I love the visuals in this manga so much. The shadow-Kujirai symbolizing Kudou's memories gets me every time.
I also love Generic Terra just always being visible in the sky. It seems like no matter where you are in Kowloon, if you can see the sky, Generic Terra is always there, you can't escape it.
By the way, if Kudou is also a double, then his memories of the old Kujirai are not his either! So he's holding on to a grief that isn't actually his! He might have more in common with the current Kujirai than he thinks.
The way this series plays with personal identity is great.
