The first gossip from Sengoku Basara Magazine vol. 10
The Sengoku Basara Magazine website has now updated along with a preview article on the Dengeki site. The correct reading of the name of the new scenario novel is apparently Sengoku Basara 4 Sumeragi Riten Daisakai (‘The Grand Tea Ceremony Cast Out From Heaven’).
My copy won’t arrive in the UK for a few days so I’ll summarise the information I’ve found about the new issue so far.
The website update formally confirms that Sengoku Basara 4 Bontenmaru-hen will be released in compiled book form on 26th September 2015, priced at ¥616. They also included the cover artwork, which is rather understated for a Sengoku Basara manga.
