I just realized that this is probably a Slam Dunk parody, with the talent not fitting in with the rest of the team.
If you read the whole thing, It may also be a reference to the whole "ridiculously hard ship to get" thing (on top of that). In one of birii's doujins (the one about smoking), there's a short piece about Yahagi and Mikuma being ridiculously rare drops that caused ships involved in attempting to farm them to have traumatic flashbacks.
Iowa wasn't hard to get in this event (since she was a map clear reward), but Birii being Birii, of course he did the entire damn thing on Hard. And, well, E-7 on Hard? I was there. I got all the way to Last Dance. It was not a pretty sight.
E... exceptional? What?To Japan♡Nice to meet you, Iowan... Yahagin and I were just talking about how we've never before seen such an exceptional talent as yourself.Yes. This will likely take some getting used to... so don't get too discouraged.It's already been a month since I got here...One month later.You'll see...Wait a sec, what do you mean...Er... eh?Introduce... uh?Well, first things first. I should--Hmm... this place isn't half bad.The First Fleet has returned!! Victory at last!!I'm looking forward to it!!Hey, what's with the 'murican ship!?Good!
