I Fused with my Enemy (The Story of Iblis)

A year after Sonic 2006, Silver The Hedgehog mourns for his friend Blaze's death. However, in another dimension known as Dimension Omega, Mephiles The Dark fused Blaze's soul with Iblis and lied about her resurrection. After a year, Iblis begins to think that being fused with the one that stopped her in the past was no ordinary mistake, she continuously hunted down Silver, and Sonic with no luck. After another year, she begins to feel different. As if she knew what she was doing was wrong. She begins to help others and everyone sees that as weird as well. When this gets the attention of Silver, he begins to investigate these roumers, and find out what really is going on
