Gameplay
The player assumes the role of Takaaki Kouno, the main protagonist of To Heart 2, however, this character cannot participate in battles directly. Instead, the player controls what skills and attacks the girls Takaaki encounters use. In the beginning, the player will start off with two party members, Konomi Yuzuhara and Tamaki Kousaka, with these two characters, more girls can be unlocked to fight in the party. In order to unlock more party members, the player must defeat certain characters in the To Heart 2 series, and then they will join the player's side.

The party will often encounter enemies, which offer little experience compared to boss battles. In the PC version, a maximum of four people can be in the party, whilst in the PSP version, it is five. Each character has a different occupation, when the character reaches certain levels, they can advance to a higher class. The career changes for a fighter at level 15 are Paladin and Dark Knight, and at level 30, the career changes are Valkyrie, Samurai, and Dark Lord. The career changes for a magic user at level 15 are Sorceress, Enchantress, and Priest, and at level 30, the career changes are Witch, Magical Princess, Sage, and Bishop. The career changes for a scout at level 15 are Archer and Assassin, and at level 30, the career changes are Sniper, Treasure Hunter, and Kunoichi. Lastly, the career changes for a maid at level 15 are Bard and Dance, and at level 30, the career changes are Diva, High School Girl, Idol Master. Each class has a different costume.

All of the characters have their own skills and special attacks, they can be learnt by earning skill points which are obtained when the party levels up. There are six different types of skills:
 * Passive Skills - Effects of the skill apply to the entire party which is always activated.
 * Skill-based Skills - Skills that activate immediately when in combat.
 * Magic-based Skills - If in combat, there is a cast time for magic users to activate their spells, however, if attacked by an enemy in the process of doing so, the skill will be cancelled.
 * Unique Skills - Added in the PSP version. It is the skill of a specific character, which can be strengthened.
 * Party Skills - Added in the PSP version. A skill activated by party members.
 * Cooperation Skills - Added in the PSP version. The skill can only be activated if the party meets the conditions/requirements (occupation, equipment).

Items can be obtained in the dungeons, or bought from a shop. There are weapons, armor, and recovery items. Recovery items are necessary to fill back up a party member's health bar, or their magic power. If their health reaches 0, that character can no longer participate in the battle, unless they are revived.
