Tukson's Book Trade

Tukson's Book Trade is a store owned by Tukson. It is located in the City of Vale and is first seen in Best Day Ever.

Best Day Ever
Emerald and Mercury Black enter the small shop during the first episode of Volume 2. They confront the owner: Tukson, and ask him about the stock and specific presence of certain books. Upon finding out the store doesn't really hold "all the books under the sun", Mercury and Emerald both get more serious, and start interrogating Tukson on how he was going to vanish, and run from the White Fang by moving to Vacuo.

Tukson  and Emerald keep exchanging words, with Tukson answering "Yes" in a grim tone each time, until finally, she starts a conflict, and simply asks: "Are you going to fight back", to which he screams "YES!". Tukson lunges forward, misses his strike against Emerald, and falls right into Mercury, who both kicks and shoots him in the face with his boots, killing him instantly.

Merchandise
The store's windows and name clearly state it is a book store. Upon entering, there are many books, lining the shelves in an organized fashion. Comics remain at the front, with novels in the middle and back. There is a back room, which is presumably an office, and the three windows of the shop can be dimmed, to be made opaque, so nothing can see through them.
