Singular contact: Falls & Rises

With a new school year a new threat gets brought to the city and once again, Sonic will have to face it, along with his friends and later also with help of a new ally, who might possibly become his close friend as well. There will be many ups and downs for sure and the task to protect the citizens from the new villain(s) won't be easy even a bit for our blue blur. Will he manage to defeat that villanous threat and save the city from a catastrophe?
If you read, you'll find out, I won't tell you >:)
