Tsuukonomoide (つうこんおもいで, Regretful Memories) is a Mujō of Shoribu Shinogeru, being brought to life by the centuries of regret the Taskmaster kept hidden deep within him. As such, Tsuukonomoide gains power by the regrets of others, using it to feed his powers of manipulation. Being a master manipulator, Tsuukonomoide can delve deep in the minds of his victims, using his masterful powers of persuasion to entice them with the promises of power in exchange for them killing those important to them, be it their family or village. But in the end, those promises are broken as the victim is killed by someone else he enticed, creating a deadly cycle of death and regrets. Centuries of regretful emotions has made him a very powerful entity, one that can strike fear into the hearts of his victims.
