After leaving the military, Shoukaku returned to her hometown to lead her family.

In this old-fashioned and smokey town, Shoukaku’s family has been running shipbuilding business for almost half a century, and Shoukaku was ready to bring the business into modernization in her own way.

"These facilities need to be replaced as soon as possible," Shokaku said, and the things she saw when she was in the military, gave her the idea to do so.

To start her ambitious plan, however, some obstacles must be removed: competitors and local police forces who were investigating their illegal fund sources.

Shoukaku had a couple of new friends as she was in the military. Among these friends, some of them had a strong influence on both the military and the government. And Shoukaku tried to ask these friend’s help to make certain materials exclusive to her family.

The valuable materials that Shoukaku was asking didn’t only be perfectly compatible for shipbuilding but the key parts for some experimental weapons like railguns, and if she could manage to get these oversea materials, she could take the lead of the business.

“The world is changing, and it is changing fast,” Shoukaku said, “that’s why the order is always built by the one with its finest.”

Being the top of one business also meant being the largest target of other parties, but Shoukaku had been fully aware of it since she set her foot on this town again.
“This is only the beginning, that’s why I would need your help, Zuikaku, and Nisshin-san.”
