After that, he ended up in a restaurant called "Healthy Kitchen", and found out that "all healthy food" tastes bad in that world... "A tasty, yet healthy food is just a pure fantasy."

However, what was actually served to Touya, who anticipated some awe-inspiring another world food, was something that is far from what he expected... With his Nutritionist Knowledge as his weapon, will this ex-office worker be able to turn around the entire norm in the other world!?
