1st and 2nd year μ's went back home after Nico conceded. Elichika cleaned up the broken pitcher before heading back home. Nozomi decided to stay at Nico's house.

Nico: "I want to try to see if Aqours can help us fix the filter even if it wasn't my idea."

Nozomi: "Nicochi, there is no turning back on what you just said."

Nico: "Right, I did not have any tricks related to this."

Nozomi: "Will you go, or are you going to stay with your family?"

Nico: "I will go with my family. If my family goes then Aqours does not need to supervise us."

Nozomi: "Nicochi, have you figured how we are going there?"

Nico: "No, I have no experience with planning trips, and I will never need to learn."

Nozomi and Nico's mother plan the trip to Aqours. While Nico plays with her 3 siblings.

Nico's mother: "So, who do you think we should go with on the trip?"

Nozomi: "I am thinking that the 1st years should go because they get along very well with Nico. Nico and Maki are the closest friends. Maki, Rin, and Hanayo spend time together the most. I know that Umi has an archery tournament nearby, so I do not think that she will be able to come."

Nico's mother: "Have you contacted Aquors about this yet?"

Nozomi gave Nico's mother Kanan's phone number. After a while, they hung up.

Nico's mother: "Kanan says that we can come to them this weekend. She said that I will be in charge of the key and equipment. We can bring anyone with us as long as they are my children or in μ's. However, Kanan says that she would not be able to reserve a time after this weekend."

Nozomi: "Well, it seems like me and Elichika cannot go because we promised to go to Umi's archery tournament."

The next day, Nico shows 1st year μ's the secret recording that she did on Nozomi's conversation with Nico's mother.

Rin: "So you really did care about the trip?"

Nico: "No, I only wanted to record because to show my espionage skills!"

Maki: "This time, Nico will be the one to dive down there."

Nico froze and stared.

Hanayo: "Nico, what are you thinking?"

Nico( says while smiling): "How about we visit Tokyo while Aqours do all the work?"

Hanayo: "But, don't you want to meet Aqours just like you want to meet A-rise?"

Rin: "And, we can punish you at Aqours by making you do the diving!"

Nico: "Okay, okay. I will go to Aqours. But, don't blame me if I suck."

Later that night, Nico's mother, her 3 siblings, and Nozomi were sleeping over at Nico's house.

Nozomi: "μ's has decided that Nico would be the one that dives down."

Cocoa: "Nozomi, would you stay at our house while Nico is gone?"

Nozomi: "Sure! Although, I won't be here much during the day."

Nico: "I don't think that I would be good at diving."

Cocoro: "Don't worry! We will be cheering you throughout."

Cotaro: "Mommy said that we won't meet Aqours!"

Nico: "That means that we should visit Tokyo, instead!"

Cocoro: "We still can visit Kanan's diving shop"

Cocoa: "I think I would like the beach more"

Cotaro: "Tokyo would be too noisy!"

Nozomi: "Nicochi, Maki would surely snitch on you if you try to defect to Tokyo."

Nico: "Wow, you girls don't have any taste!"

Nozomi convinces Nico's mother to allow her, Elichika, Alisa, and Umi to stay at Nico's house without supervision during the weekend.

Nozomi: "Umi's archery tournament is closer to your house than any other."

Nico's mother: "Would Kotori and Honoka stay with you girls, too?"

Nozomi: "No, their grades are too bad to do that."

Nico's mother: "Are they going to come with us to Aqours?"

Nozomi: "Yes, but they are going to travel by plane because Kotori got herself a coupon for missing her trip to America."

On Friday afternoon, Nico's mother drives with Nico, Maki, Rin, Hanayo, Cotaro, Cocoa, and Cocoro. During the trip, Maki sits in the co-driver's seat listening to music and looking outside the whole time. Nico plays with her sibling very loudly. Hanayo and Rin would sometimes join in. Surprisingly, they made it quicker than Honoka and Kotori.

Rin: "Cheer up, Maki! We get to explore Kanan's shop in the off hours. Imagine how important we are to be taken as customers even during non-operational hours!"

Nico: " I am about to think that there are ghosts in there because of how dark it is."

Maki: "Stop lying! Why would you say that for this particular building? There were infinitely different times you could have said it, and you choose this time."

Nico's mother opens the front door with "do not replicate" keys.

Nico's mother: "Yep, this is the place."
Rin: "Wow, Aqours really did leave this place."

Hanayo: " I heard that there are arcades down in the basement."

Nico's mother: "You can't tell anyone that! Who did you learn it from?"

Hanayo: "But, I was just guessing."

They explore the diving shop for a while.

Hanayo: "I wonder why Kotori, Honoka and Yukiho are still not here."

Nico's mother: "Yukiho is staying at home because she doesn't like to hang out with Honoka. Honoka and Kotori have just passed the airport security. However they decided to just go to the ferris wheel instead."

Nico: "What? Not fair."

Maki: "Nico, did you really just say that in front of your mother?"

Nico's mother: "Don't worry Nico was just kidding."

