Why did Kaneki Join Aogiri Tree?

When the  first episode of Tokyo Ghoul √A aired, Kaneki went with Aogiri (we don’t know why yet). However he did the exact opposite in the manga. Instead he tried to create a group to fight Aogiri. The second season of Tokyo Ghoul is different from the original manga in lot of ways, but what makes it admirable is the fact that producers compressed over 100 chapters in just 12 episodes. To understand why Kaneki joined Aogiri, we first need to understand why Tokyo Ghoul anime deviated from the manga. 

Kaneki, both in the anime and manga was looking for just one thing. The strength to protect his loved ones, nothing more, nothing less.  In the manga we found this out using hardcore character development chapter after chapter. Whereas, in the anime it was explicitly stated as why he joined Aogiri. The real problem with the anime was not plot, but rather the character development.

As stated above the producers did a wonderful job at compressing over 100 chapters into a single season. There are plenty of differences in the anime and manga, but they always ended up with the same conclusion. Despite that, the anime emphasized on things like Rize’s appearance and development who was the catalyst in Kaneki’s identity and power. The manga however was ridiculously slow with developments on every front including CCG.

Now let’s get to the real question-

Why did Kaneki Join Aogiri Tree?

When Kaneki first came to Aogiri tree, he was going through an identity crisis. He didn’t know what he was, a human or a ghoul? He wanted a place a place to belong, the only person close to him was his friend Hide. Despite everything, Anteiku welcomed Kaneki with open hands and gave him a place to belong. The air around his identity was cleared when Yoshimura-san told him- ‘From what I see, you are the only one who can have a place in both the ghoul’s world and human world.That makes you unique.”

But reality struck him hard after he was tortured by Jason resulting in an identity crisis, forcing him to leave Anteiku. Kaneki left Anteiku for two reasons.

  1. To become stronger, so that he can protect his loved ones.
  2. To get closer to the leader of Aogiri tree.

We already analysed the first reason, hence let’s jump to the second one. The main reason Kaneki joined Aogiri tree is because he wanted to keep an eye on Aogiri’s activities and if it ever was a threat to Anteiku he’d destroy it. Also, by getting closer to their leader, he’d have a better look at the leader who for better or worse has some evil plans. Kaneki is similar to Itachi from Naruto, where Itachi joined the Akatsuki just to monitor and keep an eye on them to protect his village.


In conclusion, it never really mattered at all if Kaneki joined Aogiri in the anime or formed his own group. Because in the end his ultimate goal was to protect Anteiku. But from a marketing perspective this was a shady move from the producers as it meant otakus would be baited to watch the second season.

What do you guys think about Kaneki join Aogiri, was it justified or was it just another spin-off from the original manga? Do let me know about it via the comments section.
