Sasaki and Peeps, Vol. 4 (manga)

War has broken out between the Kingdom of Herz and the Ohgen Empire...which means it's back to work for Sasaki! From procuring supplies for Viscount Müller to negotiating deals with the Kepler Company--not to mention Peeps putting him through the wringer with advanced magic lessons--he's never been busier. What happened to living the good life in the otherworld?! Maybe he'll finally get the hang of that teleportation spell, at least...
