Tsuyoshi Mukouda, a corporate employee, is unexpectedly called upon as a savior in the realm of Reijseger, an alternate world that needs protection from its foes. Suspicious of the monarchy"s motives, he discovers the nobles' hidden agendas. Mukouda persuades them to back off by leveraging his seemingly useless talent, "Online Supermarket." Yet that skill turns out to be invaluable. Mukouda can acquire inexpensive Japanese groceries and kitchen tools—items that are treated as extravagances here—for a modest fee. While preparing lavish meals with this advantage, he attracts the attention of the legendary wolf Fel. The beast quickly seals a pact to serve as Mukouda"s familiar, drawn irresistibly by the gourmet fare. Together they roam the land, where Mukouda earns a living as both explorer and trader while relishing sumptuous dishes. His cooking becomes a source of intrigue, drawing allies and enemies alike. He secures safe passage and trade rights.
