Appeared.

Season 0
A mysterious man with also mysterious motives.

Episode 6

Visits the police station where Kasuga Ichiban and Jack Garland are incarcerated, and informs something to Ooishi Kuraudo that makes him grin devilishly, likely something related to something Ooishi knows...

Episode 7
Ichiban spots the shady figure in the McDonalds bathroom, and remembers Jack's words: "Be aware of Chaos lurking in the bathroom", and follows him through the back door.

The man appears behind him in the alley, and Ichiban asks what he was doing with the cop and if he ordered their arrest. However, he refuses to answer and asks him to take a step back, so Ichiban readies his fists. Through the calling of a (strictly non-canonical gameplay element) Poundmate, he manages to defeat the strange man. Sinbad and Jack arrive just as the fight ends, and the man decides to flee from the unfair situation. Moreso, Sinbad advises Ichiban and Jack not to pursue without planning, because that man is the right-hand man of the dragonlord, Seeker, a dynamic and magnificent enemy. Moreover, they'll need to be careful around the city now that they are known, especially with a face like Sinbad's.

Once they leave, a dimes figure silently approaches at a distance to them...
