Japanese title: 潮ダイアリー
Artist: Otoufu

A twitter account series where Ushio describes her daily life, mainly having to do with other KanMusu, especially her division mates and sister ships Akebono, Oboro and Sazanami.

Many of the days involve references to some sort of anniversary of some obscure event or a minor holiday. (I.E. They go bowling on Bowling Day.) The series also frequently uses numeric puns called Goroawase to create its holidays. (8/7 becoming 8 -> hachi -> ha -> ba, and 7 -> nana, thus making 8/7 "banana day".)
