Chapter 1: Sukunii

Chapter Text

Sukuna took a long drag of the cigarette between his lips, then he took out the flame on the very same wall he's leaning against with before throwing it on the ground, Mahito looked up from her phone frowning, 

"What's up?" She asked,

Sukuna pushed himself off the wall and straighten, stretching his thick arms up above his head before grunting his reply,

"I'm off" 

"Off to where? Aren't we meeting Getou at the arcade" Mahito crossed her arms around her chest, giving Sukuna the look she use to get their fool schoolmates to do shits for her, that didn't work for Sukuna, 

"I didn't agree on anything" he simply replied as he began walking,

"B-but! You can't just leave me!" Mahito yelled indignantly, stomping her feet on the ground,

"Oh darling, trust me, I can" he smirked when he saw red blooming on her cheeks as she ground her teeth in anger,

"Sukuna!" She yelled at his retreating form, 

Sukuna waved his hand not bothering to look at her. 

 

"Yuuji" Sukuna called his younger brother's name, the boy turned to where the older is before bouncing towards him,

"Sukuna!" He happily calls back, Yuuji stopped a few inches away from his older brother, looking up at him expectantly,

"That's Onii-san for you, brat" the older flicked the younger's forehead before leaning down planting a soft peck on the same spot where he flicked,

"Sukuna stop!" Yuuji tried to push his older brother away but Sukuna already caught him in his arms and already peppering him with soft kisses all over his face,

"What?" The older asked innocently stopping abruptly from his ministrations,

"Stop doing that! I'm not a child anymore" the younger complained, pushing harder but the older didn't budge, not a single bit, 

"Yeah? But you are my baby Yuuji and you're not complaining this morning" Sukuna finally took a step back but his arm stayed around his baby brother's shoulder,

"That's different! and stop calling me baby! I'm already 15 it's embarrassing" Yuuji whined,

"Doesn't matter if you're 15, 20, 25 or 30, you are my baby" Sukuna teased, smirk growing as the red on Yuuji's cheeks starts to spread down to his neck,

"I hate you" the younger turned his head away from him, face scrunching into a displeased pout, Sukuna raised his hand to poke at his chubby cheeks but Yuuji just swatted the invading hand away, 

 

He's pissed, how cute

 

"Okay, sorry, what will this Onii-san have to do to be forgiven" he asked, rubbing circles on his brother's back, Yuuji tried to hold his angry facade a little bit but the offer is just too tempting, so he gives in, with a sulking voice he began,

"The manga I'm reading-" 

"Let's drop by the bookstore on our way home?"

"And then there's this limited edition pudding-"

"From the combini or the sweet shop?" 

"From the combini near the station" 

"Okay, anything else for this dear little brother of mine?"

"Hmm for dinner I want some karaage and you have to wash the dishes afterwards" he knew he's acting like a real spoiled brat right now but this I just a small compensation for all the teasing from his friends he has to endure whenever they witness Sukuna's shameless doting so he better take everything Sukuna has to offer,

"You're such a spoiled brat, whatever let's get going now, I have to marinate the chicken" Sukuna grabbed Yuuji's bag and sling over his shoulder before he grab the younger's hand and starts walking, Yuuji stopped abruptly halting the older's movement as well, 

"What now bra-"

Yuuji tipped on his toes and plant a chaste kiss on his older brother's cheek, 

"Thanks Onii-chan" Yuuji spoke with a small shy voice and it instantly melts Sukuna's heart,

"Let's drop by the mall on our way, lets get you that shoes you've been talking a lot to Chouso" 

 

He's going to spoil his baby brother rotten today.

 

"So, where's your boyfriend?" Hanami asked, as she tuck a few stray black hair behind her ears, Mahito's face scrunched, annoyed at the fact that first, she and Sukuna aren't dating yet, second why does Hanami have to bring him up,

"Dunno, he ditched me"

"Hmm, you really have to reconsider your life choices Mahito" 

Ugh, why does she have to act like the voice of reason in their group,

"Isn't that Sukuna?" Jogo interjected, nodding Infront of him, Mahito followed his line of sight and lo and behold Itadori Sukuna, that fucker-

"Who's that with him?" Jogo continued,

then she noticed a smaller figure walking beside him, Sukuna holding the other's hand, okay fuck..

"Oh, isn't that his baby brother?" Getou joined in, 

"He has a brother?" Mahito asked bewildered,

"Yeah, I caught a glimpse of him once" 

"Glimpse?" 

"Yeah, He's really protective of him"

"How sweet" Hanami cooed,

"I knew he has an older brother, but never heard of the younger one-" Jogo spoke,

"Wait, he has brothers?" Mahito asked once again,

"Aren't you two dating?" Hanami raised a perfect eyebrow at her,

"He-"

"Well, I'm not surprised he didn't tell her about his brothers, especially his baby brother look he even ditched her for his baby brother-" 

"You fucking maggot! I'm going to rip that grin off your face Getou!"
