Sometimes anime can feel quite intense. They intensely focus on mechanics and ideas, exploring them to great depths. Usually, this leads to stories that are well-developed, interesting, and engaging. Essentially, they are thematically dense, and even iyashikei and typically cozy anime such as Yuru Camp, Do It Yourself!!, and Super Cub explore their themes in great depth.
