Thanks to Ayu's diary entry from Misa-chan, we now know who worked on MOON!
MOON
music: Yasuhiko Hoshino (composed almost all of ASFXX, the album)
arrangement: Yuta Nakano
It's rather amazing, isn't it? After more than 10 years, they're reunited again!
From Luna62:
ASFXX
Prologue, A Song for XX, For My Dear..., FRIEND, Hana, poker face, Present, YOU
LOVEppears
And Then, kanariya
Duty
End of the World, girlish
He recently did Kie Kitano's SAKURA SAKU. (Arranged by BOUNCEBACK, who composed/arranged most of what was on Memorial address.)

Sounds like an Ayu song, haha.
He also worked on MAX's Give me a Shake.
