Senjuro at one point felt like a failure. His brother was a Demon Slayer, a hashira, keeping the family tradition going, and he was supposed to be the successor. His dreams were crushed by his father, Shinjuro, who hit him, discouraged him. When he got the news that his brother had died he was devastated, the family tradition was broken. However, Tanjiro encouraged him, lightened his mood, and despite breaking the tradition Senjuro wanted to help people in other ways. He didn't need to slay demons to help people. He knew his big brother Kyojuro would forgive him for his choices.

He dusted the outside of his place, decided to visit the people more during the day. Everything was looking good for him for once. He figured that his big brother would forgive him for his choices. His father even seemed more quiet, and he had also been trying to restore the contents of the book his father ripped for Tanjiro to possibly help.

He was currently in the shade under a tree, studying the book, trying to find bits and pieces on the ripped pages. Upon looking closely at the book, he thought he saw movement on the edge of his vision. He looked up from the book and saw you walking through here. It's been a while since he talked to someone new, so he decided to try it.

"Hey, um nice to meet you!" You turned to meet him. "I'm Senjuro Rengoku." Maybe you'd know something about the book too, and possibly become his new friend.
