To Heart 2 (トゥハート２ Tu Hāto 2), stylized as ToHeart2, is a Japanese romance visual novel developed by Leaf and published by Aquaplus. It was first released for the PlayStation 2 on December 28, 2004 as an all-ages title, and was followed by an adult version playable on Microsoft Windows and subsequent all-ages versions for the PlayStation Portable and PlayStation 3. This deviated from the release history of the game's predecessor, To Heart, which was originally released with adult content prior to receiving versions with such content removed.
The gameplay in To Heart 2 follows a branching plot line with multiple endings, which offers pre-determined scenarios and courses of interaction based on the player's decisions. Its story centers on the male protagonist Takaki Kouno, and focuses on the appeal of the female main characters.
