Heroines, Villainesses, and the Hero's Yandere Harem? I want them all! - Chapter 4: Basement

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.

Kanzaki Ryoma transmigrated into the world of Tokyo Ghoul and began fusing with Uchiha Madara. Determined to bring an end to this twisted world, he chose to implement the “Eye of the Moon Plan” and ultimately activated the Infinite Tsukuyomi!

Strength.... That's all that matters in the end.

After being abandoned by his own family, and shunned for having no mana in a world dominated by magic, ex-prince Arvell Relas Vispia was forced to live on the streets with whatever meagre money he had left.

However, fate had something else in store for Arvell.

After meeting the spirit inhabiting his amulet, Arvell gets reborn as a Nephilim.

A being that has the powers of a god.

Time, Space, Life, Death.

All submitted to the authority of a Nephilim.

Betrayed by those he once called family, Arvell swore to get revenge.

Revenge on all those that mocked him and shunned him as a 'failure.'

Revenge on those who betrayed him without a second thought.

This is a tale of how a young prince shunned by the world as a 'failure' rises and ascends to the pinnacle of strength.

A door unfolded before him.Evil thrived, and whispers spilled from within.The resentful compound eyes flickered and vanished, the presence longing to burst out was blocked inside, and the alluring murmurs echoed in the ear.The sticky, pink brain mumbled something. A figure cloaked in a yellow robe watched from a distance. A dark green presence, smelling of blood, roared. A string of wondrous soap bubbles released friendliness—and many, many guests.They sincerely invited Lu Li to join this mad party.Lu Li stepped in, his stride resolute and unwavering.He had no reason to refuse.
