I totally agree with you about it not being your typical isekai, not at all! That duality you mention between what he thinks inside (all nervous!) and what he projects on the outside (the imposing overlord) is what makes it so addictive. There were times when I laughed alone watching him panicking internally while delivering epic speeches! The visual quality has noticeably declined in recent seasons, which is a shame, but the story and strategy are still engaging. Great review! 👍
