Well, that was fun. Still in-character, though, so that's good. Tsukune witnessing Ruby's fantasy firsthand was the most fun part, and the ending of this chapter was quite the heartbreaking cliffhanger. Looking forward to your next chapters.
Not off to a bad start by any means. Heartbreaking as hell, but everyone is for the most part in-character and their actions and reactions are fully understandable. Out of everyone, I'm not surprised Moka would take this the hardest, as she saw firsthand what trying to be with multiple women did to her father's relationships with those women (one of whom being her mother), and that is definitely the not-so-nice side of a harem arrangement. I am hoping she and Tsukune reconcile down the line and Inner Moka realizes that Tsukune is not the same man her father is/was and can be trusted to love her and the other girls equally. Also, as Mizore is my favorite girl in the Rosario+Vampire main cast that isn't Kurumu or Inner Moka, I am really hoping she gets some time with Tsukune, too. Keep up the good work.
