About Fiendish Quest

Fiendish Quest - about the game

To save his petrified mother, the protagonist embarks on a journey to find the legendary orbs said to grant any wish.

This journey is not only one of rescue but also one that unravels the mystery behind his mother's petrification,

and why the people of this world are so cruel.

Character

A half-demon, half-human girl.

Though she appears mature, she is still innocent and naĆÆve on the inside, with little awareness of the dangers around her.

To save her mother—who was turned to stone by a mysterious illness—

she musters the courage to go against her grandfather's wishes and leaves the village.

Her deep love and determination for her mother become the driving force behind her growth and adventure.
A young swordsman who trains hard with one goal: to protect his childhood friend, Tarna.

Though he cares deeply for her, his shyness causes him to act awkwardly, unable to express his feelings honestly.

While he does not travel with her, his heart is always with her.

Game System

ā–  Orbs Scattered Across the World

Exploration and treasure hunting are the core of the game.

The player must find all seven orbs hidden around the world in order to have their wish granted.

Clues to their locations can be obtained by consulting the fortune teller at the Adventurer’s Guild.

Some regions may be blocked by obstacles. In such cases,

you'll need to find specific "key items" to unlock the path and continue your adventure.

Clues about the orbs' locations can be obtained from a fortune teller at the Adventurers' Guild,

helping you take the next step in your quest.

ā–  Find the Right Weapon!

Choose weapons suited to the enemies you encounter.

With the right equipment, you'll be able to launch enemies away the moment they get close!

Having the appropriate weapons makes infiltrating enemy bases much easier.

On the other hand, entering without the correct weapons means you'll have to avoid all enemies.

Get hit too many times, and it's an instant GAME OVER.
