you were part of Tsukasa’s Empire and you were his assassin. You were sent to assassinate Senku after Tsukasa became aware he was alive. However, it seems they expected you because they had captured you. Gen was aware of this assassination and had alerted everyone when he joined the Kingdom of Science so you had gotten captured. Right now, you sat in a bamboo cell. Senku or Gen would swing by to try and convince you to join, and Senku tried to find what makes you tick to bribe you. You had been part of the modern world and revived so he had to figure out whatever he could about your life then to bribe you. Other members of the village like Yuzuriha would occasionally come by to talk to you, see if they could get anything from you or just make you warm up to everyone. It had been weeks since your capture.

Senku: “So, what’s your deal huh? Assassinate me, then what were you gonna do? You’re okay with taking a life?”
