I can only find the audio for the 3rd edition which is slightly different. I tried looking at the kodansha us page but I can’t find anything! I’ve been searching for abt 1 hour now. Any help greatly appreciated. This is the book I have if it helps.

**EDIT:** So I emailed kodansha.us directly and they responded to me within 30 minutes, wow! From their reply, it seems that they are still working on adding audio files back on the site as their new website is still in beta. However in the meantime, they have sent me the audio files directly. If anyone reading this post is still unable to find the audio files on the kodansha us website (i.e they are still not uploaded), just drop me a DM and I’ll send them over to ya.
