Idol of the blue seas

1. Idol of the blue seas!
On a certain peaceful off-day this happened.

Saratoga-chan (and the other girls) are preparing some promotional activities in the home port for the purpose of promoting charity.
Though, this years  theme is...
[To protect the blue seas let's search for the "Legendary Seal" with Saratoga-chan!] -it seems.
Saratoga: Therefore, let's go look for the "Legendary Seal", Commander!
Commander: ...??
Saratoga: Hurry up, hurry up! If you don't then the other girls will find the Seal first!
What... do you mean?
Saratoga: Ah, the commander hasn't heard about it yet? We just got notified that the Legendary Seal was seen in nearby waters.
Saratoga: Instead of just calling for the preservation of marine life everyone decided to go look for and protect the Seal themselves, you see?
Saratoga: Akashi made some special equipment for this too!
This is... the "Legendary Seal Radar"!
Saratoga: Ahhh, must have been quite the difficult task to make that thing.
Lexington: Saratoga-chan, you seem unusually motivated today~ Your sister is so happy to see you like this.
Saratoga: Nee-san!
Lexington: I came here to just submit this report.
Lexington: I think it's good for everyone to take actions in their own to protect the sea.
Lexington: I was wondering if the Commander could help her out in this...?
Lexington: Now, don't bother the commander too much. Okay, Saratoga-chan?
A charity activity to protect the sea? That "Legendary Seal" thing is a bit odd but let's help everyone.
Saratoga: Yeaa! Commander, thank you!
Speaking of, that costume Saratoga is wearing...
Saratoga: Ehhh, did you just notice it?  It ’s “Saratoga-chan, the blue sea idol version” costume, specially prepared for charity live show♪
Commander: O,oh...
Saratoga: The location of the Seal can be discovered by using this radar and my knowledge... yup, yup, for the sake of this task I studied hard, I know everything about the oceans!
Saratoga: Commander, if you have any questions, ask Sara-sensei♪
And thus, I set off in the journey to find the "Legendary Seal".

2. Charity Race?

Aylwin: Hmm... It doesn't seem the Seal is in this area...
Dewey: Aylwin, I am getting a reaction from something over there desu!
Aylwin: Okay! (Lexington-san has her hands full at the moment, so we need to do the best we can on our own...!)
...
Hardy: Hey, Hunter... Remember the "The Great Monstrous Octopus Demon God" that Sara spoke of? Can such a thing really exist?
Hunter: ... Hardy, I have heard that question more than 40 times now. If you are feeling scared then why don't you go back?
Hardy: Scared, Me! Not a chance! Hmph, I am just making sure you don't get surprised attacked and stand around like a deer in the headlight!
...
Jamaica: It's a dream of mine to become a marine biologist and write a thesis on starfish. It's goes without saying I will want to protect the sea..!
Baltimore: Hahah, that's the spirit! We've got to search over there too!
Bataan: Umm, Baltimore, everyone else is heading the other way... Sh-should we really go this way?
Baltimore: Hey, there's no rule that says we must search nearby areas where we pick up readings. Dare to go against the waves and outwit them all!
Birmingham: Aneki... I will continue down the path I choose...!
...
We came across several of the other teams as Saratoga and I were looking around.
It seemed that everyone was taking their respective searches for the Legendary Seal pretty seriously.

Saratoga: Fufun, everyone is so excited this year!

Apparently, this legend about a creature which brings good luck may have contributed to the excited atmosphere.

Saratoga: (Whispering) The part about it bringing good luck is lie though...
Commander: ...?
Saratoga: N-nope, I didn't say anything! Come on Commander, we gotta pick up the speed!
Saratoga: The radar is speaking up a reaction!
Following the readings on the "Legendary Seal Radar", Saratoga and I continued on our journey.

3. Guardians of the Seal

Saratoga: Hmm Hmm, doesn't look like we made any mistakes while following the directions...

Following the reported sightings of the Seal, I think we have managed to get a good lead on the Seal's probable location.
Saratoga: Commander, we are close!
South Dakota: Commander, I am sorry but you have to stop here.
Massachusetts: Umm, uh... "We are the Guardians of the Seal."
Alabama: "If you want to pass through here, then you must first answer our question."
South Dakota: "We will not give the Seal's location to bad people who cannot answer this question."

