i know you cant 100% the book until EX4 is out but i have to know is the genocide shop keeper fight in that book? i dont want to do a genocide run just want to know if i can still 100% the book once EX4 is out.
From my own experience nothing in Genocide seemed to complete more pages of the book. It seems Hyakki's info is filled by getting her My Room in True Mercy end, though I don't know if Genocide would fill some of it as well.
