Secret Ansem Report 12

Apart from Namine, Nobodies retain their memories of their time as humans, but Sora's Nobody, Roxas, has lost Sora's memories.

This is likely because Sora's time as a Heartless was short, having recovered his heart and returned to his human form soon after leaving behind Roxas, his Nobody.

It would seem Roxas is much like Namine. Namine is Kairi's Nobody, but came into being via Sora's body and soul.

Likewise, Roxas is Sora's Nobody, but was left behind because Sora's Heartless regained human form using Kairi's heart instead of his own.

It may be that Sora's memories are slow to return because the half of him that Roxas is still lacking.

I must convert Roxas into data and return him to Sora.

As a member of Organization XIII, it was exceedingly difficult to bring Roxas in. Having lost to Roxas once, Riku laid everything on the line and used the power of darkness in their second battle, only just managing to bring Roxas back with him.

But Organization XIII grows ever nearer. Here, Twilight Town, is where Roxas was reborn as a Nobody.

This is where Roxas first encountered Organization XIII and joined its ranks. They are bound to search this place throughly.

First I shall convert all of Twilight Town into data and construct a "world duplicate" in Sora's memories. I shall place Roxas within that world to live out his days and regain those memories.

There is little time.

The Organization's schemes must be making steady progress as well.
