(Third-person POV)
The Dream had managed to create his own, perfect little world, but he knew that he would fade away and disappear unless he had his little human sacrifices to shape this world for him, to do the work for him and make it ongoing. These sacrifices, chosen to play the part of "Alice" and wander the forest until death, would do what they wished until it caught up with them. The Dream needed to have the Alices all die in their own time and be replaced by the next unlucky victim in order to keep himself from vanishing. Very selfish, yes, but he would not give of his idea of perfection, of eternal life...
The Dream started out as just a normal dream, but he realized that, like any dream, he would vanish soon. He could not accept that he wasn't immortal and wouldn't allow himself to fade away, do he decided to live forever by allowing people to shape their own world.
So, the first Alice was chosen. Her name was Meiko, she was from Hokkaido, and she fell asleep one night without ever waking up. Instead of letting her fear control her and cause her to hide, she took initiative right away and decided to kill anyone who stood in her way. She was merciless, using her sword to wrathfully cut the throats and stab into the hearts of her opponents, giving her much power. But, this power was not gained by the love and respect of the people, as power should ideally be obtained, but rather from their fear. So, like all power unjustly gained this way, it collapsed when the people whose lives were shattered into pieces by her corrupt rule finally rebelled and took her into captivity, punishing her and executing her for her sin and violent ways.
The second Alice's fate was not much brighter. His name was Kaito, and he was a singer and songwriter from Tokyo. When he arrived in this Wonderland created by the Dream, the very first thing he noticed was all of the sadness and suffering that surrounded him. He, as a compassionate and kind person, was filled with grief instantly and expressed this emotion through his voice. All day long, all night long, Kaito would sing songs revealing the misery and pain that he had witnessed, convincing the other beings occupying the forest of the truth and gaining many followers. Eventually, he eded up going insane and disappearing. It was said that he was shot by a madman, but the one who shot him was none other than himself. Yes, insane and drained of all hope for a better future, this poor young man had committed suicide all alone, with all of the people who valued the musical sounds he brought into the silent, lonely forest grieving for his death.
The third Alice really did change the way life went on in the forest, at least while she was there, and though her time was a little longer than the two previous Alices, she still suffered a terrible fate. She was known as "Miku" and she was a popular singer and Japanese idol residing in the Harujuku district of Tokyo. It seemed like attracting admirers was something that came naturally to her, so of course she adopted that even in this new world. Miku gained many followers, and many lovers as well, which caused her to gain quite a lot of power. Unlike the power that Meiko had, this was attained by the people's love and admiration rather than their fear, and so she was named their Queen. She very much enjoyed her life, which included ruling over her kingdom with kindness and compassion, attracting her many male partners, and attending parties. She enjoyed her life so much that it may have even been better than the live she led previously; and, so much so that she would never be able to give it up. She simply couldn't accept the fact that she would die someday, and she spent every night lying awake and wondering if she could live forever, dreading death. She began to adopt the vices of the Dream, and that caused her to become paranoid, and consumed with fear and darkness she slowly rotted away and died alone in her room.
The Dream began to wonder why his victims died so soon, and he thought it was a shame that they didn't give him more of a show, but he needed to find new sacrifices in order to keep himself alive, so he didn't take any moments to consider the feelings of the people he was using as human sacrifices to the cause of his own personal needs and selfishness. Still, he began to change his tactics in picking these subjects, and instead of looking for someone especially strong, or intelligent, or enchanting he decided to find a pair of twins who were both rather weak, or average at best, but were dedicated to protecting each other and were almost like two halves of the same heart. The Dream thought it would amuse him to test the strength of the siblings' love.
For the place of the fourth Alice, the Dream selected the Kagamine twins, who were still children and were from a smaller town in Japan. The two of them, still being naive kids, explored the forest out of pure, innocent curiosity. They were able to use their talents to get along for a while; with the girl, Rin Kagamine, being stubborn and strong-willed, and the boy, Len Kagamine, being intelligent and eager to understand the ways of the forest, they could figure out how to survive and not fall into the same cruel fates of the previous Alices.
This lasted for a while, but soon enough this adventurous dream became a nightmare for them, as they we just children and weren't strong enough to fight off all the terrors of the forest, of this world created by the Dream, the cruel god of that dimension. A dark spirit took over control of Len's body one night, causing him to go out of control and become a bloodthirsty, psychopathic monster temporarily, and he ended up taking his twin sister to the graveyard, murdering her brutally and then going to find more prey. This entertained the Dream quite a bit, so he allowed the madness to go on for a while longer, until a witch took pity on the poor boy and granted his freedom from the dark creature inside of him.
When Len finally regained his consciousness, he noticed that his twin was missing, so he went to go look for her. After a few days of constant searching, he found her dead body in the graveyard and regained some recollection of him killing her. He was instantly consumed by unspeakable sorrow and regret.
