Due to a one-shot bullseye, Uchiha Eto very soon discovered that she was already pregnant.
However, she didn't tell Uchiha Byakuya right away.
"Did something good happen? You seem pretty happy."
Byakuya naturally noticed that Eto was in high spirits and felt curious about what had happened.
"Do you want to take a guess?"
Eto instantly teased him.
"How would I guess that? At least give me a hint."
Byakuya replied with a slightly awkward tone.
"Then I'll give you a hint, put simply, it's something good and also, it's completely your fault!"
Eto said in a playful tone.
"Something good... and it's my fault?"
Byakuya immediately fell into thought.
He still couldn't figure out what good thing he might have done.
Seeing that Byakuya was still deep in thought after a long while, Eto Yoshimura decided not to mess with him any further.
"You Idiot... fine, I'll give you a more specific hint."
As she spoke, Eto placed her hand gently on her lower abdomen.
Upon seeing this, Byakuya finally had a sudden moment of realization.
His eyes widened slightly, clearly showing his disbelief.
"That fast?"
Byakuya exclaimed in surprise.
It had only been about ten days, right?
So that means... he really did get it in one shot?
After all, he hadn't done it either before or after that time.
"To be honest, I was surprised too. And happy. But I'm also kind of at a loss... I'm suddenly going to be a mom."
Eto lowered her head slightly, as if trying to sense the little life within her.
Byakuya also felt a complicated, indescribable emotion rise up within, but without question, "happiness" made up most of it.
Several months passed since then, nearly a year had gone by.
Byakuya had been taking care of Eto for almost every single day, especially during the later stages.
He also, of course, tried his best to prepare all kinds of nutritious dishes and soups to supplement her diet.
Now, inside the café, Anteiku in the 20th Ward, Eto was already sporting a pronounced baby bump.
"Our daughter, have you thought of a name for her yet?"
Eto asked Byakuya.
They had already gone to the hospital for a check-up and confirmed that the baby was indeed a girl.
Nowadays, with the growing momentum of peaceful coexistence between humans and ghouls, a lot of major hospitals in the Tokyo region were also open to receiving ghouls.
Not to mention special individuals such as Byakuya and Eto.
"Ahaha..."
Byakuya gave an awkward laugh.
Because he was the classic type of guy who was bad at naming things, he had spent several days thinking before finally coming up with a name he thought was decent.
He just didn't know whether Eto would actually like it.
"The name I came up with is 'Uchiha Aiko'. What do you think?"
Byakuya asked.
"Not bad, it actually sounds pretty nice."
Eto nodded slightly.
Although Kirishima-neesan and Irimi-neesan had also given them a few suggestions before, in the end, the name they themselves came up with still felt the best.
"Aiko-chan, did you hear that? This name was picked by your daddy."
At that moment, Eto gently stroked the child inside her belly, speaking in a soft and gentle tone.
Thanks to her special body as a half-ghoul, Aiko-chan wouldn't be as prone to ending up a miscarriage as other hybrid babies.
At the hospital, the natural delivery went very smoothly.
Little Aiko came into the world.
Eto's body was almost completely fine as well. After all, she had an extremely exaggerated regenerative ability, her body recovered immediately, showing no signs of just having given birth.
At that moment, Byakuya was sitting at the bedside, holding the newborn Aiko in his arms, while Eto sat closely beside him, watching the newly born baby.
"What a cute little one. And she really does look a lot like us."
Eto had a look of doting affection on her face.
Now she could more deeply understand the feeling her own mother must have had when giving birth to her.
That kind of feeling, only when you experience it yourself can you truly comprehend it's nature.
"Yeah, even her hair color is perfectly inherited."
Byakuya sighed with emotion.
Influenced by the parents' traits, Aiko Uchiha's hair was a mix of white and green, but it didn't look weird at all. Instead, the combination of both white and green was quite harmonious, so it looked rather beautiful.
And although her facial features weren't yet fully developed since she had just been born, the resemblance was already visible.
Byakuya and Eto were both very attractive, so with features inherited from the both of them, Aiko was guaranteed not to be anything less than beautiful.
Aiko barely cried at all. She was quietly watching her parents while sucking on her little thumb while wearing a cute smile on her face.
"By the way, is Aiko-chan a half-human or a half-ghoul?"
At this moment, Eto asked curiously.
"Let me see."
Byakuya was curious as well.
He gently turned little Aiko over, and with his Mangekyō Sharingan, he could easily tell whether or not she had a kakuhou.
After a careful observation, he discovered that it wasn't just a question of whether she had a kakuhou, rather, it was that she simultaneously possessed all four types of kagune.
Rinkaku, Koukaku, Bikaku and Ukaku; these were the four kagune types.
The vast majority of ghouls however, were born with only one type of kagune.
Very few ghouls were born with two kagune. The only known cases so far were Hinami Fueguchi and Mayu, both had inherited two types of kagune from their parents.
And the only one who possessed all four types was Shikorae Rio in the original story, a genius among geniuses, who due to successive tragic events ultimately became mad, broken, and twisted.
But now, a second individual to possess all four types of kagune had appeared, more precisely, a half-ghoul: Uchiha Aiko.
Although Byakuya wasn't entirely clear on the genetic mechanism behind possessing all four kagune, he figured it was most likely inherited from Eto.
Through cannibalism, Eto had absorbed many kakuhou and long since acquired all four kagune types.
Of course, originally Eto only had one kagune, an Ukaku and the others were all obtained later through cannibalism.
To be born with four kagune types, Aiko and Shikorae were basically the only two 'peerless prodigies' in existence.
And being a naturally born half-ghoul as well, that made two in total: only Aiko and her mother Eto.
If nothing unexpected happened, Aiko would also inherit Byakuya's Sharingan. As for when her eyes would actually awaken, that was anyone's guess.
