I was tempted to phrase the first sentence as "I hight Nagato of the Sakura Empire," but that seemed a bit too archaic, even considering her use of yo for "I" and nushi for "you".
Like where's the second part of the Southern Hime battle?
That was a physical-copy-only work from Comiket, I believe. Some of the story arcs here, are only teasers/samples from upcoming books Hisa has/will put out.
