Quoted By:
The first sports festival was in chapter 21.
The first culture festival was in chapter 26.
The first graduation ceremony was in chapter 45.
The second sports festival was in chapter 87.
The second culture festival was in chapter 90.
The second graduation ceremony was in chapter 103.
The third sports festival was in chapter 141.
The third culture festival will probably be chapter 144 or 145.
If the third graduation ceremony is (optimistically) 15 chapters after the final culture festival, that will happen around chapter 160, which means the series will likely be over in less than 20 chapters. Assuming no new anime adaptations happen and ~1.2 months between chapters, it may very well all be over in less than 2 years. Hidimari Sketch as a franchise will be old enough to stand next to Yuno and Miyako during their graduation.
