For that kid to show up at the court at get mad at the opposition shows that he sure as hell should not be in a court. Touma, as we've seen time and time again, doesn't give a flying fuck about anyone besides his sister and Mizuhara, and he always looks at the facts. Tbh he ain't very human, but that's a good thing in this scenario at least. Also, Touma case is true, sadly, the law doesn't make special circumstances, even if something might happen bringing him back to Balkia, Belgium has no jurisdiction.
