Jesus Christ and Gautama Buddha , the central figures of Christianity and Buddhism respectively, are living together as roommates in an apartment in Tachikawa, part of the suburbs of Tokyo. While taking a vacation on Earth, they attempt to hide their identities and understand modern Japanese society. Each chapter shows their lives during an average day, when they are sightseeing, drinking beer, blogging, or playing video games. While Jesus is portrayed as an impassioned person for his love for all (even for shopping), Buddha tends to be calm and thrifty, and also likes manga. The comedy often involves visual gags and puns, as well as jokes in reference to elements of Christianity and Buddhism; for example, Jesus creates wine from water in a public bath and Buddha shines when excited.
