Summary
Weather Report and Narciso Anasui are outside of the hospital. While Weather feels the presence of Enrico Pucci, Jolyne and another kin, he is unable to determine their precise position.

In the sinkhole, Jolyne and Ermes are trapped in the memory of a plane due to crash, which has been summoned by Donatello Versus's Under World. Jolyne decides to open the door on the side of the plane to reach the Stand user. Giving another string to Ermes, she opens the door and jumps out to strike Donatello with Stone Free. However, Stone Free only hits glass. It turns out Jolyne is trapped in another memory, the memory of a jet fighter which has been hit and will also crash soon. Humourously, the pilot asks Jolyne to check out the damage to the plane. Jolyne tries to climb back, but the string snaps and the two planes pull away from each other. Jolyne then projects her string and snatch the phone of a policeman who was looking over the sinkhole to contact her allies. Pucci explains all of this to Donatello, who's losing his cool over being treated like an incapable.

A flashback details Donatello Versus's flashback. Donatello doesn't know who his biological father was. During his childhood, he was seemingly the unfavorite, his parents doting on his half-sisters. Donatello fled his home at the age of 13. One day, a pair of precious baseball cleats fell on him by accident. Donatello tried them on but was soon arrested by the police. The court harshly judged he was the culprit and refused to believe his testominy and thus was sent to a detention centre. The real culprit was caught four months later but Donatello was still traumatized by his stay in prison. He recalls accidentally tripping on a hole and cutting himself on a hidden knife. Not only was he beaten by another inmate who had hidden said knife, he also witnessed strange occurrences like worms bursting out of his wounds, and skeletons hidden in the walls. Donatello lived a bitter existence until now, but after acquiring his power, Donatello starts conspiring against Pucci and plans on reaching Heaven by himself. Donatello decides to sneakily dig out a memory of Pucci and steals the DISC containing Weather Report's memory.

In the jet fighter, Jolyne tries to call Emporio. She asks how to activate the ejection seat but the pilot says that they are unusable since he didn't get to use his seat either before crashing. When Emporio finally answers, Jolyne hastily tells him the situation, which confuses him. There is less than one minute left to the passenger plane crash. However, Jolyne makes the jet fighter crash into the plane, using the technicalities of Under World's memories to join with Ermes. Meanwhile, Emporio is looking at articles mentioning the crash and tells her where two survivors were seating. Jolyne and Ermes run to the back of the plane, pursued by Under World who wants to destroy the seats. Jolyne manages to trap Under World against two walls. The duo reaches the seat, but it turns out Under World has taken three sick and injured children and let them fall into the seats. Donatello intends to force the heroes into a sadistic choice to make her hesitate and at worst, weaken her spirit with guilt. The duo is facing a nearly impossible dilemma as the plane finally crashes and a great ball of flame engulfs everything.

Donatello and Pucci see the plane explode. Pucci asks Donatello if he doesn't feel guilty, to which Donatello rejects the blame of the children's fate on Jolyne. Suddenly, Pucci sees the body of one of the survivors which has been partially duplicated by Kiss and protected one of the children. The two remaining children were kept safe on the seats, while Ermes hid between the copies of the second surviving passenger, and Jolyne unraveled herself to hide inside of Ermes. Thus, everyone was able to survive the crash. Jolyne sneakily ties Donatello by the legs before she regathers herself, shocking Donatello. He summons Under World but Stone Free pummels him and hangs him on a rock. While Jolyne and Ermes are eager to confront the priest, Pucci calmly laments Donatello's fate to lose. In anger, Donatello sends Under World to the surface. Pucci notices the theft of the DISC and warns Donatello of the danger he's putting everyone through. However, Donatello is taken by ambition and anger. Donatello warns Jolyne that Weather is actually not on her side and that his power was sealed because it was extremely dangerous. Suddenly, the hole is filled with rainbows. On the surface, Under World has just inserted the DISC into Weather, who turns into a violent spiteful man.
