■ Comment from Nanako Aizawa
I'm Nanako Aizawa, and I'll be playing Emma Green.
I've been involved in cars and racing for a long time, and have seen many drivers' backs, but I never thought the day would come when I would be driving myself...
I have met many loving fans of "Initial D" and "MF GHOST" so far, so I feel very humbled.
Emma is a stoic driver who is active at a young age in the tough world of racing. Her relationship with Kanata is also a point of interest!
I will work sincerely to convey the appeal of my work and the fun of cars and motorsports to as many people as possible. Thank you for your support!
