sonic works at the mall. he goes to hot topic and falls in love with the man behind the counter. hijinks ensue.

My personal take on the TMNT & Sonic the Hedgehog mythos, with cues from all over the franchise with OCs involved.

One mysterious emerald grants a young boy a power, a power so ancient that it has been used once in history. Join him and his friends as they journey across high school to become heroes and meet new people that will help him stop the forces of evil. The worlds of Sonic and MHA are one. Soinc characters humanized. Elements of games and shows in it. Harem story. Rated M for Bakugou.
