Helluva Boss Special Mission: Zero Episode Title: Mission: Zero Episode Description: Blitzo starts his human assassination company with Moxxie, Millie, and Loona to exceed their mundane job prospects in Hell. During their first business meeting, Blitzo argues with Moxxie and Millie over the company's ideal killing method; they are further concerned when he reveals he has seduced a member of demon royalty, Stolas, to steal his grimoire used for traveling between Hell and Earth. The meeting is interrupted by Stolas, who assumes Blitzo had taken the grimoire as an excuse to continue their affair. After begrudgingly having sex with him in his office, Blitzo convinces Stolas to loan him the grimoire under the false pretense of further romantic encounters.
