■Hisaka Thank you for reading the Hifuu compilation to the very end. As this is a compilation of works from a long period of time apart, we ourselves were reminiscing about the past while editing. There aren't many Hifuu books, but many of them are works that we are very attached to, so it is deeply moving to be able to compile them like this. I would be very happy if you enjoyed this compilation even a little. By the way, there were two possible versions of the new manga drawn for this book, and I agonized over which to choose until the very last moment before starting the actual work. In the end, I went with the initial idea, or rather, the one I had in mind when I was creating "Lineage Leading to the End." As a result, I was able to depict what happened after "Disease Leading to Fantasy," which I had wanted to draw for many years, so I am very satisfied. In addition, Hiyori-sensei said that the other version was "too neatly put together and lacked interest." I thought so too, so I hesitated a little, but I decided to stick to my original plan. This compilation marks a turning point for the series, but I still want to depict the adventures of the two Hifuu girls, and I'd like to release another Hifuu book as well. So, thank you again for reading this time. Now, to conclude this afterword, I'd like to quote a line from the final scene of a new manga I drew for another pattern, for which I even prepared a script. "Now, Merry, let's resume the activities of the Secret Sealing Club!!"

■Hiyori Thank you for reading the Hifuu Compilation to the very end! I'm so happy that I was able to put all the Hifuu Club stories together in one volume, as they're all works I'm very attached to. Midway through, the shocking appearance of Sumireko in the Hifuu world caused me a lot of trouble making everything fit together, but I think I managed to pull it all together...... somehow? I hope you enjoy it, including the newly drawn illustrations! See you later!
