did anyone else feel like there were a lot of plot holes and things left unresolved in this?
Yeah, definitely...but I think it was supposed to be that way. They want us to be like,
"'Dedicated to the late...MICHIKO TAKAMINE'?!?!? Wha—Wait, is that 'Michiko Takamine' the person, or 'Michiko Takamine' the identity?! Well, it has to be the person, right? Shigeko was RIGHT. THERE! …Or maybe the identity, because Haru wrote it.…Ooooooor maybe it WAS the person, because nobody dedicates a book to someone who changed their identity and says they're deceased…? But wait—the book is credited to "Sakiko and MIYAKO UEHARA!" ...But the last words of the book were right where Michiko left off on her computer! Urrrrrgh…"
