Sakura

As a member of Tetra Line's crime management squad Underworld Queen, Sakura leads the "Seimeikai", a criminal group that styles themselves after the yakuza syndicates of old. Despite running a gang in many respects, Sakura holds herself and her subordinates to a code of honor and ethics, preventing her gang from catching too much attention from the authorities.

As no one in Seimeikai actually knows Sakura is a Nikke, she is sometimes subject to issues that plague yakuza, such as pressure to ensure a line of succession, though that's a far preferable alternative to what the gang would likely do if they did know she was a Nikke. A woman of principle, the Seimeikai refrain from engaging in immoral acts thanks to her leadership. Under her guidance, the Seimeikai has become an organization with a well-deserved reputation for its honorable conduct.
