Custodes of Elf Hearts is a lewd bishoujo tower defense game.

<Story>

The player is a half-human, half-elf protagonist who belongs to an underground organization at the lower levels of the World Tree, where the elves reside. Working from the shadows, he protects the peace of the underground slums beneath the great tree’s roots.

However, a traitor appears within the organization, causing a massive outbreak of black sludge-like creatures that begin to pollute and erode his home.

To resolve the incident, the protagonist receives a revelation from the goddess. Along the way, he must fight together with all kinds of elf girls and crush the ambitions of the mastermind behind the chaos.

With male elves suffering from declining fertility, the half-human protagonist seems to have become a target?!

Enjoy lighthearted and comedic daily-life stories, heart-racing CG events, and dynamic visual scenes.

<Tower Defense Battles>

Each character represents a turret, with their own unique stats and abilities.
During battle, players can spend resources to upgrade them and unleash powerful skills.

In addition, the goddess is not just there for show. She also possesses a goddess skill that can heal all allied units.

Of course, the enemy black sludge also comes in many different forms and possesses troublesome abilities. How you place your units and respond to each situation is entirely up to you!

<Lewd Elf Girls>

There are 6 elf girls in this game with whom the protagonist can develop a deeper relationship.

Each of them has a voluptuous body, a distinct personality, and her own unique fetish appeal. As the adventure and story progress, players will gradually get closer to their hearts and unlock more intimate, bolder adult events.

• Junior assassin in the organization

  ◇ Elena

The protagonist’s direct subordinate in the organization.

After being taken in by the protagonist in the past, she came to regard him as her master and holds a deep loyalty toward him.

She usually shows little emotion and is not good at expressing her feelings.

Toward anyone other than the protagonist, she is cold and difficult to approach. Because of this, the moments when she shows obedience, dependence, and possessiveness toward the protagonist reveal an even stronger gap in her charm.

• Owner of a brothel

  ◇ Lesia

A mature elf woman who runs a brothel.

By elven standards, she is no longer young, but her appearance remains beautiful and alluring, giving her a mature yet dangerous charm.

She is sharp, realistic, highly sensitive when it comes to money, and also enjoys conducting various experiments.

In particular, she has a strong interest in young human males. Using the methods of a mature older woman, she gradually tempts the protagonist, making her a carnivorous elf with a dangerous aura.

• Captain of the Princess’ Escort

  ◇ Alice

A noblewoman who serves as the captain of the Princess’ Escort.

She is arrogant and difficult to deal with, treating anyone she does not recognize with a haughty attitude, especially looking down on the weak.

However, beneath that domineering exterior lies an intense contrasting fetish.

In truth, she secretly desires to be humiliated and overpowered. When her proud self-esteem gradually crumbles, she reveals a lewd side completely different from her usual self.

• The seventh-generation princess to inherit the name “Elfe”

  ◇ Elfe Stamana

The seventh-generation princess to inherit the name “Elfe.”

She is cheerful, straightforward, and simple-minded, while also possessing excellent martial skills. She is an easygoing and approachable woman who does not sweat the small things.

Even as a princess, she is not overly modest or distant, and she can quickly get along with those around her.

Although she is simple, she is not oblivious. Beneath her bold and open personality, she also has a delicate side.

• Captured slave and modified human

  ◇ Mellie

A modified girl created through special technology.

She shows almost no obvious emotional fluctuation and rarely speaks on her own, which often gives her a cold and hard-to-understand impression.

However, that does not mean she has no thoughts of her own.

After joining the team, Mellie regards the protagonist as her leader and calls him “Master.” Though her reactions are subdued, her unwavering obedience and dependence create a uniquely sensual charm.

• The goddess of the world tree

  ◇ Elfe Anastasia

She is like a mother to everyone: easygoing, gentle, and carrying a slightly unpredictable playfulness.

Although she often gives off the impression of a silly big sister, she truly loves her children and places great importance on the promises she makes with others.

Tolerant, loving, and filled with the mysterious charm of a goddess, when she shows her playful side, she also reveals an irresistible mature allure.
