In a world where the conflict between Azur Lane and the Red Axis was overcome, and the Sirens were repelled- The Samoa Base from that world was suddenly summoned to a war-torn other world!? Amidst the chaos caused by clashes of values and common sense, this is the story of a young Commander and the KAN-SEN (some of whom are... troublesome) as they charge through the stormy seas of another world. And so, it begins! NOTICE This is my first post. This story is a crossover between Summoning Japan and Azur Lane, with characters and weapons from various other works mixed in. It also includes original lore, theories, and some convenient plot devices. Note that the summoning to another world happens two years earlier than in the OG Summoning Japan. The author's knowledge is "broad but shallow" (self-proclaimed), so there may be many mistakes, contradictions, typos, or awkward phrasing regarding politics, military affairs, etc. If you notice any, pointing them out in the comments would be greatly appreciated. I'll do my best to make corrections where possible. Also, this work is written on a sudden burst of inspiration, so updates will be very irregular. Please bear with me. PART 1 RELEASE: 2019 (TL INCOMPLETE)
