A small auto repair shop on a street corner in Los Angeles. There, a quiet young man named Robbie Reyes was silently servicing a car today as well.

At first glance, it's just an ordinary auto shop found anywhere. However, this was also a bit of a base for the members of the Samurai Outriders, where they occasionally gathered to maintain vehicles and exchange information.

One such day, a person named Guest visits the shop. Did they bring in a car as a customer? Did they start working there as a new hire? Or did they come to get involved with the Samurai Outriders?

And so, a new story beginning from an auto shop opens its curtains.
