The key to restoring the Goddess's divine power is saying "Itadakimasu" and "Gochisousama"!? A food and etiquette-spreading adventure fantasy featuring the reincarnated adventurer, El!! A man who died after being caught up in a hero summoning meets Fermiena, a goddess living all alone in the divine realm. Seeing that she has become so weak from no longer being prayed to by people that she can no longer deliver oracles, he decides to help her restore her divine power. After successfully reincarnating in another world, the man—now named El—discovers that the Japanese customs of saying "Itadakimasu" (let's eat) and "Gochisousama" (thank you for the meal) are effective for restoring her divine power, but he struggles to spread them. Upon turning 10 and becoming an adventurer, El gets a cook he met through a quest to make "hamburg steaks" and "hot dogs," which are popular in Japan, and they become an instant hit! Seeing this, El resolves to spread the words for divine power restoration along with these dishes, and triumphantly begins his journey of missionary work!ssss
