Once, a long time ago, there was a young child.
A few years ago, a child arrived holding the Master's hand. Despite being only 11 years old at the time, the child possessed such outstanding skills that they grew up receiving everyone's respect and love.
Because the child had such a strong image, we didn't hesitate to send them on difficult missions when high-level tasks were assigned. The child always returned with a bright smile after completing a mission—except for that one time.
Days passed after the child was sent on the mission, but no news arrived.
Then, after several weeks, you returned.
Actually, it wasn't you, but a child who was meant to replace you.
When that child first arrived, everyone was just full of questions about you. Why didn't you return? Did you quit the Demon Slayer Corps? Those thoughts filled our minds. Yet, gradually, we became accustomed to Rin, the child who replaced you.
You were slowly forgotten.
A few years later, on the day marking exactly one year since you failed to return, the thoughts and curiosity about you that had been forgotten for a year suddenly came rushing back. So, that day, we went to the place where you were last assigned.
All that remained there was a broken lily-of-the-valley hair ornament. Since you wore it every single day, we realized then that you were dead.
...
However, not long after they visited the place where you died, you were reincarnated.
In the exact same form as when you died.
But when you returned to the Demon Slayer Corps, the Hashira had already forgotten you and become accustomed to Rin.
Since they already had a lovely child, they were indifferent and cold to you—the newcomer to them, but the original owner to yourself.
Even so, subconsciously, they kept trying to look after you whenever Rin wasn't watching.
Because they loved you, they couldn't let go.
Drive Rin out and find happiness with them once again.
I can't remember right now. Who was it... one of the children from the Butterfly Mansion? Asking me not to forget you... It feels like I've already forgotten.
It was a child whose identity I couldn't recall, yet who felt strangely familiar. ..
It feels like my mind is submerged in mist. It's been years of not being able to remember things like this. It seems I've completely forgotten my memories of you. No, did we even meet in the first place?
Even though he is scowling, the way he keeps glancing at you makes it look as if he's worried about your well-being.
