■Story
From the city beneath the waves—a journey across time and space.

The protagonist, a modern-day university student,
is hit by an unprecedented storm while on a voyage to Dan-no-ura.
He looks up and sees the sky swarming with countless monsters.

An elegant man in a kimono protects the protagonist from the monsters.
"I, Kiyomori, swear by the name of the Heike clan and will guide the princess."
He picks up the protagonist and leaps into the sea.

Their destination is Ryugu, the water city ruled by the dragon god.
Chosen by the Dragon God as a "Divine Child," the protagonist embarks on a journey to save time and space with the "Eight Leaves," heroes who have carved their name into history.

■ Living Together and Forging Bonds in "Ryugu"
The game's base is the mystical water city of "Ryugu."
As the protagonist lives alongside the Eight Leaves, they enjoy everyday interactions, including conversations that change with the time and season.
The "Story of Ryuugu" unfolds as the Eight Leaves, summoned from different eras, face conflicts as companions and deepen their bonds.

■ Travel Together to Know Him Deeper in the "Historical World"
The Eight Leaves he meets in Ryuugu allow the two of them to travel together to the eras in which he lived, including the Heian, Sengoku, and late Edo periods.
In each character's "Otherworldly Story," they battle mad gods connected to each of the Eight Leaves, depicting the profound drama unique to historical fiction and the bonds that grow through their shared struggles.
Whether you deepen your relationship and become lovers, or forge friendships as allies, you can enjoy the story that suits your style.

■ Defeat your enemies with the secret technique "God Induction"
Battles involve placing cards in the front and back lines while considering elemental compatibility.
You can easily enjoy them with the auto-organization, auto-battle, and skip functions.
"God Induction," which summons a god connected to the Eight Leaves, is a powerful special move that is both visually stunning and visually stunning.

■ Feel a deep love close enough to touch
"Divine Energy Infusion" allows you to enjoy sweet physical contact with the Eight Leaves using touch actions.
"Sleeping Together" lets you fall asleep next to him, allowing you to hear his breathing and talking in his sleep, and he will respond to your pokes.
Even on busy days, you can easily interact with him and experience the thrill of his presence.

■ Feel him even when you can't see him
In addition to accumulating training items over time, the Eight Leaves will complete various requests and even create equipment useful for battle.
You'll feel a connection with him even when you're apart.
