I've had this really interesting headcanon with SF-A2 Miki and Utatane Piko.
Miki actually created Utatane Piko!
Miki is a genius, mad scientist android, and a robotics teacher, who is colleagues with Hiyama Kiyoteru. Kaai Yuki is her favourite student from outside her class! And she is best friends with Nekomura Iroha, often assisting Iroha with her equipment.
Now, on to the interesting part. Miki wanted to make an android for the fun of it! She just wanted a helpful partner to guide her students with her.
Originally, Piko was supposed to be female. But Miki scrapped that idea last minute. Instead of changing his model, she just changed the sex programming, which quite literally makes him trans-coded! And also the reason why he kinda looks like a trap...
This does technically make Miki his mother, but she refers to themselves as siblings because Miki did not wanna feel old(Even though she's a robot herself!). And everyone agreed to refer to them as siblings.
Miki named him Piko because-
- (A cover story)- His USB tail utilizes pico-technology, which is why his tail moves independently.
- (Actual reason)- Because he looked so much like her favourite artist, Piko! And the reason for his gender-swap.
Moving on-
Miki is very affectionate with Piko, often spoiling and even babying him, which genuinely confuses Piko... Because why is she infantilizing him? He's just as intelligent as she is, yet she's always squishing his cheeks and giving headpats...
But Piko does deeply respect her, however grumpy he may be... She is his creator after all.
A little funny extra-
Piko is afraid of children because they're messy, chaotic and destructive. And he's aware that he's a fragile piece of tech...
Yuki? Fine, she's well-behaved, most of the time...
Ryuto(Gachapoid)? An actual, living nightmare...
So, there's that. Your thoughts?
