Dr Stone agere headcanons part 2
~Kohaku's a pet regressor, specifically a lion cub.
~The most energetic little out of the group.
~Easily distracted when regressed, and constantly looking for something exciting to do. Definitely was made a backpack leash by Yuzuriha just so her caregivers could keep an eye on her better and not have to call someone to go and chase her down
~She was probably so extremly happy when Tsukasa joined because she finally had another regressor who doesn't mind rough housing!
~Ruri probably really enjoys getting to spend time with Kohaku in 'baby lion mode' because it’s one of the few times Kohaku will let herself be taken care of. Ruri trying to tame her baby sister’s wild hair with a brush that nine times out of ten only gets her the result of angry kitten teeth chomping on her.
~Chrome has gotten used to her antics, especially the whole, ‘lion cub suddenly jumping on top of you because she's excited’. (Senku did not get the memo and the first time this happened ended up with the two of them both face planted in the dirt.)
~Also please consider Tsukasa and her sun bathing outside, curled up together for a nap and sharing the pelt that Tsukasa wears as a blanket. Someone has a photo of this it is 100% percent used as black mail at some point in time.
~Chrome definetly had a working theory as to what was going on with the others, that may or may not have included some form of sorcery back before he met Senku.
"What's wrong with Kohaku?”
Chrome just shrugging and going: “yeah she does that sometimes.”
Chrome: “She does what now?!”
~Definitely very open about it and very intrested in learning about the human brain and its way of coping through difficult situations.
~He's regressed a couple of times when Senku arrived, age being around a toddler.
~Sometimes Senku will set up kiddo friendly science experiments for the two of them to do together.
~He’s gone on a lot of ‘adventures' with Ryusui whenever the captain is regressed and looking for a playmate as they both love exploring
~Kinro for the life of him would never admit to regressing. Ever. Ginro only knows because, well it's his brother and of course he notices when something is off (He didn't realize at all actually for the longest time. And even then it was only because Kinro brought it up, apologizing for being so off and that he felt all fuzzy and weird and that it kind of scared him. Which in turn freaked Ginro out because his brother and the word scared do not go hand in hand)
~I like to think that as much as Ginro would like to be babied and small and forget about every single scary adult problem he genuinely can't slip fully or stay small often. More of an age dreamer.
~And Kinro doesn't understand why anyone would want to purposfully feel like that, powerless and scared (due to the fact that his regresion is usually involuntary and triggered by stress and high emotions.) In fact most of his recollection of regressing once he had a name to it had been on really bad days where his brother would try his best to act as a 'caregiver.’ So yeah no, he doesn’t want to play, or run around with the other littles. He rather forget that was ever a thing his brain forces him to do.
~Kinro's an okay babysitter if he has to. Not the best with kids but not the worst. That honor he would like to give to his brother who has insisted that he is a great babysitter and that kids love him, only to lose the little he was meant to be watching in the first 15 minutes and force Kinro to babysit instead.
