Senku as a dad.
Senku would make small child safe chemistry items for his son. His son barely a year old but crawling early for a 5 month old; it is not surprise to everyone in the village since he is the son of Senku Ishigami and got his smarts and intelligence. He named him Akira Byakuya Ishigami, he now understood how his dad felt when he saw Senku hit milestones because he was very proud of his son. His wife Y/N was just as proud of Akira for learning to crawl early but also worried as he always crawled towards the lab knowing that was where his dad was all the time. Senku had to make a door so his son didn’t crawl inside.
Senku was making blue prints for his son’s toys when he heard his son crying outside, Senku got up and opened it” Akira, you know you aren’t suppose to crawl away from Mommy…” He looked down at his son then picked him up Akira snuggled into his chest, hiccuping from crying” you’re going to be the death of us, kid. Fine, you can stay with me while I work. But no touching anything dangerous.” He said, carrying Akira back to his workbench. He sat down with Akira on his lap, keeping a firm grip on him as he resumed sketching, Akira watched his dad sketch while sucking on his hand.
Senku chuckled at Akira’s fascination with his work, finding his son’s curiosity adorable. He held up the sketch of the chemistry set for Akira to see, pointing to the different beakers and test tubes" look at this, buddy. This is how we make science happen. You’ll be able to do this someday too” he said, using his free hand to gently bounce Akira on his knee. Akira cooed and babbled in response, still sucking on his hand but now watching Senku intently. He looked at the flask in the picture then at the one on the table” ince” as he tried to to say science but couldn’t since he was still too young and had no teeth to form proper words but he was trying.
Senku’s eyes widened in surprise and delight as Akira tried to say “science”. He grinned widely, feeling a rush of pride and excitement” that’s right! Ince! Good job, Akira! You’re already learning!" He praised his son, kissing the top of his head. He picked up the flask on the table and held it up for Akira to see better” this is a flask. We use it to mix chemicals and create new things” He looked at the clear object, he touched it gently” icals” he tried to say chemicals. Senku’s heart swelled with joy as Akira tried to say chemicals. He couldn’t believe how smart his son was already, picking up on the scientific terminology so quickly. He chuckled and nodded enthusiastically” yes! Chemicals! You’re a natural at this, Akira. You’re going to be a scientist just like daddy."
He ruffles Akira’s hair affectionately. He set the flask down and picked up a beaker instead, showing it to Akira” and this is a beaker. It holds the chemicals we use” Akira said as he held the bottom of the beaker “Eeeaaaeerrr” *Senku laughed again, his eyes sparkling with amusement. He was completely enamored with Akira’s attempts to speak” close enough! Beaker! You’re getting there, buddy. You’re going to be saying full sentences in no time." He encouraged him, taking the beaker back and setting it down safely, he noticed that Akira was starting to droop a bit, his eyelids getting heavy. But he was still determined to stay awake and learn. Akira jolts awake, sitting up and whines like he was hating being tired.
Senku chuckled at Akira’s stubbornness, noticing how he would jolt himself awake whenever he started to doze off. He could see the frustration on his son’s face as he fought against sleep” hey now, no need to be grumpy about it. You need your rest, little man. You can’t learn if you’re tired." He gently rubbing Akira’s back in soothing circles. He knew that Akira was a fighter, just like him, but he also knew that his body needed rest to grow and develop properly. Akira moved so he was sitting sideways on his dad’s lap and leans into him, his head resting on his chest, holding onto his shirt and fell asleep.
Senku smiled softly as Akira settled into a more comfortable position, his little body going limp against him. He wrapped his arms around Akira protectively, holding him close as he slept. He could feel Akira’s tiny fingers clutching his shirt, even in his sleep" there we go, finally. Sweet dreams, my little scientist." He pressed a kiss on the top of Akira’s head. He continued to work with one hand, careful not to jostle his son too much. The lab was quiet now, save for the sound of Senku’s pencil scratching against paper and Akira’s soft breathing, the soft glow of the candlelight being the only light in the lab.
