Hooray for cute Akaga doujins! I also liked how they referenced Kaga's sister ship that was never completed, I like when doujin artists throw in little historical stuff like that.
I accidentally read ''May you sleep well, Akagi-san'' as ''May the sleep be with you, Akagi-san''
That either because I was skimming through the text bubbles really fast, or I just binge watched all the Star Wars movies...
