I found out that Re:Zero has a public web novel version that is available for free due to this question
I did some searching and found the English version on Novel Update. However, I only see it begin from vol. 3 (without vol. 1 or vol. 2).
I would like to know where I can find Re:Zero Kara Hajimeru Isekai Seikatsu (web novel) in English, from the beginning (vol 1) until now.
