I hear that there's 'Black Bases' around.

It's great that our Admiral isn't that kind of person,

Nee-san!? That's dirty!!

...But it's not like we can treat it like it's none of our business, can we?

let's give those black bases an embarrassing name...

Without using the kanjis,

we'll just call them Bra-chin, how does that sound? Burakku Chinjuufu

...! In that case...

Akagi-san!? That's lewd!!

I'm sorry.

how about we double it to Brabra chinchin? Chinchin = dick

Like how people call the biker gang "Chinsoudan", Apparently it's a derogatory name referring to the bousouzokus.
