He's the Duke's friend.
He's a doctor.
Actually, he's spy sent by the Church of Madonna.
In Yanggun's Miscellaneous Thoughts (15), when it updated July 5, 2008, Youngsoon Yang drew his prototype. His name is Keyton and he says he opens doors of all kinds of reality that can't be opened. Kitten is probably supposed to be spelled Keaton or Keyton.
In A Catnap (121), the Head Bishop says he just received a message from the archbishops and he's meeting the Duke soon, and they'll kill him all depends on the outcome of their negotiation. He asks at least let the boy live. The Head Bishop answers for the sake of keeping the balance between the Patron alliance, the boy shall live. So when he hears the Duke will die soon, he goes to him and shouts he's crazy bastard. Mayhen kisses the Duke's hand. The Duke is laughing, saying that he made a bet with Mayhen on the first thing he had say when he walk in, and the loser has to kiss the other's hand. He grabs the Duke by the collar and says he shouldn't make any deals with the church because they're gonna bad to do next. The Duke calls him to friend and says he's simply trying to end this long rivalry with other families, once and for all, and he doesn't want Gosan to live in a world of endless war. The Duke hugs and says if something ever happens to him, he want him to take care of Gosan. He cries and recalls. He thinks he's sorry for him, but he'll protect Gosan.
He goes to Mayhen and asks the Head Bishop's spaceship exploded and where's the Duke. Mayhen answers that the Duke is talking to the church right now and he gave a specific order not to allow anyone in the room. He thinks the Head Bishop's death will turn the church upside down and he did have something to do with his death. At this time, Mother Madonna shape which is a hallucination without a physical form is appears. Madonna says the barrier the White Police Guards set up must have blurred the image, and he couldn't expose himself, so he borrowed the image of her. Madonna says there's not a lot who know of his existence, and all he can tell him that he's a member of the church and he's as high ranking as an archbishop. Madonna, in fact, Ran says he knows who he's and what his mission to the Gosan family is all too well. He asks why should he believe him. Ran says because he'll kill him if he doesn't, and the Duke's death that the Head Bishop once mentioned but before the church get to that he must confess. Ran says he has the ability to calculate the causalities of the Universe eight, but there're times that his calculation is incorrect, and it happens when an unknown variable outside his domain jumps in, and the same thing happened this time some maniac twisted the time axis to enter into their universe from another, fortunately, it didn't affect the overall causality too much, but still some partial corrections have to be made so which is why he wanted to speak with him in person. Ran says in order to ensure the future of the Universe eight remains the same as it's preordained, he needs him to step up. Ran says he wants him to kill the Duke personally, and he'll get back to him with the execution date.
Ran prophesies the Duke will be brought to trial under the U.C.S. rules, meanwhile, his deal with the church will come to fruition and his family will be feared by the entire universe eight, and he must kill him before the verdict is delivered and cover it up as a suicide so that his son Gosan won't hold a grudge against them of this universe, and if by any chance he does hold them accountable, that will ruin them all, and he'll probably try to hide his identity forever for what his father's done.
At the night, the Duke is eating dinner, and another people don't eat. He recalls Madonna's words. He says he was thinking perhaps it'd be best if the Duke had let them clean up this mess and go on a trip to another planet until things quiet down a bit. The Duke says he just came back from Aorica. Mayhen reports the new messages. Mayhen reports the biggest issue was the Duke's meeting with the archbishops will soon take place as he wished. The Duke is relieved that he just hope that he'll make it till then. Mayhen reports the U.C.S. has announced that they'll soon dispatch an investigative team to get to the bottom of this incident, and for some reason, the nobles under their protection continue to ask them for more White Police Guards. The Duke sees the messages, and he says the nobles all made their requests after their little show on Aorica, so these imbeciles won't believe it until they see it for themselves. Mayhen reports the Count El also sent a message. The Duke says El's request had nothing to do with the Aorica incident, so he really like his attitude when he starting with the halidom from the church. The Duke orders that Mayhen should send more White Police Guards for El and no one else and ignore the rest.
