Wolfram initially dislikes humans, even Conrad's father, Dunheely Weller. He hugs Wolfram while saying 'I finally caught you.' Personality Yuuri calls Wolfram even more loud, and he finally manages to wake him up and free him from the consciousness control. Inside, Yuuri finds Wolfram's body possesed by the box former key's consciousness, who demands Yuuri to be quiet because his voice is able to disturb and 'wake up' his vessel. Desperate and worried about his safety, Yuuri manages to forcibly open the box and goes inside to save Wolfram. Conrad tries to open it, but he fails and his hands are burned by the box's flames. As the box was brought from Seisakoku to Big Shimaron by Yelshi during the Greatest Fighter Tournament, being the key, Wolfram is absorbed by the box and trapped inside, at the same time activating the box. It's later revealed that Wolfram's heart is the key to the forbidden box Inferno on the Tundra.

He takes the engagement much more seriously than Yuuri does. When he first becomes engaged to Yuuri he is extremely upset, but the idea quickly grows on him. Afterwards, Yuuri picks up Wolfram's knife, accepting a duel. This leads Yuuri to slap him on his left cheek, a sign of proposal among nobles in their culture. Wolfram shows hostility to the new king, and insults his mother. Yuuri's first day in the capital, he is invited to Celi's dinner with all her sons.
