At 2 am, Mob wakes up to a message from Reigen. “Mob, are you awake? I’m about to take a ride in the Shinigami Taxi.” Shinigami Taxi? Reigen calls Mob and fills him in. It’s a taxi operated by a Shinigami that mainly carries spirits, but every so often, it’ll take a human on board. “A client of mine asked me to rescue her boyfriend who got into that taxi.”

Following this conversation, Mob finds he can no longer get in touch with Reigen. ”…I have to rescue shishou.” And so, Mob’s journey begins.
