All MP3s are back up again. Enjoy ^^

Kanashii Tokiha Itsumo
This song was played when Ginta was asking Arimi what she wanted for Christmas (her answer was "Kiss Kiss Kiss". Ginta's reaction was really cute ^_^) The vocal verion of this song was sung by Kanemaru Jun'ichi, Ginta's VA. I have the vocal version and the BGM version for you to download. Both are really nice.

Taiyo wo Sagashite
This song was played when Ginta and Arimi are hanging out at the Toryou school carnival, and when Miki schemes to get the couple back together at the Wonder Dog amusement park. I really really love this song. ^_^ It's sung by Arimi's VA, Hisakawa Aya, and like the above song has a vocal and BGM version.

This song is a duet between Ginta and Arimi, it's one of my favourite Marmalade boy songs ^_^
