Six episodes in and things are getting worse. They skipped the most fundamental rule of a story. Show don't Tell. We saw no fighting, no battles, no struggles, no hero journey. No romance between the MC and his concubines. Very little with Elise. Sorry but that's just poor writing.
Why is this an Isekai? There is no real quests for the Party, who don't even behave as a party. No danger.
