Again, sorry about the prank 💀

It has been 3 months since Tanjiro and his squad started training using Saitama's Training Method.

Naho, Sumi and Kiyo are the alarm clocks for the squad (Saitama requested this since there are no roosters or real alarm clocks), if the time is set on time, the little girls will use wooden spoon to wake them up.

Their physical growth gradually increasing as they became stronger than their previous selves. Their physical attributes and mental awareness also improves.

They also exercise everyday and their bodies are changing and becoming tougher. Their breathing concentration also becoming much better.

Tanjiro, Inosuke and Zenitsu improved a lot and become more better as they train without being lazy.

Tanjiro beats Kanao in a friendly game like cup games and friendly duel, he is being gentle than Inosuke mercilessly wrestling Aoi. While Zenitsu in a different scenario gets beaten if he acts stupid.

Meanwhile Saitama was just lazing around at the butterfly mansion, waiting to be called in a demon slaying request.

But..

The squad received an order from the corps....

A Kasugai Crow delivering a message.

[Flapping Wings of the Crow]

The crow flew at the window and grabs the attention of the squad who was cleaning at the foor.

The crow then shouts "KAW!! Orders from the demon slayer corps! Assist the flame pillar Kyojuro Rengoku during the investigation in the Mugen Station, that's all! KAW!!"

Saitama recognized the crow who was being pesky of him since the day they met, the hero makes a funny look and says "hey! you are the annoying bird who peck me over and over again....??? How dare you, how dare you mock me!? I'm now a pillar, so if you dare mock me--"

The hero suddenly realized that the crow wasn't listening to him, he felt a weirdo talking to the air.

The crow wasn't listening as it flies away very fast outside "the 3 of you except mister saitama must go now and assist the flame pillar immediately!! KAW!!"

"Oi!!! Listen to me you pesky annoying irritating bird!!" Yells the annoyed Saitama, the hero crosses his arms and mutters by himself.

The hero walks outside while trying to think what he should do next. The hero doesn't accept leaving Tanjiro and his squad alone since he promised to Sakonji to accompany Tanjiro everytime they go on a dangerous mission, so the hero plans to join with them.

Tanjiro felt awkward while Inosuke was amused of the hero's behavior.

"Hey Kamaboko, why is the old man hates that talking bird? Does he have an issue with that bird?" Asked Inosuke while being curious

"Um....you don't need to know...it's a long story.." Tanjiro smiles and laughs awkwardly.

[Grunting noises]

Zenitsu grabs their shirt and drags them outside while saying "are you two deaf!? We need to prepare for our journey right now so let's plan it outside with mister Saitama!!"

Tanjiro was startled and says "Calm down Zenitsu, are you excited to go now? Isn't that crow told us that only the 3 of us must go except mister Saitama???"

"I refuse!!! Mister Saitama must accompany us!!! You know that he won't accept leaving us alone right!?" Yells Zenitsu as he keeps dragging them outside.

"Oi yellow head! Don't drag me like an animal!" Yells the mad Inosuke.

Meanwhile at the outside with Saitama.

Zenitsu and Inosuke has a heated argument.

"You're not the boss here!!! It's Kamaboko or the old man Sadtaman!! Don't order me around like you are the leader!!" Shouts the pissed off Inosuke to the mad looking Zenitsu.

"You are the most stubborn here!! You must listen to your superiors and obey them!!" Disciplines the mad looking Zenitsu to Inosuke.

"HUH!? Says by the crybaby who is scared of the demons, pathetic!!" Inosuke talks back while fuming with steam. He is prideful and short tempered in arguments, but it's a miracle he is not punching Zenitsu.

Tanjiro being the mediator goes at their center to break the argument and tries to calm them down "chill guys! Let's make mister Saitama decide what is the best..."

Saitama is annoyed of them, but his face looks poker. The hero unknowingly released a scary aura that makes Zenitsu and Inosuke behave obediently like a scared puppy.

The hero then warns them "the two of you are so noisy, should I put you both in my lap and smack your asses right now??"

Zentisu and Inosuke smiles nervously while looking away, then they shake their head to refuse getting scolded.

Tanjiro let out sigh of relief as the commotion tune down. He then ask the hero "mister Saitama, the corps asked us to go there to support mister Rengoku, so we will gonna be parting--"

"No...I'll be accompanying you all during your mission" Saitama smiles while his hands at his waist.

"Ahhhhh!! Mister Saitama is accompanying us!!!" Zenitsu smiling widely with his eyes all teary

"Old man is worried of us, right??" Asked Inosuke while feeling relieved.

"Sighed..." The hero facepalming himself, but later he smiles at them.

