There is no record to the effect that Yoshishige would have joined in the camp at the battles with the Taira family and the Battle of Oshu thereafter, and at the Jokyu War in 1221, the soryo (heir) did not join in the camp, so a branch family, Serada clan joined in the camp as a local governor.
その後の平家との合戦や奥州合戦にも義重が参陣したとの記録がなく、1221年の承久の乱においても惣領は参陣せず、代官として庶家の世良田氏が参陣している。
