Isomaki

Isomaki is professional, dependable and discreet. He performs his duties without drawing attention away from Akira's work and responds quickly when his employer needs transportation.

The anime gives little information about his private life or interests. His characterization is almost entirely defined through his reliability as Akira's chauffeur.

He remains calm even when transporting Akira during urgent situations connected to Aoi and SOL Technologies.

Isomaki is an experienced chauffeur responsible for driving Akira around Den City and ensuring that he reaches meetings and emergencies quickly.

He has no established Deck, LINK VRAINS avatar, hacking abilities or supernatural powers. His contribution is entirely practical and occurs in the real world.

Isomaki appears as Akira's driver during the SOL executive's investigation into events surrounding Playmaker and the Knights of Hanoi. He transports Akira to meetings and waits nearby when necessary.

After Emma provides Akira with an urgent anonymous tip, Isomaki waits outside SOL Technologies and immediately drives him toward the hospital where Aoi is being treated.

He later continues performing the same role, including transporting Akira to a meeting involving Emma and Aoi as their cooperation surrounding LINK VRAINS develops.

Akira Zaizen is Isomaki's employer. Isomaki drives Akira Zaizen to meetings, work-related destinations and urgent personal appointments.

Emma Bessho indirectly assists Isomaki by providing information that allows him to be waiting for Akira Zaizen when urgent transportation is required.

Aoi Zaizen is Akira Zaizen's younger stepsister. Isomaki drives Akira Zaizen to the hospital when Aoi Zaizen's condition requires his immediate attention.
