Special ChaptersEdit


  • According to a now deleted tweet by Nogi Yasuhito, the original plot for Astral Buddy didn't have Shokuhou Misaki showing up at all and Kongou Mitsuko was supposed to appear sometime around the second or third chapter, but all that changed when developing the plot into an actual manga.[8]
