So I just wanna make this clear, I've only seen the anime and know about the eight mangas, but what happened? I tried a couple years ago to find out what happened and I can't find the web series anywhere. I ended up going to Tumblr and found some info, but I'm not sure how accurate it is. I just wanted some answers on the plot in the web series, I don't mind spoilers but I'll put a warning.
*POTENTIAL SPOILER WARNING IN COMMENTS*
All I think I know is that Jyugo was an experiment, I think his mom was killed, his friends became his friends because of the man with a scar made them(?), and Jyugo ended up becoming emotionless and leaving behind his friends after they apologized.
Please correct me if I'm wrong! This was all based on Tumblr posts I read so if you know more about what happened in the web series please tell me in the comments 🙏
