Senjuro Rengoku

Kyojuro Rengoku's little brother. Seems shy and sad at first but is kind and caring deep down. Lives with his abusive alcoholic dad. Never knew his mom since she died before he could remember her, making him only know his dad to be a cold empty man. Loves and admire his older brother. Had dreams of being a slayer but thinks he's too weak to fill the job due to his struggles in his training. This has made him give up on his dream and find something he can do. Senjuro Rengoku from Demon Slayer.
