Io [Christmas Eve]

When campus nobody Seiji is attacked by unhinged space demons, it’s his classroom crush Yuuri who shows up to save the day! Her magical-girl powers easily vanquish the enemy, but a surprise ambush forces her to dive in harm’s way to shield him—leaving both fatally wounded. Luckily, Miss Fujiko arrives on the scene with an enchanted thread to bind both their life forces, saving them from certain death.

Over the next three months as Seiji and Yuuri slowly recover, the pair are on doctor’s orders to stay within one meter of each other or risk snapping their “red string of fate.” This means shacking up together and pretending to be a couple to avoid their classmates’ suspicions, but despite the clueless Yuuri claiming to be a “one-woman fortress with zero openings,” her natural powers of seduction quickly result in awkward situations that test poor Seiji’s sanity and self-control...

With his dream girl only centimeters away at every waking moment, will Seiji finally summon the courage to shoot his shot?

Sakashita Mina finds herself in a new town attending a famous all-girls high school. A misfit among a class of young, affluent ladies, she soon stops attending, realizing she'll never make any friends. In the year since, she has barely left her room.

Time passes slowly, each day a suffocating eternity. Mina would stare at the dried flowers in her room, trying to convince herself that this space is the only place in the world where she belongs.

Seino Ran is a child of a wealthy family and has lived the life her parents laid out for her. That is, until she realizes that nobody truly cares about her. With that in mind, her happy life begins to fall apart.

These circumstances lead both girls to apply for a live-in job at a seaside lodge. Here they meet, and the two girls end up spending the summer together and healing their wounded hearts. They found someone they could trust in each other, something they never thought they'd find again.

Spending her days together with Ran and the owners of the lodge, Yanase Michiko and Naruse Himari, Mina starts to wish that she could remain there forever. However, Ran's friend, Tachibana Sanami, gives Mina a reality check—it's high time she faces her problems.

Mina is convinced that nobody likes her. She avoids speaking her mind, she avoids school, and she avoids everyone she once considered friends. And while facing those problem will be tough, she also doesn't want to go back to that room and go back to being her old self.

As the time they have left at the lodge dwindles, Mina desperately searches for a place where she can belong. As for Ran...

Kyoichi Akikawa lost his family in a devastating plane crash when he was just a child.

"Will it really come someday?"
"Will the day ever come when I can truly move on from this pain?"

Kyoichi's stepsister Shizuku Akikawa has supported him all this time, while Yukitsuki Asaka bears a striking resemblance to Kyoichi's beloved older sister from before the tragedy.

As the paths of these three fated individuals converge, a mechanical god appears...

This is a story that heads towards the future.

Average joe Seiji encounters another magical-girl wonderkid—this time in the form of the mysterious Maja Krienke at his neighborhood park! Intrigued by her aloof charm and possible hidden motive, he tries to say something, when a Majin appears out of nowhere to reveal Maja’s true identity—a ruthless warrioress in cahoots with evil in exchange for the darker arts...

Stunned, Seiji agrees to serve as Maja’s familiar—or “satellite”—to aid them in taking down another, rival Majin’s demon hordes. He also stands to gain an impressive array of powers, but as a trade-off, he is now tightly bound to Maja by a magical tether, connecting him to her around the clock! As fate would have it, this rope is essential for Seiji to receive a steady supply of magical force—or risk his new satellite body collapsing in the mortal realm.

Forced into cohabitation with the lovely Maja effective immediately, he soon learns of her “unique” blindspots—for better or worse, her guard stays perpetually down around our loyal but increasingly frustrated hero, resulting in plenty of questionable close calls and near-accidents... Will an unlikely summer shack-up stir up something else between them, or will Seiji forever remain her indentured servant?

Japan has entered a new era, but Seiji’s life still remained the same. The only recent change has been Maja’s transfer to his class last winter.

However, one night he was attacked and had his life force drained by his underclassman Kanoko. She was actually a magic girl who protects people from monsters, but then why did she attack him? Did it have something to do with her family being attacked by monsters in the past?

It was decided by the magic girl society that Kanoko will stay together with him while they determine the cause of the unnatural changes to her body. Normally she is quite calm and collected, but living with her opened his eyes to another side of her. What will become of their time together full of unexpected intimate incidents?
