This is 882 words, discluding the author's note, pretty short but it's like a prologue.
The first time he met him was, uneventful, so to say, as he was just a week old and he was twenty.
His dear sister, Kuroko, now Akashi, Shiori often brought his nephew to see him.
He introduced young Seijuuro to the wonders of basketball, often letting him watch groups play at his gym.
His name, is Kuroko Tetsuya, he is six years younger than his sister, Akashi Shiori, who married Akashi Masaomi.
He was named the heir to the Kuroko Corporation, a powerful company who owned many sports buildings worldwide, from dojo's, to pools, to training centers.
He was many things, but to his nephew Seijuuro, he was Tetsu jii-Chan, his favorite person, other than his mother, to spend time with.
"Tetsu jii-Chan! Tetsu jii-Chan!" A young red head waved enthusiastically, his hand holding onto a teal haired woman.
Kuroko Tetsuya turned his head around and smiled lightly as he greeted his nephew, "hello Sei-Chan, you seemed to have grown bigger since the last time I saw you", he said to the four year old.
Seijuuro puffed his chest in pride, "of course, Jii-Chan! One day, I'll grow even bigger than you!" He exclaimed. Tetsuya chuckled, but inwardly, he pouted as it will probably be true that Seijuuro will indeed grow taller than him.
"But then Sei-Chan won't be able to piggyback ride on jii-Chan anymore."
Seijuuro frowned, thinking of a solution, before he brightened, "them I'll have jii-Chan piggyback ride on me!" He said, happy with the solution he came up with.
Tetsuya chuckled with his sister. "Nee-sama, is there a reason on why you visited?" He inquired. Shiori smiled sheepishly, "Ah, Yes, Tetsuya, Masaomi and I need to go on a business trip, I came asking if you can take care of Seijuuro for two weeks."
Tetsuya smiled, "I'll gladly take care of Sei-Chan." He said before turning to Seijuuro, "what do you say, Sei-Chan?" Seijuuro beamed,
"Of course!"
"Jii-Chan," Seijuuro Said, holding his uncle's hand, "hmmmm?" Tetsuya answered, recording the results of a swimmer's muscle injuries' healing.
"What are they doing?" Seijuuro asked, pointing towards a group of men bouncing a ball while laughing.
Tetsuya looked up, and smiled at seeing the familiar faces of his friends. "Those are my friends, Sei-Chan, they are playing a game called basketball, do you want to try?" He answered. Seijuuro nodded, Tetsuya smiled and told the swimmer that his arms are healing well, before bringing Seijuuro to the group of men on the court.
"Kagami-kun," he called, a man with dual colored hair and split eyebrows looked up, and grinned as he saw Tetsuya, "Oh, Kuroko! 'Sup? Thanks for letting us use a court, by the way."
Tetsuya smiled softly, "it was nothing, Kagami-kun, anyways, I would like you to meet someone." He said, as he lifted Seijuuro into his arms.
"This is my nephew, Akashi Seijuuro, Sei-Chan, this is my friend Kagami-kun." He said as he introduced the two to each other.
"My name is Akashi Seijuuro, nice to meet you," Seijuuro bowed. He felt a hand ruffle his hair, "haha, so this is the nephew that Kuroko always brags about, with your manners, you must be Shiori-San's kid." Kagami laughed.
"Oi! Kagami! Come on!" A guy with black hair yelled, Kagami turned around, "got it!"
He turned towards them apologetically, "sorry, man, Izuki-senpai's calling, Captain's gonna be angry is I stay here for too long."
Tetsuya nodded in understanding, Captain was pretty scary in clutch mode. A idea appeared in his head. "Kagami-kun," he called, "why don't Sei-Chan and I join you? I just finished the last of the important paperwork, I have time to spare, and I'm pretty sure Sei-Chan will like playing, right Sei-Chan?"
Seijuuro nodded excitedly.
That, was when Seijuuro fell in love with basketball.
Seven year old Seijuuro sobbed into his uncle's chest as he watched the funeral of his beloved mother.
Tetsuya himself was also upset, his blue orbs wet with tears, beside him, Kagami was saying his prayers and blessings for the young woman.
Tetsuya was reminiscing the last words his sister said to him;
"Tetsuya, I know that Masaomi is not a bad person, but I fear that my death may drive him over the edge." The teal haired woman said, "what do you mean, Nee-sama?" Tetsuya had asked.
Akashi Shiori smiled softly, "I am afraid of what he might do to Seijuuro after I die, I don't want Seijuuro to be pressured, I want him to live his life as a normal man, that's why," she said, turning towards her brother, "that's why, I need you to watch over Seijuuro and make sure to stop Masaomi if he does anything drastic."
Tetsuya hesitated, not because he doesn't want to, but because he wasn't sure if he can do it, Shiori looked at him with pleading eyes, "please, Tetsuya, promise me this."
"I—."
"Please, Tetsuya"
"I... I promise."
There was no way he could've said no, so now, all he can do is try his best to protect Seijuro.
