There's a user-added tag that says, "An existence that can only take up the lower-left corner".
EDIT: More user-added tags include: "Please let her grow up to be responsible (Begging)" "Slovenly elder sister" "Not you, sit down!" and of course, "Cute KanColle"
You don't have to change Sakawa you're amazing for me already.
Be that as it may, when the time comes she should grow to her full potential and live life to the fullest. No reason to not better oneself. Also genetics will do their thing regardless.
Oh, and the chibi-Agano in the corner is adorable. Hopefully I make it to the later maps where I read she is a reward for completion.
