For those who have just learned about Hakaiou, I recommend reading the manga version as well as Evoluder Guy if you don’t know where to start. You can get through a lot more content in a lot less time that way, and the novel’s available too if you decide you’re invested enough.

This is a great thing to have, especially since SRW 30 just announced including Hakaiou.
