Holder of the Duty bead. Sosuke also survived the fiery destruction of Otsuka Village. He did not have relatives and was raised with Shino and Hamaji as if they were siblings. He has a peony-shaped birthmark on the back of his neck. Ever since the accident that happened 5 years ago, he has an ability to transform into the dog Yoshiro.
Sousuke has a very gentle and caring personality, and is more like a big-brother figure towards the childish Shino.
