<Story>

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.

<Tower Defense Battles>

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

A direct junior subordinate of the protagonist within the organization.

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

She is usually rather emotionless and not very good at expressing her feelings. Toward anyone other than the protagonist, she remains cold and difficult to approach. 

• Owner of a brothel

  ◇ Lesia

A mature elven woman who runs a brothel.

By elven age standards, she is already considered an older unmarried woman, yet her appearance remains beautiful and alluring.

She worships money and lust in equal measure, greedy for wealth and ravenous for sex. She especially favors young human men, while also being deeply passionate about all kinds of experiments. 

• Captain of the Princess’ Escort

  ◇ Alice

A noblewoman who serves as the captain of the princess’s guard.

Proud and difficult to deal with, she acts arrogantly toward those she does not acknowledge, and looks down on the weak in particular.

However, beneath her domineering exterior lies a strong and unexpected hidden kink. 

• 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 visible emotional changes and rarely speaks on her own, often giving others the impression that she is cold and difficult to understand.

However, that does not mean she has no thoughts of her own. After joining the party, Mary comes to see the protagonist as her leader and calls him her master. 

• The goddess of the world tree, first queen of Elfland

  ◇ Elfe Anastasia

The first queen of Elfland.

Considered to be everyone’s mother, she is easygoing, gentle, and occasionally playful in a way that makes her hard to read.

Although she often gives off a silly big sister vibe, she truly loves her children and deeply values the promises she makes with others.
