Btw if any of you got ideas for Tensura skills that would be great for a Demon Slayer aside from the ones I already listed that would be great and don't make it too op, please








Days passed Nezuko and Rimuro were in a cave waiting on Tanjiro

Rimuro: So how well can you control your size

Nezuko: I have been practicing largest I can get is the size of an older woman the smallest I can get is small enough to fit in a pocket

Rimuro: That may come in handy if we need to carry you around during the day

Nezuko: . . . Rimuro I'm honestly worried

Rimuro: Tanjiro and I will turn you back into a human we promise we'll become stronger so don't worry

Nezuko: But Rimuro I've been feeling an immense hunger ever since I've become a demon what if I-

Rimuro: YOU WON'T

Nezuko: Rimuro I'm sorry to ask this of you but I'm only asking this because I know Tanjiro is too gentle to-

Rimuro: Nezuko please don't say what I think you're gonna say

Nezuko: If I ever so signs of eating anyone please promise me that you'll end my life on the spot

Rimuro: . . . Nezuko you know I can't promise that

Nezuko: There's no one else I'd ask Tanjiro is far gentler he'd blame himself too much I don't want either of you blaming yourselves it's not your fault

Nezuko: Rimuro, please

Rimuro: If it comes to that all I can promise is that I'll stop you and I don't care what the world will think of me or do to me I won't let either you or Tanjiro die

Nezuko: . . . Fine I'm sure you know best

Unknown to the 2 Tanjiro heard the whole thing

Tanjiro: (She doesn't trust me to do it well I understand Rimuro has always been better than me he doesn't deserve to have the guilt of doing this don't worry big brother I'll do it for you you're the last person who deserves the guilt of doing such a thing) Hey I'm back

Rimuro: Oh hey Tanjiro

Nezuko: Do you have any food

Tanjiro: I was able to get a basket and some lunch for all of us

Rimuro: And by get you mean force someone to take your money for an old basket then you got us some lunch

Tanjiro had a look of slight surprise and embarrassment on his face

Tanjiro: You know me so well brother

Rimuro: You didn't have to do that you know sure we have lots of money left but still we should use it sparingly

Nezuko chuckled

Nezuko: That's Tanjiro for you can't help but feel he has to compensate everyone for doing anything for him

Tanjiro: Right I'm sorry

Rimuro: (Maybe I should go into town next time)

Tanjiro: Let's eat before we continue we don't know when we'll have the time to rest again

Rimuro: Good idea so what did you get us

Tanjiro: I bought 3 boxed lunches

Nezuko's mouth was visibly drooling

Rimuro: Let's eat

As the three ate their respective meals they were quite shocked to see how Nezuko was scarfing hers down

Rimuro: You really were hungry huh Nezuko

Nezuko suddenly realized what she was doing and was slightly embarrassed

Tanjiro: Here you can have some of mine

Nezuko: Oh no it's fine you don't have to

Nezuko's stomach growled loudly

Nezuko: . . .

Tanjiro: . . .

Rimuro: . . . Maybe you should have some of mine too

Nezuko: Thank you

After Nezuko easily fit in the basket they left for the mountain

Rimuro: We've made good time the sun just came down and we're already a good distance up

Nezuko: It was nice of that mother to tell you both the way

Tanjiro: Look, a temple

Rimuro: Let's keep moving the sun has barely come down

Nezuko: Good idea best not to trouble them

The trio continued the path until suddenly a dark figure tried to sneak attack them

Temple Demon: (3 kids out alone at night easy pickings young flesh will make for a good meal)

They all dodged him and jumped away from him

Temple Demon: (What how are they so quick)

Rimuro: We all knew you were there which is why we didn't stop

Tanjiro: We needed to make sure those innocent people were safe

Nezuko: Now we don't have to worry

Temple Demon: Hold on your a demon aren't you what are you doing teaming up with humans

Nezuko: What you'd expect me to team up with strangers who would turn on each other instead of my own brothers

Tanjiro: The time for talking is over

Tanjiro took a deep breath

Tanjiro: Sun Breathing First form: Dance

Tanjiro slashed the demon in half with relative ease

Temple Demon: (What was that he was so fast I couldn't see him wait I should be able to move my body but why can't I stop shaking)

