Under the leadership of a striking dark elf boss who possesses the formidable ability of magic resistance, Jiro dives headfirst into these perilous depths day after day. Trading his miserable corporate life for a thrilling otherworldly occupation, he embarks on a brand-new chapter where his skills are finally put to extraordinary use.
