Back in the late 2000s and early 2010s, there has been various debates about moe. Despite the critics, moe in general has eventually became mainstay in modern anime
I feel the main reason moe actually saved anime is of course the adaptations of Manga Time Kirara series and Houbunsha, a Japanese book publisher that is behind it all. The first few series in 2007 started receiving anime adaptions. The first being Hidamari Sketch and Doujin Work. After that, the rest was history after K-ON aired and became wildly popular.
Since the 2010s, there are usually anime adaptations of series from the family of Manga Time Kirara family of magazine air almost every season. Sometimes, there might be two that air in the same season. You might be wondering why I think Manga Time Kirara is the savior of anime and why these magazines are popular? I will explain why.
