The Hatoful Kareshi manga has been updated again. Since last time I checked, Yuuya and Shuu have been added.
As always, every chapter is split into a bunch of bird form vignettes that stick to the Hatoful Boyfriend plot, and then a human form side story that freely includes HolidayStar stuff. STOP READING AND SKIP TO THE NEXT CHAPTER WHEN YOU SEE HUMAN FORMS. Because, you know, spoilers.
Totally worth it because Yuuya's chapter is amazing and I'm totally reading all of his lines in the ravenworks Yuuya voice. (And Sakuya's retorts in mine, of course. COUNCIL PRESIDENT CORRECTION KICK!)
And the Shuu chapter has no shortage of icon-ready Shuu pictures if davidn needed another Shuu icon (because I'm still using mine!)
