It is a good start to just fall from the sky, and then accidentally kill a monster.
End of school arc
I don't really remember if Fritz was reveled as Sylphy from the beginning. Was it the reader that didn't know or just Rudeus that didn't know. It was quite a while when I read a web novel.
The whole pretext was out of order compared to the LN. I'm okay with it because the story is in a different format and may change with the retelling.
Originally Rudy meets Fitz, who you totally believe is Sylphie in about 30s but isn't confirmed in quite a while. I felt like I was arguing with the author to tell me it was her for quite some time.
