"Y/N, don't you want to put a band-aid in that?" Tanjiro comments, looking at the cut in my cheek.

'Jeez, why is everyone so worried about such a superficial cut?'

"It's fine. By the way, doesn't your nose hurt? I'm still drenched with alcohol and all, if the smell is too strong for you I can get away." I say worriedly, letting go of his hand.

"NO!- I mean- no, there's no need to! I- I'm used to way stronger smells so- well- what I'm trying to say is-"

Watching him fumble with his words is more fun than I thought, and I wasn’t even trying to tease him this time, which make it even more amusing.

But I should probably stop him before he passes out.

"Here, I'm not letting go, okay?" I smile at him, holding his hand again.

"I'm also not letting go of your hand! Ever again!"

"…? Yeah."

☆

Y/N didn't notice the more profound meaning in his words at all.

The rest of the way back to the butterfly mansion was silent.

Well, most of it was because when as they got closer a weird sound appeared.

"…is that…is someone screaming?"

Y/N asks in a concerned way, Tanjiro tightens his grip on her hand, the girl got extremely surprised when she looked at his face and saw that he had this 'I'm doomed' expression.

"ᴛᴀɴJIROOOO!"

Tanjiro was welcomed with a kick in the face by Zenitsu.

"HOW DARE YOU GO OUT ALONE WITH Y/N! AND YOU ARE EVEN HOLDING HANDS WITH HER!"

"Zen?"

"Ah, yes?" He turns back to her, completely changing personality.

"Here. It's a rock." She says, putting a rock in his hand.

"I don't understand why are you giving me a rock, but thank-WHAT HAPPENED TO YOUR FACE?" He screeches, putting his hands in her cheeks and checking each side of her face.

"WHO DID THIS? WHO HURT YOUR ANGELIC FACE?"

Yeah, she kinda expected this reaction of him.

"Y/N is hurt?!"

"She is?!"

"Where is she?!"

Naho, Kiyo and Sumi suddenly appeared while crying.

"I'm not-"

"Y/N, is everything okay?" Shinobu also appears with her usual fake gentle expression, as she took a closer look at Y/N's face, her smile started to twitch.

"My my, would you mind enlightening me about who did such an act?" She asks with an ominous aura.

"What are you gonna do with them if I tell you?"

She just smiled at her. Menacingly.

"Y/N got hurt?! Is she going to die?!" Kanao suddenly pops up from behind Shinobu, looking like she was about to cry.

"Of course she's not going to- WHAT HAPPENED TO YOUR FACE?"

Now Aoi is also there.

And that's how the butterfly mansion was thrown into chaos all because of a scratch in the cheek.

♡

Phew, they finally left me alone.

I know that they are still getting over me almost dying in the train mission thing, but there's no need to be so dramatic over such a small cut.

Now…it's time to read it.

The records about the seraphic breathing.

I don't why am I so nervous about it….

I took a deep breath, carefully opening the old book and starting to read it's contents.

________ 

If you are reading this, then you are probably a Seraphic Breathing user.

Mirieth put a spell in this book, so it will look like gibberish for other people, don't worry.

This used to be my diary. I'm writing this after I finished it because I thought it would be of help to you, someone who was blessed with the same powers as me.

DAY 1, YEAR ???

I finally learned how to use a breathing! A god called Mirieth said that it was a power supposed to be created in the future by someone called Yoriichi or something, a power from the future? How intriguing!

DAY 2, YEAR ???

Mirieth said that she loves me! I also love her a lot, but I was too shy to say it aloud to her.

DAY 3, YEAR ???

My nose keeps bleeding from time to time, I hope it's nothing serious.

DAY 4, YEAR ???

Mirieth said that she is the god of future, and that she saw mine, and I am supposed to die tomorrow, how creepy! She said she would avoid my death, so I guess I will be okay?

DAY 5, YEAR ???

I'm alive. My nosebleeds got worse though, hope it's not related.

DAY 30, YEAR ???

I was supposed to die today too, but my destiny was changed again.

DAY 52, YEAR ???

My body feels heavy and tired, I hate this.

DAY 64, YEAR ???

She taught me how to use that breathing, but what am I supposed to fight anyway?

DAY 81, YEAR ???

Demons. Everywhere. I hate them.

DAY 191, YEAR ???

My body can't hold on anymore.

DAY 234, YEAR ???

I couldn't save anyone today. I'm so sorry.

DAY 318, YEAR ???

I'm so useless.

DAY 421, YEAR ???

DAY 2346, YEAR ???

I think this is my end. I am supposed to die tomorrow, and there's nothing that Mirieth can do about it, so this is for real.

She told to me what she saw in the future, she said that someone just like me will need my help.

So I will document what I know, I hope it helps you, mysterious person.

Seraphic Breathing.

A breathing who can only be used by a person who has these two conditions :

One: having a body unable to use the normal breathing techniques.

Two: be loved by a god.

Because of the second condition, me and you who are reading are probably the only ones who could use such a technique, after all, gods rarely get in contact with humans.

Gods don't understand human emotions, but when they love, they love hard and are unable to let go.

They will never let you die as long as they are capable of avoiding it.

So, having their favor is both a blessing and a curse.

About the seraphic breathing, it has an effect similar to the demon's slayers mark.

Strength in trade of your life.

I'm sorry, but the seraphic breathing use your life span in trade of making your body compatible with it, so, just like me, you will probably die beyond what a god can repair.

You are probably already aware of the fact that demons killed by the forms will be able do go to heaven, me and you are going to be punished for forcibly opening the gates.

Punished by death.

The more you use the breathing, the sooner you will die, be aware of the signals.

Bleeding. Tiredness. The feeling that everything is going end. The feeling that the world is made of suffering

.But I believe with all my heart that there is way to recover it, so, mysterious future person, I will be cheering for you to find a way to live, Mirieth also said that she will help when the time comes, whatever she means with that. 

She promised she would help, and a god always keep their promises. Remember that.

I don't know who you are, but assuming that we are equals, all I want to say to you is :

Live. Keep living. Even when everything seems dark, even if you don't have any hope for tomorrow, keep pushing. You can't save everyone, but your life is as precious as other lives are. You can't save others if you don't save yourself first, so, live.

If I myself had realized this sooner, then maybe things would have been different.
