hitman, Oswald is the master
of the legendary art "Karnoffel" used for executions. Ash
requested for Oswald to
join the tournament based on rumors he heard about him. Since neither knew
much about the other, the conditions for joining the team was decided in a
poker game; the winner would choose to do what they pleased. Despite having a
winning hand, Oswald recognizes Ash's skill and accepts defeat - he introduces
himself to his teammates then.
It is revealed at the
end of the tournament that Oswald joins Ash and Shen Woo
to obtain money and drugs named 'Dragon Pills' (or 'Ryu-gun' in Japanese). Ash
agrees to give information regarding the drug to him, explaining that it can
only be given to him if he defeats the provider's enemy, Shen Woo. As Ash left
Oswald and Shen alone by themselves, a battle between the two took place, the
winner of which has yet to be revealed; though the confirmed survival of both
Shen and Oswald makes either outcome equally plausible.
