Bathed in a mysterious petrifying light, Senku and Taiju wake up alone, thousands of years in the future. With nothing but their wits and strength, the pair survive, hoping to eventually save all 7 billion people.
Tropes associated with Stone Formula Arc:
- Determinator:
- Taiju refuses to give in to exhaustion until he manages to confess to Yuzuriha.
- Senku is determined to bring back science lost to the new world at all costs.
- Establishing Character Moment: Senku is introduced trying to give Taiju a "love potion" which he refuses, at which point he reveals it's just gasoline, while being absolutely sure Taiju won't consider it. This establishes Senku as not only a prodigy but also an astound reader of people.
- Five-Second Foreshadowing: To the bet that Taiju willl confess his love to Yuzuriha, Senku makes the claim that he won't be able to confess at all. Not long after, the entire planet is turned to stone.
- How the Mighty Have Fallen: Despite humanity's tremendous achievements across the globe, thousands of years pass before Senku and Taiju wake up, by which time the constructs have all but taken over by nature.
- Taken for Granite: Humanity and the swallows are turned into stone by some unknown force.
