I wonder which of the deibu's kos are the survivors. The graph says the 5th marisa, 16th marisa, 31st reimu and 47th reimu survived. I'm wondering what order this is supposed to be in, as the 16th ko reading left to right, row by row is a wasa, the 16th ko reading both left to right and right to left, column by column are sleepy fat shits and every ko reading right to left in rows don't fit the personality of the survivors (too distracted, hyper, wrong variety ect.)
Sure, more deibus may make it to adulthood, but this isn't a complete picture. As adults, deibus will usually counterbalance themselves by pulling aggro on humans or bring down clans they manage to join. Only z-aki grade karma houdinis manage long stints as adults.
This chart doesn't really show anything relevant, because surviving to young adult age means nothing for the Reimu's, their survival will be determined by whether or not they find a mate to leech off of. Unless we assume there are entire communities of Deibu's with Marisa slaves, or that it's a mainly incestual family tree.
Interestingly, the mass of the deibu spawn makes their own deaths somewhat meaningless. If one dies, there's still a swarm of babies coming from mother deibu. Statistically speaking, ONE of them will make it.
Then there's the right half, with Marisa and Patchy. One offspring dying is far more significant than one of the deibu's, and could possibly spell the end of a generation.
So basically, the deibu is more likely to forward the population. Which is nine kinds of ass backwards.
Paste brain and scum are in a endless cycle of breeding and dying Big families have a low chance of survival because it's hard to maintain and they attract too much noise, abyusers and predator's can detect them more easy
But also that big families have better chances of one of their koyus manage to reach adulthood so they can continue their worthless life's
But for average families like neutralheads and smartheads, their numbers are always stable as this families tend to have better understanding of their reality
Yukkuri life always depend on luck, it's doesn't matter how intelligent you are or how cautious you are
Such things can help you better to survive
But as long your luck is running out, things can end up bad pretty fast..........
