I love to study the real Japanese that people are speaking. I think Peter and everybody are great fun. I have a few suggestions...
I like it best when Peter is in the audios.
When you write the transcript in only furigana, you don't separate the words. This makes it hard to read. Sometimes I don't know where one word begins, and the other ends.
Also, some of the voice actors sound really creepy when they are doing their impressions of old ladies, children, old men, and etc. I think it is not authentic. It is like there are trying to overact, and it comes out sounding very hen and kowai.
