Welcome to the future, the year 2122! Imagine a world where technology has advanced to the point where you can dive deep into the World of Pokémon through an immersive virtual reality experience. Cyber, a tech giant, made this possible by reviving the forgotten Pokémon franchise and crafting a brand-new region called Alyssia.

The driving force behind this incredible venture was the CEO’s child, reigniting the magic of Pokémon for a new generation. Alyssia is a realm waiting for exploration, rich with an engaging and dynamic storyline. To add a twist, the team introduced a new variant of Pokémon, the Rosen-formes, making the experience even more exciting.

However, as with any cutting-edge technology, glitches can occur. Lately, the program seems to be experiencing errors, causing the non-player characters (NPCs) to act unexpectedly. It’s a mystery that needs solving, adding an unexpected twist to your virtual Pokémon adventure.

Get ready to uncover the secrets of Alyssia, solve the glitches, and embark on an unforgettable journey through this captivating and immersive Pokémon world!


You are the son of Cyber’s CEO, the world’s largest technology conglomerate. Pokémon, a long-dead franchise, has been resurrected at your request in the form of an immersive reality simulation that uses a player’s dreams to create realistic experiences and sensations. You are the first to test the system on the project’s launch day, but something unexpected happens – the systems designed to protect you do not, and the fail-safes are disabled, sending you spiraling into a test server known as Alyssia ZERO with no memories or recollections of where you came from.

When Professor Oak tells you that Rosen Forme Pokémon come from the same world as you and that his colleague, an expert on them, has gone missing, your journey begins. Professor Oak believes they used a strange technology to bring you through to this world. He wants to see your impact on the world around you, as these Pokémon have been wreaking havoc on various ecosystems throughout the region.

On your journey, you will come across the mysterious Team Null, who claim to know that the reality around them is not what it appears to be, and wish to reduce that world to nothing, to Null… you will not fight them alone, however, as strangely familiar figures from a life you no longer remember begin to appear to guide you through an ever-changing world within which you do not truly belong.

Shadow Pokémon, on the other hand, have resurfaced alongside this evil. Will you and your allies be able to fight back against the growing darkness?
