Easy zombie apocalypse + imaginative hoarding + low-key development flow. The overall tone is the contrasting humor of "others are struggling to survive in the apocalypse, and I am doing logistics in the apocalypse". The tension comes from the threat of zombies and the struggle for resources, but the solution is always carried out with the protagonist's unique sense of relaxation and mean humor. It is not a traditional apocalyptic story with great suffering and hatred, but a battle of wits type apocalypse where "you can win if you just hang in there".
