I have to say that for Hino sensei to make these sort of "fillers" was an absolute, brilliant idea. The ending upon volume 19 was of some content, though with them saying she does end up with Zero kinda leaves a blank and immediately skips to 1000 years in the future with her daughter from Kuran and her son from Zero, though I really like how she shows on how she raised Ai and Ai's first love (not saying) and how she got together with Zero. I also love the fact she includes the stories of other characters such as Wakabe and Aido, Kain and Ruka, as well as Headmaster ;) What are your thoughts?
