(Edited because I'm restarted and thought June is in the past)
Hukyu is an online publication by GAMABOOKS, and GAMABOOKS is an online bookstore ran by VTubers Touka Fuyu and Moroboshi Meguru. It will be on sale from June.
The topic of the first chapter will be "Folklore in VTubing," with the contribution of Kwansei Gakuin University's folklorist researcher professor, the person behind the YouTube channel/podcast ゆる民俗学ラジオ (Laid-back Folklore Radio), and the editor Moroboshi Meguru, a VTuber specialized on folklore.
The second chapter comprises of interviews from people active in the virtual world. Among the topics, you'll find: the history of virtual culture, the possibilities of metaverse, predictions for the future of VTubers etc. In this chapter, many VTubers and related personalities will be interviewed, such as "Beautiful Virtual Girl Nemu (バーチャル美少女ねむ), who's been active since 2017 and is the author of the award winning book メタバース進化論 (The Evolutionary Theory of Metaverse), or otaku subculture writer Tamagomago, who's contributing to several other magazines and has written many books, or Kosaka a rapper of the MZM music unit and the guy who's participated in Raden's birthday stream (iirc).
The third chapter is about the question "What is a VTuber?," regarding which they interviewed many VTubers to share their perspectives, while the fourth chapter will be about the same topic, but this time the interviewees are not VTubers, but people related to virtual culture, such as entrepreneurs, managers, illustrators, producers, or the Waseda University's VTuber Research Group.
