/yndd/ - Yume Nikki - Dream Diary

Something interesting about Yume Nikki: Dream Diary is that the music is all done by Diana June except for the main theme which is composed by "AQUILA".
Why do they go out of their way to emphasize that this person made the theme if they are so unknown and seem to have no other music out there? I looked up bands or artists called AQUILA and found one band that seemed to have nothing to do with it.
In the credits, after Kikiyama is credited, Aquila comes on the page after and is at the same space where Kikiyama's credit was before.
This also happens in the trailer of the game, after "full co-operation with Kikiyama" comes "main theme: AQUILA", or it's on the same page.

It's also put in the news release and on the steam page. It seems really odd that someone would be advertised like that like it's a big deal, but have no music available.
Something I did notice however was that when searching for it in Japanese, AQUILA sounds a lot like "Akira".
An officially licensed story to Yume Nikki was released January 7 this year. Around the same time the game came out for free on Steam. The author goes by the name "Akira" and nothing else.
AQUILA? AKIRA? Pretty similar.
