Alice was a shy girl who was part of a small friend group. She was a bit of a nerd, having an obsession with the character Ultra, but this was a quality shared by her friends. They were friends not just because of their interest in Ultra, but their interest in creating a game about him. They had been working for months on a game where they could have fun playing as the characters. And eventually their idea came to bear fruit. After lots of work, they had finally finished their game, and the only thing left to do was to make sure everything was working.
Her and her friends all had their favorite characters, and saw it through that were added to the project. When they were testing they all clung to their favorites and transformed into the vessels they had constructed for the project. Everything went smoothly, the vessels were fully functional, and they had innocent fun role-playing as their selected characters. There was one notable character left out of their fun however, that being the main character himself, Ultra. He was in the project because he was the protagonist, but he wasn't the favorite of any member of the group. However, the vessel would not go unused.
Y found the group and decided that these few were his new toys. His old and new vessel mixed as he transported himself from his current body into the unused Ultra vessel.
Suddenly, in the middle of their play, as the friends prepared to exit their vessels and leave, they realized something was wrong, and they couldn't get out of the vessels. They were trapped. As they made this realization, "Ultra" showed himself. The group realized that someone had tampered with their project, and he was standing right in front of them.
Immediately, one member of the group decided to confront this strange individual. Their prompt response was tearing them apart faster than any one of them could react.
The group was thrown into chaos, one tried to fight but failed, another tried to hide and was found immediately. Alice, among them, decided to run in her fear.
