Speed-o'-Sound Sonic vs. Paradise Group and Hammerhead is the battle between the assassin Speed-o'-Sound Sonic and the B-Class criminal Hammerhead and his followers.


Hammerhead and the Paradise Group threaten the life of Zeniru, who they believe to be corrupt. During their rampage, they defeat several riot cops and the top C-Class hero Mumen Rider. Zeniru is told to hide but refuses to do so, because it would ruin his reputation. Sonic then proclaims he will kill Hammerhead and his followers.


As the Paradise Group closes in on Zeniru's home, Sonic confronts them and kills several of them. Hammerhead then throws boulders at Sonic in an attempt to crush him, but Sonic dodges the rocks. He then tries to crush Sonic with a tree but Sonic gets behind Hammerhead and hits him with a kunai.


Sonic calls Zeniru and tells him that he's dealt with the Paradise Group and that the body of Hammerhead is there, only to find out that his body isn't there. Hammerhead has run off into the woods and is lucky that the kunai hit his head.
