So we have been waiting seven volumes for this moment, when Shigeru wakes from the coma. We know cousin Sei was there at the cliff where Shigeru "fell," and Sei's possessive-to-the-point-of-madness mother was there, and we strongly suspect knowledge about what happened has brought Sei to the point of madness. Shigeru does not recognize Sei or his mom at the hospital, but at home, when Sei and his mom visits, that moment? Oshimi stretches this moment out masterfully for several pages. Not annoying, nope, but impressive--superior--atmospheric artwork in every respect.
Sei holds firm to his promise to his mom that he will not see his girl friend anymore, but when Shigeru recognizes them. . . . So next volume, which we will see in translation in a year, maybe, we can again read it in a matter of minutes (but I have studied many of the pages closely for the artwork!).
