改二の姿を維持するには提督のパワー（意味深）を定期的にチャージする事が
必要だという設定をワタシの脳内で決めました！

あ、最近改二になった榛名さんこんにちは＾＾

Yuudachi needs to be regularly charged with the Admiral's power (highly suggestive) to maintain her Kai Ni form, or at least that's setting I just came up with!

Oh, if it isn't Haruna who recently gained Kai Ni, Hello^^

Kai Ni, lit. Second Revision, refers to the second upgrade available to some ship girls in Kantai Collection. It is accompanied by updated art, and generally a significant power boost.
