The Innkeeper - Chapter 1560 Ravenous maw of Hell

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.

Entering a clichéd female novel world by accident. As long as he changes the negative perceptions of four female protagonists towards men, he can return to the real world with a reward of one billion. At first, Ji Mu thought this was a way to get rich, but as time went by, he gradually realized that something was wrong.“System, didn’t you tell me that these female protagonists extremely despise men, and no matter how good I am to them, it would purely be a friendship?”As Ji Mu looked at the few female protagonists in front of him, their cheeks blushing, their eyes filled with pink hearts, and constantly closing in on him, he broke out in a cold sweat, shrinking into a corner and shaking.“I’m going to ask you one last time, are you really sure that this is just pure friendship?”[Host, forget about friendship, do you know what a juicer is?]Faced with the system’s sudden nonsensical question, he swallowed nervously, feeling an increasingly ominous premonition.“W-what do you mean?”[Just a friendly reminder…]The system paused, its tone filled with helplessness and despair.[All four of them are in front of you.]…If you were simultaneously pursued by beautiful girls with different personalities, what would you choose?Only children make choices; normal people know to turn around and run.“I can’t even handle one, let alone four!”Ji Mu desperately clung to the doorframe and struggled in desperation before being dragged into the room: “System, save me!!!”
