Bruno did not immediately answer the request to visit Japan, or more specifically its capital, to meet with the Ruling Dynasty of Japan. Rather, he would do so at his own leisure. It was nothing urgent and could wait for some time.
Emperor Meiji had sent a letter that traversed by sea and railway to the German Reich, requesting Bruno to visit and witness what his passing thoughts had given birth to: a rather exceptional machine gun for the time. It was something that was most certainly superior to anything fielded by the Imperial Japanese Army in his past life.
Or at least it had the potential to become such a weapon once it had gone through proper prototyping, experimentation, and so forth. It had taken roughly four years for the German Reich to go from the conceptual stage to passing military trials for the small arms Bruno had given them.
