For the past few episodes of Shin Sekai Yori I’ve thought that there was something fishy about Yakomaru’s plan. Now that episode 23 has aired, I am looking forward to seeing what Yakomau’s ultimate goal is and how he’s going to achieve it.
There’s no denying that Yakomaru is a brilliant strategist. His attack on the humans has so many layers that it seems almost impossible for the humans to have prepared for it. To recap, here are the different points of his plan so far:
1. Join the bakenezumi colonies through negotiation or elimination of opposing factions.
2. Minimize human resistance by poisoning them during the festival.
3. Launch a surprise attack to catch them off guard.
4. Invade the hospital in the ensuing chaos to obtain human babies.
5. Plant explosive mutants in the waterways while the humans repel the initial attack, forcing the humans to drain the channels and limit movement.
6. Unleash the akki to kill the more powerful humans.
Now here’s what I don’t understand. As of episode 23, the assumption is that Yakomaru’s goal is to kill off the humans and the kidnapped babies are plan B to turn into akki if the attack fails to eradicate the humans. Yakomaru’s plan stands little chance of success so far. His attacks only destroyed human settlements, it would be easy for small numbers of humans to flee into the wild and survive alone as Inui has demonstrated. Only one of them needs to survive in order to destroy the bakenezumi colonies. Even with the akki by Yakomaru’s side, it can only be in one place at a time, making it inefficient at eliminating the humans.
Having an arsenal of human babies may help Yakomaru legitimize his position as leader of the bakenezumi, but I question whether they will do him much good against the humans. It takes about 10 years for their powers to manifest, meaning that Yakomaru would have to deal with retaliating humans for about 10 years with just one akki. Another problem with the babies is that they might turn out to be useless. The death feedback system was built into human DNA centuries ago; the likelihood of all of the babies having it is extremely high. I’m actually suspicious of how Yakomaru’s akki is able to kill others in the first place given that Mamoru and Maria both had the death feedback system, otherwise they wouldn’t exist.
Perhaps I’m missing something, but there also seems to be another hole in Yakomaru’s plan. The humans can kill the akki. During the initial attack, it was stated that a few humans accidentally killed other humans hiding in the dark, subsequently leading to their own deaths. It is therefore possible to kill the akki with a suicide attack. If even the thought of killing someone is strong enough to stop people, then the humans could deceive one of their own into thinking that they’re ambushing a high-level bakenezumi at night and killing the akki that way.
There are two problems with Yakomaru’s plan: he can’t find and kill every human and the akki may be killed. Being the strategist that he his, there must be more to his plan and I am fairly certain it involves the biological weapon in Tokyo. The mini Minoshiro that Saki has with her stated that what they were looking for is a weaponized form of Anthrax that is highly contagious and difficult to contain. Nations avoid developing such weapons (or so they say) because they have the power to not only destroy cities like nuclear weapons, but cause human extinction. Alarm bells should have went off in Saki, Satoru, and Inui’s minds when they heard this and I’m flabbergasted as to why they decided to keep going. Infecting the akki with this weapon would be a death sentence to all humans and a complete victory for Yakomaru. His “pursuit” of Saki is probably all part of his plan to hasten their demise, not stop them.
Of course, this is all just speculation and maybe the weapon can be contained to one individual and Yakomaru really isn’t as smart as the series has made him out to be. Despite what happens in the final two episodes, I certainly will be sad to not be able to think and speculate about what will happen anymore.
