◆Helena Rubinstein

Born into the prestigious Rubinstein family, Helena is blessed with exceptional magical talent and serves as the class representative at the academy.

Has been close to Louis for a long time, doting on him for years, and everyone expected the two of them to marry someday.

However, the moment she discovers that Louis possesses no magical power, her attitude changes completely...!

Despite her confident personality, Helena eventually falls to one of Louis's most terrifying alchemical techniques:

Semen Extraction.

This forbidden alchemy inflicts an overwhelming heat if they go too long without absorbing semen into their body.

Desperate to have the curse lifted, Helena reluctantly agrees to accompany Louis on his journey... even if it means placing herself in the hands of the very person she now despises.

◆Cecilia Feliciano

A timid woman.

Shy, clumsy, and easily flustered, Cecilia struggles to fit in and often spends her lunch breaks alone in the courtyard.

One day, through a stroke of terrible luck, she falls to one of Louis's forbidden alchemical techniques...

Exhibitionism.

This alchemical curse causes to become intensely aroused whenever their skin is exposed.

If too much time passes without exposing herself, the curse overwhelms her with irresistible desire.

To keep the curse under control, Cecilia is forced to secretly indulge in acts of exhibitionism throughout the academy...

◆Charlotte Rosalie

A woman in the same class as Louis.

Popular among her classmates, Charlotte is admired by everyone and has always seemed far out of Louis's reach.

A diligent student, she devotes herself to studying magic every day. However, despite all her hard work, she has never been particularly gifted at it. Having admired magic for a long time, this has become a source of deep insecurity for her.

Even someone as admired as Charlotte eventually falls to one of Louis's forbidden alchemical techniques.

Through a carefully devised scheme, Louis places Charlotte under the effects of Replication.

With this alchemy, Louis gains the ability to create and manipulate replicas of Charlotte's most intimate parts whenever he wishes...

Louis can't help but wonder why she's so devoted to him...

However, while talking with his longtime friend Helena, he uncovers a shocking truth.

It turns out that Solegna has also fallen to one of Louis's forbidden alchemical techniques...

◆Sister Lucia

A kind-hearted sister who serves in the Chamber of Prayer, where students offer their prayers to the gods.

Whenever Louis and his companions return exhausted from their adventures, she gently restores them to full health.

One day, after Louis confesses the many sins he has committed before her, tentacles summoned through his alchemy suddenly wrap themselves beneath her habit...

Transforming into a Tentacle Armor that can never be removed.

The living armor remains entwined around Sister Lucia's body forever, constantly caressing her from within... ♡

◆Nudia

A mischievous fairy who is always completely naked.

She teaches Louis the secrets of alchemy, but she's incredibly forgetful and has absolutely no filter.

Nudia asks Louis to destroy the magical seals hidden throughout the dungeon known as Arcana, where the forbidden power of alchemy has long been sealed away.

◆Louis Grayburn

The protagonist of the story.

Born into the prestigious Grayburn family, Louis enrolls in the First Royal Imperial Academy of Magic in Nocturne, only to discover that he possesses no magical power whatsoever, making him the academy's laughingstock.

However, a fateful encounter with the forbidden art of Alchemy completely changes his destiny.

Armed with his newfound power, Louis subjugates the heroines, freely using alchemy to bend them to his will and satisfy his every desire.

Like any man, he has a strong fascination with all things erotic.
