Summary

After seeing Earth become petrified, Byakuya began to plan how to revive all of civilization.

Plot Details

After seeing Earth become petrified, both Senku and Byakuya began investigating what exactly happened. Senku was able to think about the exact time that the phenomenon happened despite being turned to stone, while Byakuya was able to pinpoint the location where the petrification originated: South America. He suited up and prepared to head back to Earth, despite the protests of the crew and Shamil punching him in the stomach. 6 hours after petrification, the solo crew members touched down in the Pacific Ocean, missing by a great distance from their target, and upside down. Knowing that they would drown in a couple of hours, Byakuya decided to help them out despite Yakov's protests. Both he and Senku started counting time to measure how long since the petrification has started and for the latter to revive in the right season.

Lillian started to sing.

Meanwhile, down in the ocean, the trio desperately started to panic and tried to conserve oxygen to survive when, suddenly, Lillian started singing. Surprised and angered by the sudden reaction, Shamil saw that Byakuya had made it to Earth and was rescuing them via rowboat. They made their way to a seemingly remote island where Darya and Yakov were waiting for them. Once there, they decided to look around for any survivors and find one, only to find out that the person had been petrified, leaving everyone in shock and Connie distraught. Later that night, Byakuya found the Soyuz tool kit and decided to make dinner, with Connie finding food and Shamil joining her.

Shamil and Connie were getting married.

Days turned to weeks, weeks turned to years, and 3 years later, Connie and Shamil celebrated their wedding, with Byakuya throwing a party, with Yakov on drinks, and Lillian singing. However, in the middle of a song, she remembered her traumatic past and ran away, Byakuya chasing after her. Finding her by the coastline, she feared that all of the music would just fade away after the petrification. Byakuya assured her that it wouldn't, as long as Senku was out there alive, being so confident as to claim that he would succeed in life even if he weren't alive to see it. However, he lamented that Senku would need friends to succeed and decided to leave something for him.

But it was not to last. Sometime later, Connie was gravely ill and succumbed to pneumonia, this infection itself being an ancestor of the one that would nearly take Ruri's life thousands of years later. Soon, Shamil fell ill with it too and derided him for looking so glum, ironically flipping the tables on Byakuya. In his deathbed confession, he revealed that he always had fun since he went to space with him and saw him play around the space station. He never thought of starting a family until he met him and had kids with Connie. He revealed that the ramen Byakuya brought onboard was delicious, and he saw the petrification coincidentally at the same time; in his view, it was "hilarious." Darya and Yakov decided to go to the Japanese mainland in the small boat to find supplies in hopes of saving Shamil, but they were never heard from again. Shamil passed away soon after.

Byakuya thinking of the 100 Tales.

Another long time passed, and Byakuya and Lillian were the only survivors left. Having adopted and raised the children on their own, the couple were at the beach, trying to write on the sand, but Byakuya had trouble authoring any stories in English. Lillian suggested he write them in Japanese, and her desire to learn it had Byakuya pondering what to write. He decided to write 100 stories about everything on Earth there was to find, and the first one was to find Senku in Japan. He finished them all but experienced another tragedy as Lillian died in his arms soon after he was finished writing them.

Senku visiting Byakuya's grave.

3700 years later, Senku is revived. After all he went through in the previous years, from reviving Taiju and Yuzuriha to fleeing Tsukasa, his ambitious plan around science, and recently, his indictment as chief of the village, he has a lot to take in. Ruri takes him to the forest to privately share Byakuya's last message, leaving the party and the gang. Senku deduces that Chrome took an interest in his late father's stories due to his own experiments with science, and the old man helped him in some way, despite the village's ousting of them both. Ruri then shows Senku the village cemetery, and he saw a mountain of graves circling to the top, with Byakuya's on top. Having told the 100^th tale as known to the village through history, Ruri tells Senku a last part of it, which she's kept to herself all this time, a message from his father. Widowed and lone survivor, he fulfills his promise to Senku in the form of people he will befriend on his journey to make the world even better than it was before (in a way, the village). Suddenly, Senku sees a vision of his father telling him that he will succeed in his goal and make it better than he ever could. After shedding some tears, he returns to the village, where he grabs Gen and interrogates him. Gen reveals that Tsukasa and his army are coming to destroy Ishigami Village, much to Kohaku and Chrome's horror but to Senku's delight, as he finally has a chance to show Tsukasa his scientific accomplishments.
