I'm sure it'll be on e-Lineup at some point. The last of these Nama Tamago Shows is on the 29th, so maybe sometime after that? I'm just guessing here lol.
(I mean, shit, I'll probably end up buying the thing if it's possible for me to do so.)
I got the first Kenshuusei single at the Berryz concert today! They had their other single and DVDs. So hopefully it'll be available at all H!P events they take part of.
