There are a number of To Heart dolls and plushys available. To the left you can see the UFO catcher dolls. The bottom image shows a small figurine set for the TV series. There are also some figurines for the Piece of Heart story (which deals mostly with Serio).

I have more images, but at the moment I'm too lazy to post them ^^; You'll have to look out for them in the future ne ^_- I promise to fix this section up too. It's quite hideous
