About This Game

Story

One of the naturally occurring phenomena, "Dungeons."
These places, whimsically created by gods who govern heaven and earth, have captured the hearts of many.
People eventually become adventurers, and a culture of challenging various dungeons developed.

One day, two adventurers challenge a newly born dungeon.
They are the protagonist (senpai) and a junior adventurer named Nao.

It is a dangerous and unknown dungeon from which the research team has withdrawn, and the leader, the doctor, was taken away by monsters.
Along the way, Nao is attacked by a monster and falls into a special abnormal state.
To treat Nao, the protagonist picks up a paper dropped by the abducted doctor.

What kind of ending will this adventure have?
