Wow you bought your copy?? How Ai-chan filled is the extra content (if I may ask you)?
I bought it for the simple fact that I liked the series, so this is my way of showing that.
It doesn't looks like there is much additional content, but my DVD extraction softare seems to have misbehaved (meaning it did extract the extra menu's but not the extra content)
It looks like there is a picture slide-show and the theme song seperate on disc 1, and maybe something on disc 5, need to retry that one.
does it have subtitles???
No subs, not expected also as this is a Japanese release.
If you want subs, go to d-addicts.
