You are Ikki, a young boy living on a small island with his intrepid grandfather who taught him everything he knows. Together they built Bathys, a pocket submarine, using recyled material, flotsom and jetsom.

After a catastrophe with an unknown cause, our heros, Ikki and his grandfather are separated. All that is left is the incomplete logbook.

You'll descend miles below the surface, where the sun never shines, where terrible currents, monstrous creatures and terrifying pressure are an insurmountable barrier to your progress.

Where the ocean seems to have no bottom, a new world beneath the sea may hold the key to the survival of humanity…

You will discover a detailed water world brought to life with hand-drawn animated graphics and immersive sound design.
