DeVille Hückebein
DeVille first appears in chapter 4 of Force, when Arnage contacts Veyron via videophone. In chapter 5, he and Fortis greet Veyron upon his return to the Hückebein base. They inform him that TSAB has reformed the Riot Force 6 to secure the Divider, which means that they will attempt to arrest the Hückebein members, as well. However, as long as Hückebein is in possession of the Divider, TSAB cannot lay a finger on them. (Source: Nanoha Wikia)
