The LN has not been translated, only the WN, which is very different and has shit story
@pachogamez Strongly disagree. The story in the WN is fun and it's intention is to make fun of itself. I have not read the LN, but if it's really that different then it can only be worse, as the WN was really, really good in it's own way. It's just not in a standart way.
