Personally, I love them.
Suzuya is one of my favorites. He’s an incredibly disturbed kid, was tortured and abused and made into a weapon, then given a second chance by an adult who showed him love and he actually responded to it. T-T
I think, now, his dependence on “what Mr. Shinohara would want” has become an crutch for ignoring his own feelings and ideas. The manga depicts him as very distressed over Furuta’s actions, yet he still tried to kill Kaneki and exhibited cruelty towards Hinami and Touka. I hope he reckons further with his past and moves ever onwards.
Arima is a fascinating character. His suicide hurts my soul. The poetic lines on how he always hated himself, who only lived to take from others, are heartbreaking. And yet…his plan required allowing countless ghouls to suffer and die, and female ghouls to be raped over and over by Tsuneyoshi. And then, what was Arima’s actual plan – for everyone to turn into ghouls? For Kaneki to be the strong leader he wanted Kaneki to be, but Kaneki was not?
Idk, what I’m trying to say is Arima is shrouded in mystery still. I think there’s a lot more to discover about him.
And while Furuta’s plan involved more outward genocide and bloodshed, Arima’s plan still relied on allowed ghoul’s unfair deaths and rape to continue. So was Arima’s plan better than Furuta’s, in actuality? Eh…I think it was, because Arima ultimately did want peace, while Furuta primarily wants to die. I understand why Arima did what he did, and why Furuta did what he did, and I mourn the actions of both (and I suspect Arima did too).
All that to say, Arima is a fucking amazing, well-developed, beautiful character. If he ever crossed into the Snk world, he, Erwin Smith, and Eren Kruger would have a lot to talk about. ❤
