( 𝟏 ) SENKU + HIRO. I’m not sure if you’re familiar with Dr. Stone, but please know that Senku and Hiro could get along fantastically. To put it simply, Senku is a teenage genius, similarly to Hiro, with a strong passion ( and mind ) for science. I’m sure you can see where I’m going with this, but with Hiro’s skill in robotics and Senku’s scientific mind, they’d play off one another really well. I can imagine the two of them staying up to the early hours of the morning working on projects together, inventing and experimenting, coming up with incredible ( or incredibly dangerous ) ideas and using their combined knowledge to achieve new things.
As Senku was miles ahead of his peers in terms of intelligence, he’ll be able to relate to Hiro greatly in the sense that they never really fit in with people their age ( well, Senku did have Taiju and Yuzuriha, admittedly ), so to that end he won’t even bat an eye at Hiro’s age or the fact that he’s entering college several years early. He’s not really one to make judgements based on anything like that, as he vastly prefers logic despite having the biggest heart going.
( 𝟏.𝟏 ) Luckily, as Senku can fit in easily with a modern verse / Hiro’s canon verse, we have a few options in terms of plots! Senku canonically visits a lot of different places growing up, so it stands to reason that he could end up in San Fransokyo for one reason or another, or Hiro could potentially visit Japan. I can see Senku really respecting Hiro’s opinions and skills, forging a sort of kinship with him and their shared love of science.
Senku could potentially offer a hand in the development of new equipment or chemicals with Big Hero Six, if he ever learned of their existence!
( 𝟏.𝟐 ) This one is pretty dependent on your knowledge of Dr. Stone’s universe ( no pressure whatsoever! ), but it could be pretty fun to explore something set after the petrification of humanity and seeing how Hiro fits in with the Kingdom of Science, especially if we developed something where Hiro and Senku knew one another ( however briefly ) before the petrification. The idea of Senku having yet another science buddy alongside him to help rebuild human civilisation is a really wholesome one and I’m into it. Hiro would undoubtedly be in charge of engineering and helping the Kingdom of Science build machinery and modes of transport, given his expertise!
( 𝟐 ) HARUKI + HIRO. With your KNY verse in mind, I feel like my KNY OC, Haruki, and Hiro could also get along really well ( if you’d like to know more about them, feel free to hit me up and I’ll happily rant away for ... a while ). Similarly to Hiro, Haruki is an inventor at heart, something they dedicate themselves to fully after retiring from their status as Pillar. They’re still learning how to fashion weaponry to a high standard, so there’s every chance that they could learn a thing or two from Hiro when it comes to crafting swords in order to expand their repertoire.
I can imagine Haruki naturally, if not unintentionally, assuming an older sibling figure to Hiro, being somewhat teasing but very supportive and attentive. They have a tendency to gravitate towards those younger than them, likely as they seem them as more vulnerable and in need of support/protecting, something they unconsciously carry with them after they lost their sister at such a young age. They certainly don’t seek to replace her, but they have a soft spot for kids and want to see them become the best person they can be, which will naturally extend to Hiro over time!
( 𝟐.𝟏 ) I imagine Haruki and Hiro’s shared enthusiasm for weaponry and forging them is what brings them together in the first place. Haruki stubbornly sought out the hidden Swordsmith Village ( going as far as requesting Oyakata-sama allow them to visit ) after losing their leg and retiring as they were desperate to continue being of use to the Demon Slaying Corps and wanted to learn how to forge weapons for their fellow Demon Slayers. This could provide a decent meeting point for Hiro and Haruki! As for where to go from there... Haruki could learn some tips and tricks from Hiro, offer to accompany him places to collect any materials he might need etc etc, share their own ideas and inventions with him... Anything beyond that is totally up to where plotting might lead us if you’re interested!!
