Hellooo! Aoba's come to do some some data collecting!

Oho! You're that transfer student, aren't cha?

Aoba-senpai! Is something the matter!?

I thought I'd put it in tomorrow's Academy Newspaper!

In this Kancolle Academy, as a educational facility attached to Kancolle University,

there is Beginner, Mid, and Upper levels of instruction. (From 'Kancolle Academy School Entrance Guide')
