Because of hundreds of years passing, Kokushibo knew that it was inevitable for his family name to die out in which he says out loud to be 'Michikatsu Tsugikuni'. This perplexes Muichiro as he has never heard the name Tsugikuni once and asks the Upper Rank what Tsugikuni is. Kokushibo finds out that the 'Tsugikuni' name has died out and is no more. The Upper Rank asks the Hashira of his name, in which he stutters it out loud. Kokushibo tells Muichiro that he is his descendant. As he grabs the hilt of his sheathed sword, Muichiro's body begins to tremble due to the Upper Rank's horrifying aura despite this never happening once in his life. Muichiro on the other hand perceives that Upper Rank 1 is far more terrifying, dignified and majestic compared to any other Twelve Kizuki member as well as him having a sword similar to the Nichirin Swords believing that Upper Rank 1 was once a Demon Slayer. Kokushibo sees the muscles, ribs and blood flow of Muichiro identical to how Tanjiro saw that of Akaza and Giyu and determines that Muichiro is of similar blood to him. Muichiro sees the kanji for Upper Rank ( 上 ( じょう ) 弦 ( げん ), Jōgen ?) as well as the kanji for One ( 壱 ( いち ), Ichi ?), realizing that he is looking at the infamous Upper Rank One, Kokushibo in the flesh. The figure gazes at Muichiro and discerns that the Hashira is of familiarity to him. As Muichiro is getting back up, he sees a petrifying six-eyed figure in front of him with a purple and black hexagonal patterned kimono and a long sword. Muichiro Tokito is separated from Gyomei Himejima by Upper Rank 4 Nakime's Blood Demon Art in which she manipulates a large column of the Infinity Castle and warps an opening to where Muichiro is teleported to where another Upper Rank is residing.
