Death and Rean passed through the colored Portal and fell directly into the River of Forgetfulness. Both Death and Rean's Soul started to change shape almost immediately after that. Their minds got fussy, and they couldn't tell right from left. Still, Death made sure to hold Rean and not let him escape.
Suddenly, both Soul lost their shape. At the same time, they were being converted into Pure Soul Energy. But it was at this moment that that faint Light inside Rean's Soul started to get brighter! Both Rean and Death's Soul Energies then began to revolve around it together.
That Light then started to gather all their memories and emotions. Not only that, but the Light also started to change! What was just a White Light before, now became half White and half Dark. However, Death was right! That Light really had the power to keep both of their memories somehow. Unfortunately, Rean and Death already lost consciousness.

Death and Rean, obviously, didn't hear or see anything.
The River of Forgetfulness tried to take those memories away, but the Light's power was a lot stronger than it. In the end, every single memory, emotion, or anything related to that was sent into that Light. With the memories disappearing altogether, the River of Forgetfulness felt like its target was gone. The River didn't have a mind. It only did what it was supposed to do. With no more memories to wipe out, it would simply start the next process.
Both their Soul Energies were then released by the Light so that the River of Forgetfulness could do its job. The cleansing process went for several years, but during all this time, both Souls had always stayed close to the Light of their Memories.
Finally, both Soul Energies finished passing through the River of Forgetfulness. From there, they seemed to be dragged by some kind of supernatural power, which tried to send them into another portal. In fact, that power was supposed to get just a single Soul each time, but the Light acted as a glue that kept Death and Rean's Soul Energies together.
But there was a problem. The moment that Rean and Death Soul Energies were about to enter that Portal, that Light began to get even brighter! The space around it looked like to distort, and the Portal where they were supposed to be sent into disappeared. Right after, another portal that wasn't supposed to be there materialized right in front of both Souls.
That supernatural power from before tried to stop Rean and Death from falling into it. But the Light also acted as a barrier that prevented that power from getting close. Rean and Death Soul Energies then passed through this new Portal, which closed right after they entered.
Usually, the Portal that disappeared would send Rean and Death to be reformed as new Souls. After that, they would enter a new life form that was being created. Like a baby, for example. That would then conclude their Reincarnation Process.
