Good news here as this is one of our Priority 2's! We featured this album last summer, so you can read my thoughts of the musical contents there.
This reissue is coming out in Japan via mini-LP, so it is likely to be expensive. The label is Production Dessinee, which I'm not familiar with, but they apparently have quite a few other releases - all outside our scope (or I think that's the case anyway).
Thanks to Laser Ken for the tip!