Rimuro: I figured this wouldn't be enough to kill you

Rimuro sliced the demon into multiple parts it was too in pain to move

Temple Demon: AAAAGH YOU BRATS I'LL KILL YOU ALL FOR THIS AND THOSE PEOPLE YOU WERE TRYING TO PROTECT

Tanjiro: Such disregard for human life

Nezuko: What's so amusing about this

Rimuro: Answer what is the weight of a human life to you

Temple Demon: (These words why do they sound so familiar they terrify me why)

Rimuro: (It's a good thing that Yoriichi left that book of details on sun breathing and it's been intact for generations must've wanted his bloodline to be able to protect themselves with it Tanjiro knows all the forms already the rest should be easy)

Tanjiro: He's still alive

Rimuro: If we don't finish him he'll hurt more people I'll try dicing him up till there's little left look away

Tanjiro: That sound's pretty cruel it's a shame there isn't a way to do it more quickly

Nezuko: Hold on let me try something

Nezuko walked up to the remains of the demon and put her hands on them suddenly pink flames engulfed the demon he was incinerated in seconds

Tanjiro: Where did that come from

Nezuko: I discovered that I could make these when we were traveling I noticed they couldn't burn anything so I figured they must have a specific target and I was right

Rimuro: Clever Nezuko

Nezuko: I didn't think he'd burn up so much though

Tanjiro: Well at least it's over

Rimuro: So tell me how was that

Sakonji: So you noticed me impressive

Tanjiro and Nezuko were both shocked as they didn't notice him

Tanjiro: Are you Sakonji Urokodaki

Sakonji: Yes I assume that is the sister you spoke of

Rimuro: correct

Sakonji: What will you both do if your sister ever eats a human

Rimuro and Tanjiro: That won't happen

Nezuko: But if it does I'll walk to the sunlight myself

Sakonji: (What I can take from these 3 the blue-haired boy brings off an air of guilt and extreme restraint he seems as if he's hiding something along with his true power the other boy with red hair while also holding back has a certain compassion even for his enemies still they have potential and as for her she smells like no other demon I've ever seen as if someone altered her to be different than any other demon these 3 are special I fear what I have to teach may not be enough for them) Very well I will test whether or not you're fit to become a member of the Demon Slayer Corps follow me

The 3 ran with Urokodaki to the destination he was going they easily kept pace with him they were at his speed

Sakonji: (Impressive they're all able to keep pace with me and I can't hear their footsteps these 3 have some talent and they can, possibly, only be holding back out of ignorance to where we're going)

They made it to his abode easily the sun was still down when they did

Tanjiro: Is there anything else

Sakonji: We'll be climbing a mountain

Rimuro: Nezuko you stay here this training is for Demon Slayers

Nezuko: I'll be waiting for your return

The duo of brothers followed Urokodaki up the mountain until Sakonji stopped where he was

Sakonji: Now find you're way to my house at the foot of the mountain you have until daybreak

Sakonji disappeared from their sight

Rimuro: I seriously have to figure out how they do that alright ready Tanjiro

Tanjiro: Yes

Rimuro and Tanjiro both closed their eyes and used their other senses with them Tanjiro was able to smell where to go and Rimuro could concentrate his Magic Sense to know where to go

Rimuro: Seems like there are some traps on the way

Tanjiro: It seems so

Rimuro: Well only one thing to do then

The brothers nodded at each other they then got into sprinting positions and took off whenever they sprung the traps they were too fast to get caught by them or they simply dodged the attacks they made it back in less than 10 minutes Sakonji was quite surprised to see them back so quickly and without so much of a scratch to show for it

Sakonji: You 2 are already back and in such a short time (It seems Tomioka was right I can understand how they defeated him) you're both now my new students

The brothers trained together under Sakonji and did everything he asked with flying colors they surpassed his expectations in only 2 months they fully mastered Water Breathing until their final trial they were brought to a location with 6 stones organized by 3 of each were being placed in line

Sakonji: if you both can cut these boulders in 2 I'll allow you both to enter the final selection

As soon as he turned around to leave he heard several slashing sounds and looked to see that not only have the brothers cut the boulders in 2 they diced them into pebbles

Rimuro: It's a shame we couldn't meet you 2 but know that we will allow your souls to rest in peace when we defeat THAT Demon