The hero chuckles and says...

"Come on, the three of you must prepare now..." Saitama being a guardian to the squad.

1 hour later before the departure...

Tanjiro meets with Aoi, Naho, Sumi and Kiyo to tell them about their mission.

"Is that so....well...all of us will gonna miss you and your squad, I hope all of you will be back sooner..." Says the worried Aoi.

Naho, Kiyo and Sumi was kind of sad as they grabbed Tanjiro's hand and says "big bro Tanjiro, are you all going to an important mission??"

Tanjiro chuckles, giving them each some headpats while answering "yep, we promise to be back here in perfect shape, we have mister Saitama, so the mission is guaranteed a win" he grins.

The girls seem happy of Tanjiro's response, they have faith from the squad especially Saitama being with them.

After the friendly chatter, Tanjiro went back to his room to prepare.

And then, the time has come when they wave their farewell and goes on a temporary mission with the flame pillar. Since the power pillar joined with Tanjiro, it is still unknown what enemies are bidding in the shadows.

After Saitama and his squad went to the train station, they take train tickets and head inside the train where the flame pillar was taking a ride.

[Inside the Mugen Train]

"Wow this bug is super big!! So many people getting eaten here...." Inosuke snorts while looking around at the passengers

"It's not a bug you dumb boar! It's a train, a vehicle!!" Zenitsu being annoyed of the clueless Inosuke.

Inosuke wasn't listening as his curiosity pique in interest.

Inosuke slams his palm at the window as he watches the train moves.

He yells like "so fast!!! The bug is now moving!!"

Zentisu yells "stop slamming your hands at the window! Or else it will break!"

Saitama sighed at their noisy behavior and told them "let's go kids, let's find the flame pillar guy boarding here..."

"DELICIOUS!!!" Shouts of the flame pillar at the other area.

The squad exclaimed at the sudden shout.

All of them were startled.

[Crowd noises getting startled]

The squad opened the door and the loud noise continues "DELICIOUS!! DELICIOUS! DELICIOUSSSS!!!"

The flame pillar's shout startled all passengers inside the train.

The curious Saitama was kind of surprised of how the flame pillar over praised the food like his life depends on it "what a weird dude.."

It's because the flame pillar is eating 20+ bentos non-stop, he is a glutton.

"Mm~ Delicious!!" Shouts Rengoku as the bentos are flying up each time he compliments the food.

"Kyah? That's the flame pillar!?" Asked the scared Zenitsu who is creeped out of Rengoku's behavior.

The squad approached the busy flame pillar and decided to intervene.

The awkward Tanjiro while smiling nervously asked like "um....mister Rengoku....can we...um..."

"State it fast Tanjiro! I am creeped out here!!" Says the nervous Zentisu who is hiding behind Tanjiro.

Rengoku continue to eat but he responded "oh the 3 of you are sent here to assist, correct??"

Tanjiro and Zenitsu nodded while sweating a lot.

"Oi, what do you mean 3?? Am I forgotten here?? Is my existence not important here in the mission??" Saitama in annoyed look

Rengoku laughs in lively tone as he responded "that's a different case mister pillar! I know you are here for another business, no?"

"Nope, I am accompanying Tanjiro here because I wanted to..." Says the poker faced Saitama.

Rengoku nodded while smiling brightly and gestures them to sit down with him "okay! So first have a seat with me and let's talk!"

Tanjiro sits beside Rengoku while Saitama sits at the other chair facing infront of them

While Inosuke is being busy slamming his palm in the window because he wants to race with train "let's see who's faster between me and this giant bug..."

Zenitsu holds him off while disciplining him "stop slamming your palm there damnit! The glass will break!! And don't just go out there like you are faster than the train!!"

Meanwhile....

The flame pillar Rengoku asked..

"Mister Saitama and Tanjiro, I am grateful of your help, but I must say I will be solving the case by myself, because you know this is dangerous and I don't want anyone to get involved" Says the smiling Rengoku while crossing his arms. Rengoku has a friendly charisma, the atmosphere seems bright and lively.

"Relax man, I heard that Tanjiro wants something from you..." Saitama looking at Tanjiro

"Eh?" Tanjiro feeling embarrassed and hesitated to ask.

"Oh I see...tell me!" Says the lively Rengoku as he looks at the embarrassed Tanjiro.

Tanjiro was embarrassed as he tremble and looks at Saitama "w-what do you mean by that mister saitama??"

"I heard you the other night you wanted to ask the flame pillar about the Kagura thing right??" Says the nonchalant Saitama

"A-ahh that!!" Tanjiro's eyes lit up, he then looks back at Rengoku and says "if you don't mind, can I ask about
