Manga that get axed dont get official "axed" annoucements, theyll just say its complete. But a shounen manga completed at 36 chapters with low sales is a good indicator of what happened...
The intentional homage to Crying Freeman and Showa Ultraman shows are awesome, but yeah, a bit 2edgy4me. Still, 36 chapters of this would be a decent read, even if it gets the typical axed ending.
