"Saiki talking to the reader or other characters through telepathy"
"Saiki talking using mouth"
'Saiki or any characters thoughts'
As the door bursts open, a mischievous grin spreads across Kusuke's face as he eagerly intrudes into Kusuo's bedroom. The vibrant pink-haired lets out an irritated grumble, displeased by the lack of privacy and consideration from his siblings.
"Can't you freaking knock??" Kusuo complains, feeling frustrated that his reading time is interrupted.
With a playful smile, Kusuke announces, "I've created something!" He keeps both hands carefully concealed behind his back. "And no, it's not a weapon this time, I promise."
Though, instead of getting mad, he inwardly sighs and chooses to observe the unfolding situation. He contemplates using his telepathic abilities to see what Kusuke is hiding, but decides against it, intrigued by the prospect of being surprised for once.
Kusuo's interest is piqued as he listens to Kusuke's words, hoping that perhaps this invention will be something truly beneficial and not just another weapon.
"Okay, so... this thing is actually for Y/n. Not a weapon, I swear to God-KUSUO PUT YOUR HANDS DOWN-"
"What is it?" Kusuo scowled, not entirely concealing his curiosity.
Kusuke then displays the invention in front of his brother. "It's... A cat headband?... An accessory?" Kusuo asks, confused by the sight of a fluffy cat headband on Kusuke's hand.
Kusuke then explains, "Nope! What you see right now is a power control. I know Y/n can't completely control their abilities. If she wears this, her power will not burst suddenly or teleport her somewhere."
Kusuo remains quiet.
"So, what ya think?!" He asks for his brother's approval.
"The function is nice..." Kusuo tells his opinion.
The older brother thought he did a great job.
"However...
You really think I'll let her wear that out in public?"
Now he is really mad.
"Change the design. Or else."
Before Kusuke can reply, he gets teleported back into his lab.
･ᴗ･
"Kusuke!!! It's so cool!!" The youngest hugs the oldest.
He chuckled at your reaction. "Special for you. There are some features, you can call me anytime just by clicking the gemstone-"
"shut it."
"Yea..."
You looked down at the gold bracelet with a gemstone in the middle and touched it. The color suits you well.
But you don't know the real reason why your brothers give you it. It's probably just a random gift. Or an early birthday gift? You decide to ask.
"But why are you giving me this? My birthday is not-"
"Hush, my little cookie. Can't your siblings be nice and give you a gift? Not even a thank you is heard." Kusuke frown.
"Ah- right... Thank you." You tiptoe and peck Kusuke's and Kusuo's cheek.
The two brothers blushed slightly at the sudden affection they received.
Kusuke let out a small chuckle. "Anytime" A smile plastered on his face.
On the other hand, Kusuo keeps his stoic expression. For once, Kusuo is grateful because no one gets to know his fast heartbeats and how his mind is talking gibberish.
･ᴗ･
At night. Kusuo keeps turning around on his bed, unable to brush off his thoughts. He groans and sits up.
He finally set up his mind and teleport to his brother's lab.
He finds himself inside a dark room. The only source of light is the big computer screen in front of him. And there sits the older brother.
"hey..."
Kusuke perked up at the voice and turned his chair around. "Kusuo? What's up? It's in the middle of the night and you are here. It must be something important."
Kusuo looked at him and let out a small sigh.
"Do you... still have the cat ear accessory?"
The older brother looks at him with a surprised look. "Uh, yes... I still haven't thrown it yet-"
"Give it to me" Kusuo interrupted.
Kusuke can't help but smirk. "Oh? Why is that?" He teased, knowing the reason why.
Kusuo groans at the question. "Just give it."
"Alright alright, fine." He finally surrendered. The blonde takes the item out of his coat and walks forward.
"Here, better use it for good."
Kusuo scoffs at his statement. "I'm actually going to burn it."
"Wait what-" before Kusuo can hear the full sentence. He teleported back into his room.
He looked down at the item and put it inside his drawer. Hoping no one would open it.
Kusuo lay down on his bed with a relief sigh. He hoped he could see Y/n wearing it someday.
Though, it's better to keep it to himself. Or else Kusuke would force you to wear it.