Tanjiro: Did you say something Rimuro

Rimuro: I'm just muttering to myself is all

Sakonji: It seems you 2 are ready

Rimuro: If it's all the same to you Sensei we'd like to train more before we go

Tanjiro: We've both discussed it and we think it would be beneficial

Sakonji: Understood

The 2 trained an extra 2 years mostly only because Rimuro insisted on it not wanting to stray from the original starting point

Rimuru is still taller and older than Tanjiro but here's a reference as to what he looks like after the 2 years

Tanjiro's hair grew out he kept it in a ponytail

In that time the 2 mastered the Total Concentration Constant and not only did Tanjiro master Water Breathing he also learned the 13th form of Sun Breathing when 2 years passed they finally felt themselves ready for Final Selection they received the Masks from Sakonji

Nezuko: Now be safe you

Rimuro: You know this'll be easy stuff for us Nezuko

Nezuko: Never the less I don't want you 2 getting cocky

Tanjiro: We'll be careful

The 2 left for Final Selection they were some of the first to arrive as they waited Rimuro scouted over the others

Rimuro: (There's Kanao, Zenitsu, and Genya, Inosuke must've rushed ahead or something)

They listened to the briefing and the rules of Final Selection then they began

Rimuro: Let's split up and meet at the safe point on the other side of the Wisteria

Tanjiro: Ok

While they were splitting up Rimuro secretly followed Tanjiro and was proud to see his accomplishments he vanquished every demon that came near him till he reached the Hand Demon

Hand Demon: Well look at that it's another one of those sweet little foxes

Tanjiro: What are you talking about

He then explained the purpose of the masks and how he's killed multiple of Sakonji's students and laughed upon hearing this Tanjiro became furious

Tanjiro: What do you find so entertaining what's so amusing about this

With these words, the Hand Demon shuddered and saw flashes of images he couldn't understand, and before he could answer

Tanjiro: Sun Breathing Fifth Form: Setting Sun Transformation

Before he knew it the Hand Demons' head was cut off he was finished Tanjiro gave the demon his sympathy and left he then made his way to the safe point to see Rimuro was already there together they passed Final Selection and saw only 3 other people Rimuro recognized all of them

Tanjiro: Only 5 of us we started with only 20 shouldn't we have saved them

Rimuro: . . . Maybe but would they have been able to survive as Demon Slayers if we had

Tanjiro: Still. . .

Rimuro: I understand but don't blame yourself

Zenitsu: I'm gonna die I'm done for I've survived for now but soon enough dead

Rimuro: Don't say that

Zenitsu looked at the voice of the one who said that

Rimuro: You've made it this far I'm sure you can continue to believe in yourself I'm sure you have a great talent if you've survived this long just be confident

Zenitsu was put off guard by the kind words hurled at him

Kiriya and Kanata gave introductions on the basics of being a Demon Slayer until they were interrupted by Genya as he grabbed Kanata's hair

Genya: I want my sword right now give it to me before I get angry the color-changing katana I WANT IT NOW DO YOU HEAR ME

Tanjiro grabbed Genya's arm

Tanjiro: Take your hand off her or I'll break your arm, NOW

Rimuro: Tanjiro's right that's no way to treat our hosts

Genya: Huh who the hell are you 2

Zenitsu was slightly panicking at the situation

Genya: Give it your best shot

True to his word Tanjiro slightly tightened his grip a cracking sound could be heard

Genya: AGH

Kiriya: Are you finished chatting with each other

Rimuro: I can't tell if he's teasing us or not

The group were revealed the ore to use Tanjiro and Rimuro picked based on their senses they headed back to Sakonji's home it was afternoon by the time they made it back

Tanjiro: I'm such a fool I forgot to ask any demons about how to turn back into a human

Rimuro: Our journey of fighting demons has only just begun there will be other opportunities and more practical ones as well I'm sure of it

Tanjiro: Yeah you're right

They neared back to the house but suddenly the door was opened to reveal Nezuko to the brothers' shock

Tanjiro: Nezuko

Rimuro: You're in the sunlight

She said no words as she rushed to hug her brothers

Nezuko: I'm glad you guys are safe

They both hugged their sister and cried tears of joy happy to see her in the sun

Urokodaki joined them just as happy to see Nezuko alive in the sun and to see Tanjiro and Rimuro both come back alive

Sakonji: You're both here you both came back alive

Rimuro: (I don't care if doing this for her was cheating I'm gonna make sure this is a journey the 3 of us will continue to share together)
