Isekai'd, My Posterior!

Getting Isekai'd normally meant rocking up in a snazy town that had a snazy magicy name with a couple of snazy babes to join your unofficial harem. A lot of snaziness involved. That was not so here, however, especially when you explicitly did NOT want to be the Chosen Undead. Therefore, there was only one plan: Make someone ELSE the Chosen Undead. I mean Oscar's RIGHT there.
