Only two floors. First floor is half adult manga/hentai while the second floor is half dojinshi. There is plenty of space though to browse around and they have tons of doujinshi there. Some cheap figures and a whole row of shelves dedicated to body pillow cases. If you want regular manga they have that on both floors as well.
