Thanks for this addition. Very interesting to read.
It's awful that the death scene was based on real events... it was crushing enough to me when I first read it as just a part of a fictional story. I hope the author and his passed friends have found peace.
Thank you for the afterword, it made the story shine even more. I think it was a very important piece to make Bakuon Rettou complete, it made me recall whole story in different light once again.
