It's been 20 years since The Incident that cost Sonic his body and his friends their lives. Now free of the control of the demonic entity called Xenophanes, Sonic the Hedgehog is a suicidal mess, cusses out anyone who tries speaking to him, and completely hates Shadow.
Can Tails spending a night in an abandoned pizzeria with him help his mind heal?
==========================================
This story is based on a Five Nights at Sonic's Roleplay with some extra things sprinkled in (FNF VS. Sonic.EXE, Mario's Madness, etc, etc)
As such, this is obviously not thoughtfully written, characters may be out of character due to interpretation. That aside, enjoy!
