Hitomi Tachibana is a young and spirited archaeologist. She holds a deep passion for

adventure and the hidden mysteries of the world. After completing her studies at Seito

University, Hitomi decides to embark on a journey around the world to uncover lost

treasures.

Her journey begins on a remote island in the Pacific Ocean. She hears rumors of a

legendary treasure believed to be buried within a deep and mysterious cave. The

archaeologist believes this is the perfect opportunity to prove her abilities and discover

something spectacular.

Armed with a map obtained from an antique collector, Hitomi sets out on a perilous

expedition into the cave known as the "Coral Secret". The cave is guarded by numerous

puzzles and traps that deter anyone daring enough to seek the treasure. However, Hitomi

remains undeterred. She has trained herself well, possesses profound archaeological

knowledge, and remarkable physical abilities.

Upon entering the dark cave, Hitomi realizes that not only will her intelligence and

physical strength be tested, but also her resilience and perseverance in the face of

unexpected obstacles. Complex riddles, endless mazes, and deadly traps await her at

every turn. Yet, she refuses to give up.

During her winding journey within the cave, Hitomi discovers signs that she is not alone.

There is a mysterious presence lurking in the shadows. She can sense that there are

others or supernatural entities interested in this treasure. Are they rivals also in search of

the treasure? Is there a supernatural power at play?

In her ongoing adventure, Hitomi must rely on her knowledge, intuition, and the assistance

of individuals she encounters along the way. As she draws closer to the coveted treasure,

deeper mysteries unfold. Hitomi realizes that this discovery may have far greater

consequences than she initially anticipated.