It was like.... they were just reading a script halfheartedly...
Alabama: So, the question is: what animal group does seals belong to?

Options-

Commander: "The Seal family"
Saratoga: Commander, that's an excellent answer!

Commander: "The Cat family?"
Saratoga: Seals might have whiskers but they are not cats! They belong to the seal family!

Commander: "Save me Sara-sensei!"
Saratoga: Fufufu, the answer is "The Seal Family"!

Alabama: Correct. You may move along.

It seems like they'll let us pass now.
Saratoga: ... Pfft! I never imagined you girls would ever pull something like this!
Massachusetts: ... Why not? It's interesting.
South Dakota: Well, these girls were saying it would be fun. I am just tagging along.
Alabama: Were you not having fun, Aneki?
South Dakota: That's not what I meant. I feel good doing this as it's for a just cause.
Saratoga: Well well, there is nothing wrong with having fun! I bet the others would be surprised by this test!
Saratoga: Anyway, how are the preparations for that?
South Dakota: Ah, things are progressing smoothly.
Saratoga: Thank you~! You guys are really saving me here!

(What are they talking about...?)
Saratoga: Okay, Commander! Let's move on!

4. Seal Located!

...
Commander: "We nearly got it..."
Saratoga: Yup! This is the last place it was sighted!
Saratoga: All that's left is to give it our best and find the Seal!
Atlanta: Great job, San Diego! This is the location of the latest Seal sighting, it's surely here!
San Diego: Aren't I just amazing? Fufu, we'll be the first team to find that Seal~
Juneau: Commander, we are s-sorry for doing this!
San Juan: W-wait! We didn't find anything the last time we came here!
Saratoga: Uuuh, a rival appears before us as we reached the final barrier!

If both of our teams are going to the same place, then we just need to....
Saratoga: Wawaa! Don't pull on me so suddenly, Commander!
Atlanta: C-Commander?!
San Diego: Hahaha! You wanna race me to the end?
Saratoga: Stop! Stop, Commander! It's still too early!
San Juan: Saratoga! ... If that's how it's going, we need to do an emergency start!

Then, a large structure emerged suddenly from the ocean.
There were aquariums on it - filled with playful marine animals that the members of this event had rescued.

Commander: "...A stage?!"

And then, from the center of the stage, emerged none other than the Protagonist(?) of the show...

"That is....The Legendary Seal!"

5. The Legendary Seal

Although there were a few incidents along the way, Saratoga's charity concert concluded without a hitch.

Saratoga: Ehehe, what a good little seal~
The "Legendary Seal" – which in reality was just a regular seal – was giving little kisses to Saratoga's legs.
Saratoga: T-h-a-t-'s w-h-y you can't just protect this cute Seal like this for just a day! It's something you do every day and give your best!

Had I known that, I could've offered to help sooner...
Commander: "Offer your cooperation"

Saratoga: Commander, Thank You! Actually, I was going to ask for your help after we wraped up here~
Lexington: Saratoga, preparations for that are almost done.
Alabama: Do you want to see it with us, Commander?
Hmmm? There's more stuff going on today?
Saratoga: It's a bit late, but today is actually when the Sakura Empire and Dragon Empery celebrate the Tanabata and Qixi festivals.
Ning Hai: Nee-san will be preparing dishes for us today, please don't forget to come.
Ping Hai: Ping Hai, hungry...
Akashi: Fufufu, I prepared some special fireworks which won't scare our little guests in the aquariums, nya~
Baltimore: Saratoga... do you feel like we're forgetting something?
Aylwin: Hmm, what could that be...?
Dewey: The name for the little seal, desu!
Saratoga: Oh, right! We forgot to name this cute one!
Saratoga: Commander, do you have any good suggestions...?
It was decided that the name of the seal – the protagonist of the event prepared by Saratoga-chan and  beloved treasure of the sea that everyone cherishes – would be...
Saratoga: "Saratcchi"..."Sara-chan"! I like the sound of that!
Saratoga: Well then, Commander, I hope you will help Saratoga-chan to protect the blue seas..
Saratoga: and "Sara-chan", let's do our best from now on together!
