From Trigger Magazine #006:

The first volume for KILL la KILL is now available for preorder in Japan. The bonus features seems pretty nice too! I hope I'll have money to spare before the Blu-ray is released.

『キルラキル』Blu-ray&DVD第1巻の予約も始まりました。限定版の特典もかなり豪華ですのでお見逃しなく！僕も最近無駄遣いが激しく、発売日までに貯金できるかが心配です・・・

For International Version Only:

The long waited Little Witch Academia Blu-ray is finally available for shipping with the the special booklet! The special booklet provides translation for all text material presented in the fanbook! And, yes it is only included in the orders made oversea!
