About

A fully animated and voiced sister life-sim with roguelite runs. Find a cure for Mio’s illness. Share meals and quiet nights at home, then enter the Abyss each day to fight, loot, and push deeper to protect your simple life together.

Storyline

Ten years ago, a mysterious giant labyrinth suddenly appeared on the surface of the world. It stretched endlessly into the depths, filled with ancient ruins and terrifying monsters. Adventurers from every land flocked to explore it, chasing fame and fortune in this new age of glory.

But for you, the labyrinth known as the “Abyss” is not just an adventure. It is your only hope.

Your beloved sister, Mio, suffers from a rare illness that no doctor can cure. The only clue to saving her lies somewhere deep within the Abyss. Every day, you descend alone into its dark dungeons, risking your life for her sake while she waits patiently at home.

As the days pass, the Abyss only grows more dangerous.

Will you find the cure before it is too late, or will the depths claim you first?
