#exponential decay

Fandom-wise I was way more interested in the kids in the previous generation (the SSS Trio) and wanted a character to explore them by being another student at Jujutsu High during that generation. Second, I wanted Geto's family to be more explored because we know very little about the members who are not Mimiko and Nanako so Michi was created around the concept of someone who defects from Jujutsu High to join Geto's family, and therefore interacts with both Gojo and Geto.

The second reason he is the easiest, is because so much of him is modeled after Gojo his character voice is roughly the same. Michi dialogue is the same as Gojo dialogue, it's just phrased more politely. They are both characters who say whatever comes to mind and often have trouble perceiving other people's emotions in reaction to what they say. Gojo is the easiest character to write, so Michi who is his double in the story, the moon to his sun essentially comes naturally to me too.

Michi is just also once again the character I have put the most thought into, and planned out his arc. I know him when he was seventeen years old as a student in Jujutsu High. I know him and how he interacted with Geto's family for those ten years he lived with Mimiko and Nanako. For example, Michi never believed in Geto's dream, he only wanted to remain by Geto's side because he believed in some small way that he could course correct Geto. One thing he often did was intervene and try to calm Geto down whenever Geto tried to attack children who were not jujutsu sorcerers. Michi also believed that Geto is the only person powerful enough, to have stood a chance of achieving his goal of just destroying Jujutsu Society point blank and forcing them to rebuild.

(Michi is the alternative to Gojo, if he had Gojo's powers he would have just slaughtered the elders and let someone else take control from there, which is pretty extreme but Michi's belief is child abuse is the utlimate evil that can never be tolerated and should be punished and made so it can never happen again. An institution that exists at the expense of children cannot be reformed in any way, only destroyed. Basically Gojo thinks any radical change wouldn't stick and wants to make the next generation strong enough to take power and replace the elders, Michi has no patience and wants them gone now).

Then, in the third stage of his life post Geto's death, Michi basically has lost his purpose and place of belonging so he finds himself again in creating a place that is safe for other lost children like Mimiko, Nanako, Junpei.

Like, see it's easy to write an OC when you have this much of them planned out down to the smallest detail. When you have their character arc, flaws, and where you want them to end up at the end of the story all mapped out. (Ideally, Michi will eventually be a teacher again b/c working with children is what his character centers around). 

The OC that was the hardest for me to write was Ito Rie from Werewolf, and that is because they're actually not my OC originally. They belonged to a friend who was basically like "can I create an oc for your universe? Okay, well she's a really dirty kid, she used to live with her grandma but now she's a runaway kid, she cuts things with her kendo sword she swings around. Michi found her on the side of the road and gave her food. And also she's a lesbian. And also I think she'd be friends with Mai."

They did not really give me a lot of details beyond that so I had to spend a lot of time asking her questions, and then giving her ideas for what Ito's backstory could be, and how she became a curse user in the context of the story, and what happened to her grandma that caused her to be homeless and continually on the run from other people. It was all those questions I asked my friend about this character that made Werewolf come about, which was essentially Ito Rie's origin story and how she became a runaway.

The other thing that made Rie tricky is I decided to do the possession with Noranso plotline, which meant I had to write a character who was posessed but this was a twist and not obvious right away. Which means I essentially have to write a character acting very noticeably off (hence why she goes by weird girl) and unsettling for a girl, and at the same time like, idk have her have dialogue, have her interact with other characters, have her do stuff without giving away the twist too early. It was just a weird line to balance. The other thing is that Ito is posessed for most of the story, so I had to establish what Possessed! Ito acted like and what Normal!Ito acted like. The Ito we were talking with for much of the story is not the real ITO! TM so I had to find a completely different character voice for pre-possession ITO! and also she only appears really briefly in her first person segments so she had to be someone unique and striking like. You had to get a grip of what Ito was like before she was posessed within that limited screen time.
