A special unaired episode of Little Busters! sent to those who bought all 9 BD/DVD volumes of the anime. This episode includes the story about "Mask the Saito".
Trailer in this MAL thread:
Not sure I will bother, not sure I can bother my friend in Japan with the 800 yen postal money order monkey business...
And at this moment I still can't order Little Busters! 8 & 9 from amazon and CDJapan is out of the LE of volume 8. Would look silly to have an RE in my collection and I don't know if the RE has the all volume bonus anyways so maybe I will just skip them... Refrain is already happening (support mission accomplished) and the bonuses aren't really that much to write home about, nice booklets I guess. Sour grapes? Yes.
Maybe I will just order the PS Vita port of the VN instead...
