I remember Wonder being able to read books about Closer & Soy's persons, does Wonder ever get books about his other teammates personas? Should I keep checking the bookshop?
I just checked in-game, and there should be books for Janosik, Rob Roy, Awilda, Mandrin, Chiyome, and Ghino in the game! I don't remember when Ghino's was added, so I'm not sure if Global has it yet.
Rather than checking the individual bookshops (I think there are at least three- in Shibuya, Shinjuku, and Jinbocho), it may be easier to just check the books section in the online shopping menu (assuming you've started Mio's Synergy and unlocked it)? That should let you check what books are available across all the shops in the game at once, rather than running between them.
