These last days I had been tied on bed with fever, thankfully now I'm gettin better, but during my feverish thoughts, out of sudden I started to think about Shusei Kagari, and my heart broke to pieces.
If you think about it, Kagari was the unluckiest one of the Division 1. Think about it: he was confined to a rehabilitiation facility since he was five years old,
being separated from his family at such young age and spend the rest of his life completely locked away from the outside world, his only friend being a boy who attempted to escape and later got killed for it. No doubt all those things made him resent the Sibyl System: they basically stole his freedom and his friend; on the other hand, his isolation of the world may had been a factor of why he developed this childlike personality that made him so adorable, and yes, innocent in a way, but not naive.
And then Kagari is released to become an Enforcer. Imagine how must had been for a kid like him with no experience in the outside world to execute someone for the first time with the Dominator, uff, I bet it may had took Kagari a while to completely adapt to his new job as an Enforcer...but then, Kagari realized that, for the first time, he wasn't alone anymore. The Division 1 became his new family: Masaoka as his new surrogate dad, Shion as the cool mom/older sister figure, Yayoi and Kougami as his older siblings who keep him in line and teach him new cool things, Ginoza who despite his actitude acts like a protective mom, and now, Akane, who's his new friend whom he can drink with and have fun. There you can see a reason that may had prevented Kagari of turning completely bitter and apathethic towards his job because it's connection to the Sibyl System: his love for his new family that became the Division 1.
But then, Kagari gets executed by the System itself, and worse of it: given his sarcastic smile and last words, it's very likely that discovering the truth of the Sibyl System left Kagari completely shocked and also....angry, in a way. So at the end, this was the System that had depraved him and so many others of normal life for what they decided it was a "latent criminal"? A bunch of brains? So a collective of people was controlling other people's lives? They were the reason why he had to live like he did, weren't they? And not only that, the System is now pointing at him with a Dominator, ready to end his life. At the end, the System controlled completely Kagari's life, and even decided his own death. Despite he didn't did anything wrong, save being diagnosed as a "latent criminal".
And that's what breaks me about Kagari: he was the one who lost everything to the System. He lost his freedom, his normal life, and then when finally it seemed he now had a new family and a job, he got that stolen by the System because he "saw too much". And to make things worse: Kagari, who was always loyal to his friends, got registered by the System as a criminal who escaped - the complete opposite he did. He will be officially remembered as a "traitor" when he never betrayed his team. And that's fucking sad.
And that's why I think Kagari was the member of the Division 1 who had the most tragic fate. I mean, all of them suffered, but at the end, they all kept going - happy or not - with their lives in a way or another, and Masaoka, who died as Kagari, at least died knowing he saved his son's life, so his death wasn't in vain. But Kagari didn't had that: at the end, the System overrode any kind of evidence about his last actions and moments, and officially portrayed him as a betrayer who ran away to hide the fact they killed him. Only Akane knows the truth, but the rest no, even if some of them may have their suspicions.
