Married to his secret crush - Chapter 500: The End

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.

Only I know the end of this world.

One day our MC finds himself stuck in the world of his favorite webnovel. What does he do to survive? It is a world struck by catastrophe and danger all around.

His edge? He knows the plot of the story to end. Because he was the sole reader that stuck with it. Read his story to see how he survives!

Yun Ran, mercenary queen of the apocalyptic world unexpectedly transmigrated into the ugly, stupid second lady of the Prime Minister’s mansion with two little adorable three-year-old kids. Adorable baby 1 was a genius poison doctor who had a photographic memory and was “unremarkable”.Adorable baby 2 awakened the ultimate spiritual root that only appeared once every thousand years. When he pounds the ground with his small fist, the ground would shake. As for her, she had a spatial pocket with treasures in it. She contracted an ancient divine beast and refined peerless divine pills!***

Just as Yun Ran was gearing up to experience the joy of beating up scumbags…Can someone tell her why these few bigshots suddenly appeared before her?! The top tyrant: “I have a throne that you should inherit when you have the time.” The cold-blooded war god: “I think you have the talent to be a great general. Look at the millions of soldiers I have…” The best royal merchant: “Come, I’ll let you taste the joy of being the richest woman in the world.” Sinister state preceptor: “I’ll stab and curse whoever bullies you.” A certain ghost king traps her in his arms and snorts coldly, “Close the door and release the demons. No one should even think of coveting my treasure.” Yun Ran: “???”***

Rumor has it that the ghost king, Mo Beiyuan, has a pair of ghostly eyes. He was born under the destructive lone star, was bad towards women and was the most messed up character in all five countries. Yun Ran not only messed with him, but also wormed her way into his heart.#He was once a demon in the darkness, but he was willing to step out of the abyss of hell for her.#

Chang An is a sub-beast who, despite having the talent for the sword, did not have the constitution to support it. And his savior, Hua Yi, is a beastman on the run for his life.

This is a story about how two once innocent children had to grow up in such a cruel beastman world.
