Mr. CEO, Your Wife is A Hidden BOSS! - Chapter 1242: Be Careful

When The Cute Kunoichis Spied on Their Teacher's Secret is a light novel written by Kazuma Kamachi and illustrated by Ryuushi Tajima.

The story takes place in a world where Japan never ended their isolationist phase, and agents from foreign powers are always threatening to steal the country's advanced technology. In order to combat this threat there has been a resurgence of ninjas that use Strategic Martial Arts, techniques that combine cutting-edge modern technology with a traditional foundation of martial arts and ninjutsu. The story follows Souha Sugiyado, a 17-year old ninja instructor and former ninja prodigy who was forced to retire from active duty by the wounds he suffered in his last mission. Souha's four students are all kunoichi who have all gained the rank of Elite Ninja, the highest official rank available to ninja. However, one day two Shogunate ninja approach him with the news that his four students have gone rogue and have stolen a portable modular nuclear reactor, and thus they ask for his help in bringing his students to justice.

When a Demonic Assault occurs, most people stuck inside of a Fracture end up hiding inside of a bunker in the hopes that they don’t end up killed by a demon.

Others might even hope for the slightest possible chance at signing a contract with a spirit and becoming a Guardian.

So when Scarlet was caught in a Fracture, the last thing she expected was to become a demon herself.

Exactly two centuries ago, humanity was struck with their very first Demonic Assault.

The skies above the capital of the US, shattering as if made of glass; demons of all kinds appearing out of nowhere; and no way to effectively stop them before the end of the Assault.

On the brink of devastation, some of the humans managed to find themselves offered a contract whilst inside of a Fracture. One bringing a chance at power, fame, and fortune.

Now, long after every nation of the world joined together to form the Terran Republic, Scarlet finds herself stuck trying to find a university from the Republic’s capital that will accept someone from a lower tier city into their midst.

But, as if that wasn’t already enough trouble for one person to bear, she somehow ends up stuck in one of the Fractures of a Demonic Assault while visiting her father figure’s company building.

However, she doesn't perish in the darkness and instead awakens her dormant bloodline as a noble demon.

A Blood Lycan.

Turns out she had been a demon all along and had been born for the apocalypse.

Suddenly a high school student Subaru Natsuki has been summoned to another world on the way back from the convenience store. With the biggest crisis of his life being summoned to another world and no sign of the one who summoned him things become worse when he is attacked.

She was an unprecedented assassin, a trump card deadly agent, but transmigrated through into Ye City’s number one prodigious good-for-nothing young miss.

I am an ugly woman? I will break out from my cocoon into a gorgeous butterfly that will blind your snobbish eyes!

I am useless piece of heap? Lightning in my hands, I will smite you to a well-cooked crisp!
