@radiohead Yeah, I'm pretty sure he is. We know Ariko's dad is one of those guys, so it's probably Siromakur.
It's worth noting that the cover page mirrors the cover page to chapter 265, showing Tsurumi's family.
I also think that Wilk's plan is more realistic, but his priorities clearly changed. From Kiroranke's perspective, the people he grew up with would have to abandon their homes and make a long trek to Hokkaido, and many of them would probably just never go. The same is probably true for the Karafuto Ainu. Wilk was essentially picking his new family over his (and Kiroranke's) old family. Though it's a little sad to think that Kiroranke, who married an Ainu woman and had children, never had the same thoughts. To be fair, his plan was independence for everyone, but he doesn't seem to have given any preference to his own family. Also, it's funny that the thing that cemented in Kiroranke's mind that Wilk had changed is the fact that Wilk didn't just kill him..
This chapter made me think more about the Wilk/Sugimoto parallel. Wilk wasn't a soldier, but he was part of a violent revolutionary movement and was so inured to death that he could slit the throat of a comrade to protect the group. Then he met Asirpa's mom, who helped him feel human again and refrain from killing, just like what Asirpa does for Sugimoto. Meanwhile, Kiroranke never stopped being the revolutionary involved in the assassination of the Tsar and a freedom fighter for his people. He never let himself feel at peace like Wilk did, and he thinks that Wilk gave up the fight.
It's nice to see them explicitly state what the Kiroranke/Wilk rift was about. It had been heavily implied, but this made it clear. I'm still confused about Sofia's part in this, though. She's still a revolutionary who wants to overthrow the monarchy. I suppose her group believe that creating a Far Eastern Federation would give them a base of operations, but she must have realized by now that Wilk and Kiroranke's goals were independence for their people, not revolution in Russia, and while they'd want to protect their land from Russia, they probably weren't going to help overthrow the Tsar.
There is one thing I didn't like about this chapter, though: the implication that Kiroranke loved Sofia. It just feel unnecessary. He already had reason enough to oppose Wilk's plan: wanting freedom for his people, feeling like he's in a permanent state of war against Russia. Making his love for Sofia one of his motivations just undermines the ideological differences between him and Wilk. I can accept him loving Sofia, but not as a motivation for fighting for his federation, especially since his goals ultimately conflict with Sofia's anyway. Plus, I wish they could have just been friends. I know Sofia loved Wilk, but they didn't need to have a love triangle. In a series with so few women, it's too bad that the women's roles often involve being love interests.
Well, that was a big comment dump. This was a great chapter overall, to make me want to talk this much. And that's not even getting into Tsurumi's comments about goals and Tsukishima's meaningful gaze. Plus, Kiroranke is one of my favorite characters, and it's cool to see him still be relevant from beyond the grave. I'm used to dead characters quickly being forgotten and becoming irrelevant, and I even though that that was the case for Kiroranke, so this was a pleasant surprise.
