Kahaku

Kahaku (カハク) is the sixth successor of the Defense Corps and the first male successor of Hayase's will.

Appearance
Kahaku has short, black hair and brown eyes that strongly resemble Hayase's, a trait that all of her descendants share. He wears the same clothes that all leaders of The Defense Corps wear and he carries a spear on his back.

Personality
Kahaku, like all of his ancestors, is dedicated to his role in the Defense Corps and protecting Fushi. He blames himself for Fushi and the Defense Corps's current reputation as heretics in the Church's eyes. Although he is generally polite, Kahaku can be sarcastic to those he doesn't like (as seen in his first meeting with Prince Bon).

Towards Fushi, he is generally polite and willing to answer as many of Fushi's questions as he can, as well as wanting to be his friend instead of seducing him. However, after Fushi takes on Parona's form, he becomes flustered and nervous around the immortal, even attempting to propose for Fushi's hand in marriage. After this, he becomes more possessive of Fushi, wanting to protect fushi's humanity more than anything else. Despite this, he still holds Fushi well-being in high regard, supporting him when needed, giving him enough rest to recover and does his best to assist him whenever possible.

Background
He is the sixth successor in Hayase's line of descendants and the first male. He claims that his mother died before she could give birth to a girl, so they had to make do with him inheriting the knocker instead. When it was his time, he joins Fushi on his journey. Unlike his ancestors, though, he initially had no interest in seducing Fushi, and preferred if they were friends instead. Also differing from them is the fact that his knocker seems to have shrunk in size immensely compared to his previous descendants.

Plot
Kahaku joins Fushi in order to protect him from the Bennett church as well as giving the immortal some assistance on the battlefield. When Fushi becomes wanted by the church, Kahaku suggests that Fushi takes on a different form to avoid bounty hunters for a while. After shifting through a few of his female forms, Fushi ends up choosing Parona's form, who Kahaku immediately falls in love with.

After traveling for a bit, the group is immediately ambushed by Prince Bon's army, and Fushi is willing to surrender herself if it means Kahaku and the other Yanome clan will be spared. Bon agrees with this and allows Kahaku to be taken along as his prisoner. As Bon leads them to his father, Kahaku makes a note of the strange prince and when Bon warns that he should watch his tone since he would become king Kahaku merely states that would be fine, but Bon wouldn't be king in his mind. Bon storms off, declaring that he would tell his father when they get to the castle to which Kahaku muses at the prince's childish behavior.

Later on as Fushi and the gang were getting ready for the Knockers attack on the city, protecting him so that he can spread his roots, kohaku's arm gets out of countrol forcing kai and the others to take him into custody and tie him up on a chair. Shortly after kohaku's succesful escape he reunited with an exhausted Fushi who he tried to lend comfort to so as suggesting him food,tie and telling him he will always be there for him affectionately robbing his cheeks as he then ones again loses control of the knocker in his arm attacking Fushi resulting in the knocker stealing his memories which the resurrected March had to put a stop to. After finding the knocker which escaped onto ecko to seek protection from kohaku, knowing he wouldn't harm her due to Fushi's care for her he travelled to the Bennet church telling them that the immortal devil is still alive resulting in them preparing hot iron to one's again lock him up. The head priest questions his logic having thaught kohaku to be on Fushi's side jokingly questioning him on whether he had come here to die which kohaku smilingly confirmed jumping into the hot iron. The knocker tried his last stand for survival still holding on which kohaku cuts with his other arm resulting in him falling straight into the pot while smilingly and happily declaring his love for Fushi.

Skills
Using the Nokker in his arm, Kahaku can increase his left hand’s strength. He can stretch, extend, and manipulate his left arm/fingers without injury. His arm seems to have merged with the Nokker, as he is able to completely stretch his arm to throw his enemy; something his ancestors were unable to do.
