beach where swimming, volleyball, and a test of courage are all on the menu. After that, there’s still plenty more fun to be had at a local festival and the amusement park. But when summer vacation draws to a close, Yurika’s worst nightmares come true... And what’s this about a surprise visitor at the apartment?

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.

While the magical girls of the Corona House crew are out on patrol one evening, they’re treated to a most unusual sight—a Sanae they don’t know falling from the sky! Just who is this third Sanae, and what is her story? Koutarou and the girls have kept Earth, Forthorthe, and Folsaria safe thus far by driving back evil after evil... But the threat lurking in the shadows now is unlike anything they’ve ever faced before. Will they still be able to defend themselves and everything they hold dear when the stakes of the battle they’ve been fighting shift significantly?

With Forthorthe on the verge of erupting into civil war like it hasn’t seen for thousands of years, Elfaria and the others do what they can to regain the trust of the citizens. But as it turns out, all of Forthorthe has their eyes on her, her daughter... and the mysterious knight in blue armor. Can they win the hearts of the people while trying to keep a very big secret from them? And with the vicious Vandarion plotting against them, it looks their bloodiest battle yet may be looming on the horizon.
