6 YEARS LATER
At the butterfly mansion Senjuro Rengoku (The new flame hashira,and Kyojuro’s kid brother [age 20]) was honing his flame breathing skills when he heard a crashing noise from inside the mansion. (I wonder what that could be.) Senjuro thought he went to find the disturbance. When he turned 15, Senjuro began training as Tanjiro’s Tsuguko. Even though Senjuro never had the talent of his older brother, Tanjiro never gave up on him and after 4 and a half years of sleepless nights and hard work. Senjuro was appointed to the position as Flame hashira. Thanks to Tanjiro’s training, Senjuro mastered every flame breathing form and created his own form. Flame breathing 10th form, molten eruption. This created a fast strike with lava slashes on the sides creating a triple attack.
(Master Tanjiro, you always did believe I could become a hashira with just hard work and no talent.) Senjuro thought as he saw the moon hashira, Nezuko running towards the mansion. “Senjuro!” Nezuko shouted with the boy looking confused as ever seeing his superior run around like an airhead. “Lady Kamado what’s wrong?” Senjuro asked.
Nezuko started panting hard. “Kanao went to labor this morning and I was busy hunting demons. Is she okay? Was Tanjiro with her? Is the baby healthy? I heard she was sent here to be treated and I came as fast as I could. I really hope Kanao’s okay. I know having a child is rough on the body, but I can’t relate because I can’t have kids. No literally Shinobu showed that I didn’t have the proper genetics to have children.” Nezuko began to rant until Senjuro stopped her.
“Have you tried going inside the mansion?” Senjuro asked. Nezuko looked dumbfounded and entered the mansion.
“Aoi where’s-.” Nezuko gets interrupted by Aoi. “She’s fine Nezuko, I’ll lead you to them.” As they approached Kanao’s room. “Hi Nezuko.” Tanjiro waved as Nezuko saw her niece and nephew for the first time. “They're so cuteeee. I’m so proud of you Kanao. I know it must have hurt a lot to bring them here.” Nezuko said as she cried over her sister in law. “It wasn’t that bad Nezuko, It wasn’t as bad as being stabbed or anything.” Kanao said light heartedly. “Sorry for making you worry Nezuko.” Tanjiro said.
“Don’t apologize you were the ones who became parents today and I wasn’t with you two to help.” Nezuko said while hugging Tanjiro.
“Senjuro.” The triplets called. Over the past years the triplets have developed a crush on Senjuro and have agreed to share him with each other. (If big brother saw me now he’d be comparing me to Tengen and his 3 wives.) Senjuro thought as the Kocho triplets squeezed him from all sides. Senjuro liked having them around him but at times they could be overbearing. When his father died of alcoholism he joined the demon slayers and met the triplets. They always supported his dream of becoming the next flame hashira. He already unlocked his mark(Sun shaped marks across his eyes.) which gave him a huge boost in power.
“Looks like you have experienced the first step of the flashy lifestyle.” Tengen said as he passed Senjuro.
Soon Murichrio was able to calm down his wife Nezuko, (More on that later). “Congrats on the kid Kamaprijo.” Inosuke said. As the years passed Inosuke developed a more polite personality as he developed a crush for Aoi at 17 and tried his best to become a better person for her. He still is an airhead and always is reckless in battle. “What would you all do without me?” Aoi asked jokingly.
Zenist was next to greet the new family with his wife Yui. At 18 Zenistu gave up on his chase of Nezuko after she and Murichrio started dating and a year later he somehow to everyone’s shock got married to a girl from the south.
“Sorry we’re late everyone, Mitsuri broke a hole in the wall when she found out that the twins were born. You don’t want to know how difficult it is to calm her down and three kids (age 3 and 1).” Obania said as Mitsuri ran to hug Kanao. Soon after the defeat of Doma Obania confessed his feelings for Mitsuri which she gladly accepted. They married at 20,22. They then had a pair of twins at 22,24, and had another child last year. Mitsuri decided 3 was enough because she didn’t have to divert too much time off her hashira duties.
The next day Giyu came to Tanjiro, seeming unsettled. “Guyi what’s wrong?” Tanjiro asked, seeing the sadness in Giyu’s face. “Urokodaki has passed.” Giyu said as tanjiro ran in for a hug seeing that his friend was in pain.
“First my parents, then my older brother Sabito, then Rengoku, then the master, and now my sensei has died.” Giyu stated as he put flowers on Urokodaki’s grave. “Mr Urokodaki, without you me and Nezuko would have never been able to get to where we are now. Please rest easy knowing that your teachings have saved countless lives.” Tanjiro and Nezuko said as they paid their respects to their master.
Zenistu looked down upon himself. His grandfather committed suicide when Zenistu’s brother turned into a demon and died on the Mugan train. He vowed from that day on to not be afraid. He doesn’t need to sleep to activate his true strength.
Lady Tamayo was now the leader of the demon slayers and had a plan to kill Muzan. During the next eclipse the infinity castle will be exposed to the mortal realm and can be entered. On that day the plan is to destroy Muzan.
Meanwhile Murichrio stares at the clouds with Nezuko. “What was the name of that flower again?” Murichrio asked his wife while they sat at the butterfly mansion. “Pretty sure it’s wisteria, it’s what we use to keep captured demons for final selection.” Nezuko replied as she went in to snuggle with Murichrio. When Nezuko was 17 she went on a mission with Murichrio to hunt down a hawk demon. After the battle Murichrio and Nezuko got udon to eat. While eating Murichrio and Nezuko started discussing their shared interest in knitting. After that the two started dating and when Nezuko turned 20 she married the mist hashira. Although the couple tried, they couldn’t have children due to Nezuko’s infertility. Although she was upset when she learned this, Nezuko kept looking on the bright side of life and with the support of her husband Nezuko got even stronger.
Genya felt worthless compared to the others. Even though he finally mastered stone breathing to the skills of a hashira and unlocked his mark, Genya still felt like he didn’t do enough to prove his worth as a demon slayer. (Snap out of it sh*thead, the demon slayers need you and your strategy mind besides you're already the 2nd in command of the 1st company and you’ve mastered stone and wind breathing.) Genya thought as he started his training.
Senjueo knew that something big was going to happen with the eclipse approaching. He heard that they plan to fight Muzan. (Have we really found him?) Senjuro thought as he was called for an emergency hashira meeting.
A few weeks later Tamayo saw Muzan approach the master’s old home. “Tamayo, I never expected to see you working for the demon slayers.” Muzan said as he got close to Tamayo. “Tonight is the blood eclipse. The last blood eclipse was during your battle with the first breathers if I’m correct.” Tamayo said as she sent out the last crows. “You were a fool to expose yourself.” MUzan said while grabbing the corps leader. “NO. Everything is going to plan. As we speak the demon slayers have entered the infinity castle (YOUR TRUE BODY) and are working to destroy the last of the demons you have stored in there. Farewell you bastard.” Tamayo finished as she ignited the TNT around the mansion, killing her and poisoning the demon king.
As Tanjiro looked at the explosion in the distance he knew that this plan had to work.
(Muzan I swear to finally live up to me and Nezuko’s promise of killing you and wiping demons off this world. Tonight you will die.) Tanjiro thought as he and the other hashira, even Tengen and Gyomei unlock their marks as they all enter the
INFINITY CASTLE!
