Koei Tecmo and Ruby Party have major plans to mark the 25th anniversary of Harukanaru Toki no Naka de. They've revealed a brand-new mobile title, Harukanaru Toki no Naka de: Ryuuguu no Miko. This beloved otome series began its journey on the original PlayStation back in 2000.

Pre-registration for this adventure RPG is now live. However, the launch is currently confirmed for Japan only, with a target release date of December 15. There is no announcement yet regarding a global version.

What’s the story?

This latest installment transports you to Ryugu, an undersea kingdom governed by the dragon god. You assume the role of a modern university student, caught in a violent storm during a trip to Dan-no-ura and washed into this otherworldly realm.

As monstrous beings darken the sky, you are rescued by a man in a kimono named Kiyomori, who vows to guide you and carries you into the ocean's depths. There, you are anointed as the Divine Child, tasked with safeguarding the flow of time and space alongside the Eight Leaves—heroes summoned from various periods in Japanese history.

Life in Ryugu blends the mundane with the magical. You'll share a home with the Eight Leaves, enjoying daily interactions like seasonal conversations. These small, bonding moments lay the foundation before embarking on grander quests.

Romance is a core pillar of Harukanaru Toki no Naka de: Ryuuguu no Miko. Your choices determine whether relationships with the heroes blossom into deep friendships or passionate love stories. Intimate, everyday scenes—like falling asleep beside your chosen guardian or listening to his voice as he drifts off—add a layer of tender closeness.

Each of the Eight Leaves hails from a distinct historical era, such as the Heian, Sengoku, and late Edo periods. Journeying to their times forms a crucial part of the story, where you'll confront enraged deities.

If you're in Japan, you can pre-register for the game on the Google Play Store. For everyone else, you can enjoy the latest trailer below for now.
