| THIS IS A MANGA ONLY DISCUSSION POST. DO NOT DISCUSS ANYTHING BEYOND THIS CHAPTER. ---------------------------------------- So it seems Koku and Demon hunter who met Sumiyoshi(Tanjirou ancestor) at chapter 99 are twin brothers with Koku being older. Extremely old Sunbro owning Koku as Demon. Sunbro prime couldn t kill Muzan. Prime Sunbro and Muzan>>>>>>>Um1 koku It sad how Koku is fallen and Sunbro feeling guilty of failing to save his brother.As it probably one of his reasons of his guilt when he talk to Sumiyoshi. Awesome more I love koku. More of this flasblack interest me. 10 out of 10 rating |

| Wait what, Genya has now a Blood Demon Art? So epic! It’s funny how every demon slayer has some demon’s traits (with the breathing techniques and now this with Genya) and as the manga goes on this vibe keeps getting stronger each chapter. While the demons “turn back” to humans in the end. Lol, so well done. Anyway, we are finally getting probably the most wanted backstory in the whole manga. The old guy looks like the one Tanjirou saw in the deam (chapter 99), but he was younger tho. Or I might just be wrong. This is raising even more questions. |

Koku and him is brother and Koku still can't beat him even if he an old man then. Koku only live cause the brother die from old age. |
| wow so Upper Moon One have a twin brother and that person is the ancestor of Tanjiro the first Breath of the Sun user so its safe to say that Upper Moon One really only knows this Breath of the Moon technique and not the Breath of the Sun that only a genius can do like his brother did and Genya is really a demon now lol he even got a Blood Demon Art wtf |
| it was pretty obvious that kokushibo was the brother of the one in tanjiro dream since it's said that muichiro is a descendant to sun user. koku said that muichiro is his descendant. kokushibo was nostalgic about his brother when he sees sanemi and genya. sun user was guilty of something in the dream. btw great chapter one of the best. so maybe sun user passed the kagura dance and the earrings to sumiyoshi,tanjiro's ancestor. |

| It refreshing to finally confirm Michikatsu Tsugikuni(Kokushibou) and Yoriichi Tsugikuni(Breath of the sun) are brothers. This two brothers are unstoppable It must been major upset Muzan escape this two. Michikatsu and Yoriichi could have easily Squash Muzan If they use Breath of the moon and Breath of the sun. I got feeling Michikatsu betray Demon hunters, His brother and help Muzan escape for unknown reasons. More of Koku backstory and motivations. Would be nice Yoriichi make Muzan drop in his kness. I fail too see how Michikatsu and Yoriichi fail too kill Muzan if they work together. |

| Upper Moon One will get angry and power up in the next chapter i bet since he remembers his envy and anger/frustration about his genius brother the original Breath of the Sun user i can see the Mist Pillar gonna die in the next chapter or maybe even the Stone Pillar will die too |

| it's flashback time, that little brother sadness... strong envy tho. |
 "If taking responsibility for a mistake that cannot be undone means death, it's not that hard to die. At least, not as hard as to live on." |
| Yoriichi basically do one last power move again his brother then die. Koku could never get closer knowing he will always be 2nd best. |
| KNEW IT, UM1 was related to demon slayer corps somehow. Looks like it’s not through first breath of sun user, but still very interesting. While sad, cool how he literally died of old age and exhaustion before finishing his brother off, that just shows his power |
 |
| Well, sure came as a surprise that breath of the moon and breath of the sun's users were brothers for me though because always thought that he's the one who tanjiro saw in his dream. |
| wow, UM1 mustve been really frustrated by that entire ordeal |

I fail too see how Michikatsu and Yoriichi fail too kill Muzan if they work together. Muzan probably tempted Kokushibou with the power to surpass his brother if he accepted his blood and became a demon. This would have been an extremely alluring proposition for Kokushibou since it seems like he always lived in his brother’s shadow. Of course, now we know exactly how that turned out for him. |
| since we get to see his twin brother, I am well intrested on how he became a demon |
| That younger brother was ridiculously strong despite being 80+ years old. |
 |
| Kokushibou's backstory is great, I really like it. Can't wait to see more of it, 'cause as for now we only got a glimpse of what was his main problem before turning into demon. Visuals when he fought with his older brother who got old (yeah, obviously xD ) but remained insanely strong, was amazing, just as its whole setting. About demons, I'm getting worried about Genya. His Blood Demon Art looked powerful, and he devoured a lot of cells from the strongest Upper Moon. Is it possible he won't be able to return human and without anybody to accept his transformation (Muzan had to accept all demons turned temporary by Upper Moons) he will just die as a half-demon? :( |

| It's similar. It turned out that the person who met his father Tanjirou turned out to be his twin brother Upper Moon 2 ... |
| Holy crap that ending.... his twin brother died of old age in the middle of a fight... jesus |
 |
| It is possible that Tanjirou's ancient sword was originally Yoriichi's! That's just my theory though.😯 |
 She got him back. If you understand the characters well enough, you'd know she did! |
| Flashback again, flashback is a sign for the devil he'll dead soon. They can make it. I though that grandpa is the first devil hunter with a god technique. |
| Woah Genya used Blood Demon Technique?? Yoriichi and UM1 are brothers but old age Yoriichi clapped Kokushibou easily only for old age to take him away...So is Yoriichi an ancestor of Tanjirou? |
 |
| memories of 400 years ago and his twin brother!!!! kekeke |
