Akira Nagai (永井明 Nagai Akira) is the president of Nagai Industries.
Akira is one of the few gangsters who knows what the concept of ninkyo chivalry really is. Other Yakuza bosses throughout the Kanto region admit his superiority. However, he behaves like a friendly old man. Because he considers their organization a necessary evil, he pays attention to the local community and runs his office quietly. Akira is also friends with Tom Johnson and often tells him stories about the Yakuza and ninkyo.
- Akira's zodiac sign is Leo and he has a O blood type.
