Demon! Shin gives off Sukuna vibes

It's interesting you picked up on that because er... someone might have been rewatching and rereading Jujutsu Kaisen lately to do a character study of a certain thousand year old curse for future potential projects.

Now this was after chapter 2 was basically completely written so the two aren't related. However, as I was telling @akumacaron literally the other day, when I write a character, I have usually have a sense of their voice in my head (not as weird as it sounds I promise) and while working on my planning notes for chapter 3, I started to get a sense of Sukuna's voice sneaking in and I was like you're not supposed to be here.

But yeah outwardly Sukuna and Shin do have some big similarities, namely the joy they seem to get out of violence and some fairly impressive egos. However there are some big differences as well, namely Shin has something to prove and some of his behaviour is compensating for his own insecurities, while for Sukuna this isn't the case at all. I also think it's worth noting that Sukuna is a much better strategist and planner and is far less inclined to make stupid decisions than Shin.

Case in point that fight with Gojo in episode 2, where Yuji seems to suppress Sukuna after ten seconds but Sukuna later reveals in episode 6 that partly worked because he wanted to switch too. We're not given a reason for him wanting to switch, but if I had to interpret it, I'd say it's because he realised that with only one finger's worth of power, he couldn't beat Gojo and chose to wait and take stock of his options. Shin on the other hand would not have backed down (and would probably have died).

So yeah there definitely are some surface similarities and in The Demon Prince I really wanted to lean into Shin's love of violence to make him seem as awful as possible which is probably why he seems more similar to Sukuna than usual.

I will say however that if I'd written The Demon Prince with Sukuna rather than Shin, there is no way in a million years I'd have let the reader win.
