I don't think they did any more repros after the 
inital set >.<  Also other than Taro about two 
years ago I've never seen another Kamikaze 
genga/douga...The one set I own was a complete 
cut set bought from Taro many moons ago and it 
was from ep 40 something, so I would assume the 
studio was letting whole bunches of scenes and 
sketches go out at some point ^^;  I know this 
was completely unhelpful >.<

I would love to see some more douga/genga...and 
I've never seen any for Full Moon o Sagashite 
either, maybe it's just part of it being an 
Arina Tanemura show? ^_^
