From UPYOLIC SOFT:
Japanese traditional card game called 'Hanahuda' that means 'Flower Card Game', with pure anime girls, only for Mac OS X, the light free edition of 'Koikoi Komachi X INTL. (International)'. This is not a strip game, everyone can enjoy Hanahuda. Reina will play 'Hanahuda' with you, she speaks very well with pretty voice.
