Izumi

“Tsukuyomi.”

Izumi froze in place.
Itachi focused his thoughts on his own genjutsu. Tsukuyomi allowed him
to completely control time, space, and matter. It was a power he had gained
when he activated the Mangekyo sharingan. The time that passed within this
genjutsu was one one-hundredth of one one-thousandth of one one-millionth
of that of the real world.

Itachi drew out a clear image. Peace in the village of Konoha, the clan
tranquil. His own form, freed from all trouble.
And Izumi beside him, smiling.

Izumi becomes a chunin, as if chasing after him. At that time, Itachi is
already a jonin.
He hands a pouting Izumi an engagement ring.
Izumi retiring as a ninja.
Marriage.
Childbirth.
Child-rearing.
The children setting out.
Izumi growing old together with Itachi.
Seventy years since they met.
The hair on both of their heads is white.
Izumi’s illness.
He takes care of her.
Her last years ...
The Mangekyo sharingan consumed an enormous amount of chakra, and
so placed an equivalent burden on the user. Shoulders rising, Itachi took a
deep breath, as if crawling up from the depths of the ocean. Before him, Izumi’s knees gave out under her, and she collapsed, smiling.

Sliding over, Itachi held her up, tightly gripping her slender shoulders.
“Thank you.” Izumi’s voice sounded like that of an old woman past eighty
years of age.
“Me, too. Thank you.” He squeezed her shoulders more tightly, and could
say nothing more.
With a broad smile on her face, Izumi took her last peaceful breath.

The mind and the body were indivisible. If the mind decays, the body also
falls apart.
Izumi died, joyful.
After gently laying the now motionless Izumi down on the floor, Itachi
staggered to his feet. The intense expenditure of chakra made his body shake.
I decided that Izumi would be first ...

By killing her himself, he wiped away the last of his hesitation—the
hesitation borne of unfinished business with the clan, of bonds of emotion.
“Thank you, Izumi.” Itachi slowly turned around. There lay her mother,
knocked unconscious by the sharingan.
