Alrighty then! Now we've got nine of us Shiratsuyu-class gathered!

Let's have a commemoration ceremony for Umikaze and Kawakaze then!

Here, Umikaze!

Here, Kawakaze!

You have been acknowledged as the sister with the Number One brightest hair colour out of the Shiratsuyu-class.

You have been acknowledged as the sister with the Number One lowest stroke count out of the Shiratsuyu-class.

Okaaay! Now we're all sisters!

Let's all get along!

What the heck...

Yaaay!

Woooow!

Haha...

Hell yeah!

Seems that Shiratsuyu-chan gives all of her sisters their 'Number One', one-by-one.
