Senku had arrived at the Ishigami village accompanied by Kohaku, realizing that the village would be a great place to start his plan.
He already knew the most influential people in the village, Magma, the leader, Ruri, Kohaku's sister, Kohaku, Chrome and Suika.
He, Kohaku and Chrome had begun to build their "Scientific Kingdom" in order to defeat Tsukasa. Today he had reviewed with Chrome the stones that Chrome had collected.
Night had fallen and Chrome was sleeping, but Senku couldn't. Instead of sleeping, he thought about how to win over the people.
He was inside a sleeping bag, looking at the ceiling, until he heard a branch break outside the hut, which caught his attention.
The thought that it was Tsukasa or some enemy crossed his mind, without making noise, so as not to wake Chrome or alert the thing causing the noise, his movements approached the door, lifting the curtain to look around a corner.
Looking outside he saw a boy/girl walking, that person seemed lost in thought, but that was not what surprised Senku, it was the appearance of that person.
That person was identical to his father, Byakuya, the same hair color, the same eyes, even the way of walking in circles reminded him of Byakuya.
He knew that the people in the village were descendants of his father and other people, but he had never seen anyone with his father's genes, obviously it caught his attention.
He discreetly left the hut, going down the stairs without making any noise, he resumed his serious demeanor as he watched that person walk around in circles while thinking.
—"Hey, what are you doing here?"
He said, looking at the person with a serious face, a hint of curiosity as he looked at you.
