Become tentacle, destroy the town and humiliate girls!

The protagonist Nimura Kyouji, runs a hot spring inn at a hill station and lives a quiet life away from the city. But, Kyouji also has another motive. He secretly preys on the guests who stay at his inn and uploads their videos on the internet for a large amount of money.

Today, an innocent family from Tokyo arrives at his inn.

"Good afternoon, we made a reservation at this inn, the name is Hidaka――......"

This time, the Hidaka family, who owns a fashion company in Tokyo, will be staying at his inn. When there are a woman with big breasts and her high school girl daughters, there is literally no way that he would ignore this opportunity. Even with the husband and the daughter's childhood friend in his way, he knows that he will figure something out later.

Thus, Kyouji immediately carries out his plan to ruin the mother and daughters of the Hidaka family.

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?

Asougi City, on the Seto Inland Sea, is dominated by the corporation whose name it now shares.
The Asougi Group ordains every aspect of the citizens' lives, but as those everyday lives are peaceful, few people object or question it at all.

Only one thing disturbs the city's harmonic order: the activities of the "Anti-Aso" hunting clans, who snatch people off the streets by force and then hustle their bodies on those same streets to customers.

The Anti-Aso struggle, the suits plot their removal, and all the while the impending Founder's Birthday Ceremony accelerates tensions everywhere.
And the balance in the city begins to shift, grinding people to dust in its motion...

Live, die, live again.

A few people awoke in an unknown place.
All of them, strangers to each other, are supposed to be dead.

Amid their confusion, a mysterious entity offers to extend their life with a single, non-negotiable condition: they must eradicate various specters in this world. Only the resurrected, such as themselves, could perceive and eliminate these otherwise imperceptible apparitions.

Their revival, however, has its side effects; an abnormally strong libido, the persistent dread of an unpredictable call to battle, and the constant terror of their borrowed time running out.

Still followed by the clutches of death, their cruel daily existence was about to begin...

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?
