Oh Berryz Koubou.. I discovered them around the same time I started getting into Morning Musume and although their songs aren't my favourite in Hello!Project and aren't even my particularly favourite group, it does contain my absolute favourite member Risako whom I just fell in love with at first sight. It's interesting as a group how they evolved from such little girls into grown women although they have still retained their silly nature. The group debuted in 2004 and are now on their upcoming 30th single. They were formed from Hello!Project kids, which another group of girls broke apart and became their fellow group C-ute which has had a more mature sound. These are my top 5 singles from them in backwards order of release.

In this world, no matter where you are

[2009.03.11] Dakishimete Dakishimete (Hold Me, Hold Me)
The sweet future or a passionate hope
Those swelling thoughts grow fainter
Somehow, don't let them disappear
