Red Hood has almost twice as many Jump+ views as Neru (510k vs 270k for the first three chapters).I am way more worried about Neru than red hood just for the fact it doesn't seem to have any discussion at all
Neru is low, incredibly low. It's less than what Zipman or Kowloon's Ball Parade had.
Red Hood is high, but not enough to be safe, a bit under what Time Paradox Ghostwriter had. In the past year or so, only TPGW, Guardian of the Witch and Phantom Seer were axed with higher views. On the other hand, only Magu-chan, High School Family and Roboco lived with lower views.
Ideally, it'd need 700k-ish views by the time volume 1 releases.
If Red Hood gets a color page, or even a cover, it could gain them. The promo surrounding the first volume should also help it. But Neru would need a miracle to live.
