"GAAAAAGGGGGHHHHHHHH!!!!"
Tanjiro drops to the ground where his blade meets the concrete floor too. Kokushibo's head lies to the side of his knees as Kokushibo thought, "A red blade... The same as Yoriichi..."
- Kokushibo's Memory (When he was a human) -
Both twins stood out on a path where the sun watched from above. Michikatsu asks, "What do you intend to do about the succession? There are no skilled warriors comparable to us. The prospects for succession to the breathing art are dismal. The perfected techniques will be out." Yoriichi turned to Michikatsu and said, "My Brother... We are not that great. We are merely one fragment of humankind's long, long history. At this moment, those who surpass our talents are uttering their first cries. They may come to reach the same place. There is no need to worry. We...may draw the curtain of life closed without unease at any time."Kokushibo (Narration): Does that not exhilarate you...Brother?"
Yoriichi continues, "Someday...the children now being born...will surpass us...and ascend...to even greater heights."
- Present Day -
Kokushibo's eyes widened while Tanjiro powered down to his base form. His blade reverts to its normal black colour and the mark disappears. Kokushibo thought, "Yoriichi...when you smiled, I couldn't help it...but always found it disturbing. And when we were talking about how there were no successors for the various breathing techniques...you suddenly started viewing with strange optimism...and you smiled. In my conceit, I believed...that only our generation was special. I felt sick with disgust and irritation. What did you find so amusing? Even after being cut down many times, the black-haired man did not give up. The human who's breathing was resemblant to that of a beast. The one whose speed even I had trouble keeping up with. That girl's sheer power was close to even that of a Hashira, despite having a small frame. But him... Kamado. His speed of growth is comparable to that of a demon. His strength even caught up to and even surpassed my own, but his stamina lacked. Most of them aren't users of Sun Breathing...but their strengths made up for that. What is so amusing about imagining a future? Just thinking about losing...makes me boil with rage. I will not lose again. Yes, even if he cuts my head off!"
As Tanjiro's vision begins to get blurry, he begins to spit out blood from his mouth and drops his blade. He uses both hands to keep himself up but uses his right hand to unclip some buttons on his uniform and looks at the amount of blood seething out from his wounds.
Krick!
Tanjiro heard to his right that Kokushibo had flexed his body so hard that it made some popping within the bones. Tanjiro slowly looked at him and saw that the blood stopped pouring from his neck. He quickly grabbed his blade and took a few steps back before falling to his knee. He was now dizzy and feeling heavy. He quickly shook his head and stood up. Everyone watched as Tanjiro powered up like before. Tanjiro said, "No matter how many times you regenerate, I'll still cut you up until there is nothing left!" Tanjiro goes in for the attack, slicing him vertically. Before Kokushibo could split in two, he regenerated even faster than before. Tanjiro unleashed many attacks that were rendered useless by Kokushibo's speed in regeneration. Tanjiro was about to stab Kokushibo but was grabbed by the neck and held in place as Kokushibo thought, "My body isn't falling apart. I'm not dead yet...they soon will be. I will overcome death by decapitation!"
Tanjiro saw Kokushibo regenerating his head and placed his hand in front of Kokushibo's half-regenerated face and fired a huge blast that allowed him to escape from Kokushibo's grip. Tanjiro coughed while waiting for the smoke to clear but heard a low growl from within the smoke. After it cleared, Tanjiro was shocked to see a monster. It had many horns growing from his body that were too grotesque to be recognized as his original state. Tanjiro held his chest from the pain before swinging his blade into the air and charging at Kokushibo.
