Yes,I've heard of hotaru.
Here's the info for it from site Frozen Call:

Chihiro will sing the theme of a Japanese film Last Game—Saigo no Sokeisen (The Last Baseball Game Between Waseda University and Keio University; http://www.lastgame-movie.jp/)—which gives a picture of students who were killed in a battle during World War II—due out in August. This fantastic ballad, titled "Hotaru" (Firefly), has been picked up by the film's production staff from the collection of her unreleased songs. "Hotaru" is also expected to be released in August and will be sung live at the forthcoming concert this month.

also,if you go to http://www.lastgame-movie.jp/ , you can hear the preview of the song on the video.

I really like the name of the song and I also can't wait for the movie <3

^Sweet! Thanks for the info!

The snippet of the song in the trailer sounds gooooooooooooooooooooooooood! I can't wait for the single =D

Waa I want to hear the preview!! But I can't find the link to the video XD Where do I need to click?

First click on that little box that's brownish with the red circle with the arrow in it. A little popup will come up, There will be a row of Japanese text you can click, click the one right before the last option and it'll bring you to the movie trailer, which has a snippet of the song in it.

I like the cover o_o!

The b-side sounds interesting too "HIDE AND SCREAM"

OMG!
I forgot to check out Chihi's news!
I love covers and the tracklist!

HIDE AND SCREAM will be a rock song! Oh yeah =)

GRACE wants another infection, not a rock song =(

OMG!!!YAAAAAAAAAAAAAY!
LOL,Like another Sodatsu Zassou?!?!
THAT would be aswesome!

Maybe ehehe!
I am really excited for this single!
Did you saw her new pics? They are so rockish xD
I uploaded one in wiki page.

EDIT: Is it this pic?

(OMG,where did that smily appear from??)

I saw the one that was there before too.
she looks kinda weird but cool and rockish!
So I love them!
Do you have more of these?

Put her kanji name in google, and go to the images...I think you'll find.

I just saw that her site has them but only the face, not full body xD

Oh,ok.Thank you!
I really can't wait for the single!
Especially if HIDE AND SCREAM will be a rock song! <3

I just started listening to her a few hours ago! I love it all! I'm downloading LAS VEGAS now... What do you guys think is her best album?

Well...I'm not a big fan of her albums.
I love her singles way more.

Insomnia is a good album. But I really can't choose the ONE.

I like Insomnia best, with This Armor REALLY close behind it.

If you REALLY want a good album, go for Singles 2000-2003 since that'll give you the best sampling of her best songs. Recommend Cage, Watashi to WARUTSU wo, and infection