At that moment, Nico knew that if she did object against going to dive, not only would her mother force her, but also, her mother would be so shocked that Nico might get excommunicated.

Nico: "Yes, I was just kidding. Okay, let us go on Mari's yacht to let me dive."

Hanayo: "I know how to operate a yacht. I learned it online, diligently."

Nico quickly runs away before Maki grabs out the filter. At first, no one noticed, but then, Rin shouted, "Look, it is brown!" Maki almost drops the thing.

Maki: "What, I thought it was blue!"

Rin and Hanayo: "Well, I did not remember what color it is supposed to be."

Maki: "I guess we'll just go with it because there is just one person who suspects."

Nico, Maki, Hanayo, Rin, Cotaro, Cocoro and Cocoa went on the yacht. The sky was sunny and clouds were sparse. They went around one hundred meters offshore before Hanayo stopped.

Maki: "Nico, take off 'your' whatever that is and put these on."

Nico: "We are supposed to have fun. Right? Let's have fun until my mud mask just falls off."

Maki: "We cannot wait that long or the boat will run out of gas!"

Nico: "Go eat mud!"

Maki: "Okay"

Maki tackles Nico to the bright white wall of the yacht. Nico spits, farts, sneezes, and bites Maki's breasts.

Maki: "That won't hurt me because I know that you are cute and sexy."

They wrestle for 20 minutes. Nico's siblings were watching the whole time. The graphic content made them in awe and curious. Nico loses from tiredness. Maki puts the scuba gear onto Nico.

Maki: "Don't blame me for messing up whatever that's on your face."

Nico: "Okay, don't be telling anyone what happened here."

Maki ties a string around Nico.

Nico: "Hey, what are you doing?"

Maki: "I am trying to make sure that you don't swim away and escape."

Nico realizes that she could retire from being a diver by misconduct while diving. Maki hands her a barometer.

Maki: "Now, the first time you dive. You must not go above one and a half bars. And, you must hold the barometer in such a way that it is visible to all of us.

Nico: "I get it"

Maki: "Hanayo and Rin come hold the string with me."

Nico dives down. Cotaro, Cocoa, Cocoro watch from the slides of the yacht. Nico's barometer starts displaying two bars. Rin, Maki, and Hanayo pull on Nico. Nico resurfaces, and all of her crewmates start berating on her.

Nico: "What is one and a half again?"

Maki: "Get out of the water!"

Cotaro: "Ooo, I will tell mommy!"

Nico gets out of the water and undresses.

Rin: "Nico, put that back on!"

Cocoa: "Don't worry, we have all seen Nico naked before."

Nico: "Oh, I thought this was part of the diving gear. Diving is really hard for me. Hahahaha!"

Cocoro: "I think we should tie Nico up to make her calm like me."

Hanayo: "Can I try diving?"

Hanayo gets an affirmation. Nico gets tied on to the deck. Hanayo did not have to wear the string, but she still is required to carry the barometer.

Maki: "Hanayo, you can dive up to three bars this time. No one is allowed to dive above three bars."

Hanayo dives a couple of times. Nico did not get to see any of it because she was tied down to the deck. Maki assembles the water filter and pitcher. Nico complains to Maki about not being able to see the water and Hanayo getting to dive deep.

Rin: "Are you sure that the insides below the water filter are water-tight?"

Maki: "Yes. The pitcher is thick and made of steel, and the filter would be pushed by the water pressure to create the water tightness around the water filter. The only way water can get in would be throught the filter holes."

Rin signals Hanayo to come up. Nico's siblings were surprised and talked about the big metallic water pitcher.

Hanayo: "I wonder why Kanan even has something like this."

Nico: "Excellent idea! We should stop diving and go ask Kanan about this."

Maki: "We are not going to stop just because of this!"

Rin: "We forgot to ask about the water pitcher earlier because we thought that the fact that the water pitcher is strong is good enough."

Hanayo dives into the water. At two and a half bars, Hanayo hears a loud pop from the water pitcher. She continues and stays at two and nine tenths of a bar for ten minutes. Then, she resurfaces.

Maki: "Hanayo how was it?"

Hanayo: "I think that we should make it a surprise. Let us keep it closed until the next morning."

Rin: "That's a good idea. We have all of tomorrow to try again!"

Maki unties Nico. Nico's siblings praise Nico for changing her behavior. For two hours, Hanayo and Rin learn diving while Nico and her siblings were only allowed to snorkel and swim. Afterwards, Hanayo steers the yacht to shore.

Nico: "We really need to celebrate by playing in the sand with all of us."

Maki; "Luckily, none of us have homework because it is almost the end of the school year!"

Rin: "I really want to tackle Hanayo after seeing Nico and Maki Having fun!"

Hanayo: "The sand might be too sticky and dirty. But, everywhere else is too hard to fall on."

Nico: "We can tackle each other in mud puddles! There are many other activities we can do in the mud. Like racing, mud volleyball, and water fights."

1st year μ's, Nico, Nico's mother, and Nico's siblings all went to play in the mud puddles that were created by Kanan's water hose for four hours.
