We should choose the operation most suited for our naval distrct as a whole. Shall we go with D?

Katori-san, the destroyers you have been raising in DesRon 11 - are any ready for the next operation? Tatsuta's squadron for roughly two years.

I have three that should be able to handle even an A operation.

Then suppose we combine those three with DesRon 1 into the First Fleet? Abukuma's squadron at war's start.

Does DesRon 2 need any replacements, Jintsuu-san? Jintsuu's squadron at war's start.

No, we are fine.

Kashima-san, Kashima-san!

Yes?

"A operation"

"D operation"

What do they mean?

Yeah, yeah!

Is "A" good?

Downgrade...?

D

A

B

So there are 10?

Ah, it's kinda like the Zodiac. The "ten celestial stems" come from ancient China and are an ordering used for calendars and such.

"Ten celestial stems".
