Magazine scans of ch.01~03 out of 5. Prototype Onideka (?), the first chapter has a lot similarities but there's no urgency later, and thus leads to different developments.
Killing Bites and Dororon! Okuni-chan are serialized on this magazine, the second one was a cool find (it isn't scanned currently).
Most changes are offscreen between panels.
