Water keeps moving but sometimes they get left behind...
---------------------------------------------
After he gives the boy the instructions, he quickly went to his station post to rest,

Tomioka go to one of the food stalls to get a food..

Until he hear a rustle,

He turn and saw a black cat,

Huh, why is there a black cat here?

Before he could thought of anything, suddenly the cat is being held,

He looks up and saw a little girl...

Wait, she is more like a teenager,

"Neko-san, don't go anywhere again.." the young girl said as she slowly make her face close to the cat, "You promise me you won't bother someone..."

The cat just reply with their own word,

The young girl look at Tomioka, "Thank you for watching over Neko-san, he is a lazy cat but energetic when he wants to.."

"It's alright.."

Tomioka felt a little awkward, waiting for his ramen..

"Ne, Hashira-san..."

...

Did this girl–

"Ara Tomioka-san! There you are!"

Tomioka turn around and saw Shinobu,

Shinobu ask why he didn't invite her to eat with him...

Tomioka didn't reply but keep on focusing the spot that the girl stand..

Years later,

Tomioka walk around the Water Estate in the Demon Slayer Corps...

There's no work for him...

As he walk around, he saw someone standing outside his estate..

That's the girl...

What is she doing?

Before Tomioka could do anything, the girl turn to him...

There's the cat from before,

"Ah, Hashira-san is here!" The girl voice is to soft but Tomioka could hear it clearly,

Before Tomioka could do anything, the cat from the girl hands jump out from her grasps...

And run towards him

Before he could react, he suddenly fell down with the cat..

The cat purr on him,

"Aww~ Guess there is a creature who likes you instead of a humans Tomioka-san~"

Tomioka turn around and saw Shinobu,

"Kocho, I am not dislike by anyone.."

"Keep telling yourself that~"

Tomioka turn to look at the girl but she gone again...

After that, Shinobu left to work on her estate..

Tomioka get inside the Water Estate and put down the cat..

Before he could turn away, suddenly he stops by someone,

"What a pain..."

Tomioka almost surprised, the girl from before...

Where did she come from!?

The girl look at him and then look at the cat, "Sleepy Ash, you can stop now..."

"No.. Too bright..."

Did, did that cat just talk???

Before he could said or prepared anything, the girl walk pass him and held the cat,

She pat it and turn to Tomioka, "Do you mind, we're staying for a bit..."

Then Tomioka felt like everything is dark as the girl look at him, still patting the cat,

"And I have a proposal..."

The girl, introduce herself, Inkuro Afuru, the traveler of different world. And her executioner, Sleepy Ash, the Servamp...

They offer Tomioka to join them..

Tomioka declined..

Sleepy Ash look at him and then back at Afuru, waiting for her to do something until Afuru get up,

"C'mon Ash, let's go.."

Tomioka still sitting and waiting the guests to leave until Afuru said something,

"After Tanjiro and his friends recovery, they will have a mission with the Flame Hashira, Rengoku Kyoujurou,"

She turn to Tomioka, "A bit of reminder, there will be two demons on their mission, one is from the lower moon while the other is the upper moon..."

Tomioka eyes widen and quickly turn to Afuru but she is gone...

How..

At night, Tomioka is ready to sleep until he saw something around the hall of his estate..

He came a little closer and suddenly froze...

There is a silhouette but the size, the clothes, everything that has on the silhouette...

Why..

"Sa.. Sabito..?"

Tomioka slowly steps back and the silhouette keeps walking forward...

No.. no.. No! No no no no no no no no no no no no no no no no No NO NO NO NO NO NO NO NO NO NO NO NO NO–

Then he pass out...

Tomioka slowly woke up,

It, it's a dream– "No,"

Then he quickly sat up and saw Afuru..

Afuru look at him with her stone expression,

She summoned something out from her hand and tap it,

"You have encountered the crack.. It should not be in here so why.." As Afuru thought on the case, she gives a glance at Tomioka, "Are you alright? What did you witness–"
"I saw Sabito..."

Silence...

Afuru sigh,

"You are lucky the crack isn't big, or else it will show you the full of this 'Sabito'..."

Tomioka quietly grip his blanket...

Why...

Why is this happening?!

Is his sin not enough to give?!

Does he deserves more punishment to the point he meet his dead best friend?!

First his parents where he never met, second his sister and now his best friend..

So, why!?–

"Daijoubu.."

Tomioka slowly look up and saw Afuru held his face,

Tears..

He is crying,

"You really are a water Hashira... Ugh.. this is awkward," Afuru turn away, "You're an adult and yet here I am wiping your tears... Stops crying, crybaby.."

"Giyuu! Stop it! Your not a crybaby right?!" Sabito...

Afuru held his face with both her hands, "As the water flows, the river follow it. No matter what, the water will continue on moving... But when they have a travelling buddy, sometimes, those buddy... Will fall under the deep sea.."

The tears won't stop, Afuru let go of his face,

"Greetings, my name is Inkuro Afuru, the Inane. You, Tomioka Giyuu, the Water Hashira, the Aqua.. You have been chosen as the Spiritual of my team, consider your world is.. full of spirits... You will be guarding the Life of Realm, and help us recover those who have been gone by the cracks on their world... So, dear Aqua, would you mind joining us?"

Tomioka look at Afuru and hold her hand..

He accepted.
