Basically, a Kuroko's Basket fanfic in which the OC is Kuroko's older brother. 

The main character, Akihito Kuroko is an aspiring actor with a blessing for acting. As a matter of fact, while usually extremely slow to the uptake when it concerns himself, his skills at impersonating others are out of this world.

-Akihito is a year older than Kuroko and the GOM.

-I don't plan on making him attend Seirin or any of the GOMs' school for all it matters.

-His and Tetsuya's relationship is a bit strained from Tetsuya's identity as a shadow.

-Akihito can actually be considered an antagonist to some degree lol.

-Akihito has some stalkerish tendencies which he is aware of but doesn't wish to correct.

To every Light its Shadow.

But who wants to live in the Shadow?

«I don't care if they're geniuses or prodigies. Break them and they're all just trash.» 

He tilted his head aside, his eyes at lost for a second before his irises flickered with amusement. His thin lips gently curved up into a ghost of a smile, his eyes crinkling.

"Mhm, whatever you say, Mako-chan."

"A Shadow, you say," the taller blue head reiterated. His words slow and voice mellow as each syllable rang in the silent room that was the kitchen. The male's head was gently tilted to the side and his usually dazed demeanor was completely replaced by one of incomprehension.

The younger nodded, mutely taking a sip of his cold water before readjusting his gaze on the older lookalike.

"I—" the blue head paused, searching for his words as the crease between his brows tightened. "I do not understand why you would go out of your way to disappear," he stated, his thin lips tugged down.

Gold and blue met for a silent conversation before the younger of the two looked away. "Akashi-san said I would be able to play," he confessed.

"So? To play you would give up your presence? Become something less than the masses?"

"Akihito-onii-san, don't say it like that."

"Then what, Tetsuya? Aren't you disregarding yourself entirely if you take his offer? What's so great about basketball that you would give up your self—"

"I'm not giving up!" Tetsuya interrupted, abruptly standing up. "I— brother I love basketball, being part of the first string is a dream, mine," he whispered, sitting back on the wooden chair and regulating his breathing.

Akihito gripped his hand underneath the table, his sharp golden eyes squarely stared at the youngest's despondent face, obvious contempt and disappointment flickered through his eyes before he released a silent sigh. "I am so very disappointed in you, Tetsuya," he blandly confessed.

The younger's head whipped up to meet the older's gaze as a flash of incredulity coursed through his eyes. Disappointed? Akihito was, disappointed in himself for chasing his dream?

Tetsuya's blank face broke, revealing an ugly smile as he weakly exhaled. He thought he would understand. He thought he knew him. He thought they were family, brothers. Was that only him?

"Disappointed," he murmured, voice barely audible and echoing against the white walls of the kitchen. "I thought you would support me Akihito-onii-san, that you would understand—"

"No, it's you who doesn't understand Tetsuya!" Akihito flared, losing his trademark composure and exchanging his lackadaisical self for violence. "You should know better, I for once thought you did."

Tetsuya scrunched his nose in distaste, huffing before biting his lower lip, a flicker of incertitude in his eyes. "I'm going to my room," he said, standing up from his seat and walking to the door.

Akihito didn't utter a word, merely heaving a sigh. His previously enraged face gradually morphed back to its usual blankness, leaving behind no trace of their talk. He blinked once then twice before his eyes flashed with a knowing light.

He took his phone out, accessing the note application, his mind went off-topic as he took some distance with his previous self and carefully recorded his emotional state seconds before.

His golden irises slightly dulled, his hand carefully drew his thoughts.
