Konwaku (困惑)

Ryuuou orders Zero to obey Chuo, but he runs away had to be chased down. A tied-up Zero tells Chuo that a voice in his head told him to run, indicating that there's a potential flaw with the SCM. Sometime later, Zenichi escapes from the hospital and both Yuuga and Ryuuou receive a letter written in blood by someone identifying himself as a crazy person. Yuuga decides that he will challenge him, but Eia objects as she does not approve of Yuuga's approach to add as many slaves as possible. Eia takes Zushiohmaru and decides to end her working relationship. However, she is coerced into working for him again when he threatens to kill Ayaka by having her freeze in the bathtub to circumvent the rule that prohibits killing slaves. Eia reluctantly has Zushiohmaru challenge Ayaka to a duel to eat utensils. Zushiohmaru refuses to eat leading to him becoming Yuuga's slave through Ayaka. Not wanting to see Zushioumaru or Ayaka hurt any further, Eia agrees to work with Yuuga.
