==Plot==
Youto, Tsukushi, Mai, and Azusa play together as they have done over the days following the visit to the Azuki household.
They are playing hide and seek in the middle of the residential district, with Youto as the seeker. After counting, he looks up into the air and screams the first word coming to mind: "Breasts!" Tsukushi at a loss for words as she hid behind a tree, Mai raises her fist, and Azuki Azusa turns around towards Youto with a baffled expression as she runs down the street.
An onee-san walking by stops to look at him in shock. Returning her a nod, Youto opens his arms and legs in a grand gesture, and screams the word once again. She looks down at Youto with pity and rubs him on the head, and Youto continues his antics. Eventually, the peaceful residential district is filled with laughter.
This is until Tsukasa dashes out of the courtyard and drags him back inside. Surprisingly, the onee-san, who Youto nicknames "Breasts Onee-san," was on her way to visit the Tsutsukakushi household as well.
When the girls call for Youto to resume the game, he suddenly finds Tsukiko, who he hasn't paid much mind to for a few days, clinging onto him. After being given a snack, she mutters "potty...", apparently in search of the toilet. As Youto takes her down the hallway towards the washroom, he hears fragments of the conversation between Oppai Onee-san and Tsukasa, something about "returning" and "daughter's consent." Walking past the tatami room, Youto spots the hedgehog outfit, reminding him of Tsukasa's illness, which he must find a way to cure.
Before they reach the washroom however, Tsukiko suddenly sighs, muttering "...No more...", before she suddenly slaps Youto across the face. Growing teary-eyed, Youto questions what he has done to deserve such treatment, but Tsukiko confronts her, accusing him of "not doing anything." "It seems like you’ve gotten quite used to this world. I would have loved for you to realize it yourself, but I cannot wait any longer." She speaks with eloquence unbefitting of her age, urging Youto to return to his senses.
She reveals that she has always retained her adult consciousness since they were transported to this timeline, just like Youto. However, she acted like a child so history wouldn't be changed. She warns Youto that he has done too many outrageous things, fearing that his actions might destroy the future.
However, Youto questions Tsukiko's own behavior as well, including licking him, pushing him down, and crawling onto him. Tsukiko grows silent at this, before changing her story and insisting that she only just regained her adult consciousness.
Tsukiko tells Youto that the visitor today is the representative for their relatives in Italy, acting as a stand-in to negotiate custody. She requests Youto's help regarding the issue because there is too much at stake for her to be taken to another country. Youto feels that there is no need for concern, as in the future they know, the Tsutsukakushi sisters never went back to Italy.
However, Tsukiko explains her anxiety over the butterfly effect. For example, in the original timeline, Tsukushi developed an extremely close relationship with Tsukiko because they lived together alone, but as a result of Youto's actions, she now has friends her age. Given this, she might not become obsessed with the idea of marrying her sister, and their relationship might never break up. If that ends up the case, Tsukiko and Youto likely wouldn't meet each other at the hill with the cat statue at all.
Slowly realizing the implications, Youto comes to understand why Tsukiko was angry. However, the possibility to reshape the future only fills him with excitement. He encourages Tsukiko to move forward, arguing that they traveled to this timeline for this exact purpose, and guaranteeing her that they will not lose each other no matter what.
In the negotiation, Tsukasa is currently struggling to assert her position. Devising a plan with Tsukiko, Youto barges in, jumping around and demanding food to break the tension. He then points at Tsukiko, announcing that she wet herself. She picks up Tsukiko and lifts up her skirt, showing the area between her legs to Tsukasa.
Their conversation interrupted, Breasts Onee-san stands up to leave, saying she'll come back another time. After taking care of Tsukiko in the washroom, Tsukasa tells them to buy something at the convenience store before sneaking into the futon, the negotiations clearly taking a toll on her.
Tsukiko questions their next steps, worried that nothing will change at this rate. Youto however is confident with his plan, announcing that she can "leave everything to him," prompting Tsukiko to remind him about his phrasing. Youto immediately corrects himself, instead declaring that he'll borrow everyone's strength this time.
