"How were Gaia Memories created?" "Why did W begin to fight?" To answer Tokime's questions, Shoutarou quietly begins to tell a story. He speaks of his meeting and parting with a man he admired and called his old man—his mentor, Soukichi Narumi. Mysterious people called Dopants, who utilized the powers of Gaia Memories, had begun appearing in the shadows of Fuuto, the windy city. A young Shoutarou had become an assistant of the detective Soukichi and, though called half-baked, began to follow in his footsteps. Unaware that, in addition to his detective work, Soukichi was secretly acting as Skull, Shoutarou began to grow frustrated with his mentor. That was when the Narumi Detective Agency received a phone call—a request from Hell inviting Shoutarou and company to a fateful night! When Shoutarou tracked down Soukichi to deliver the "trump card" bestowed by the mysterious caller, what did he see? Shoutarou and Philip. The one detective made of two and the night when Kamen Rider W began. That whole story will finally be revealed. (Source: Official site, translated)

An untidy room. Empty beer tins, empty wine bottles, a half-empty glass of whisky... A girl is getting up absent-mindedly and starts preparing herself. YOUR morning starts. Lazy and hard-to-wake-up YOU. The emoticon is ME watching over YOU. I play tricks on YOU, while YOU are playing the guitar and drinking. One day, in town, YOU walk past THE CHILDHOOD FRIEND who is buying an Anemone I liked, and remembering that I liked them, YOU rush out to buy them.

When exiting from the room with memories, a picture of the Anemone that YOU painted is displayed in YOUR new room.
