Blue Reflection: Second Light

The player can have Ao walk around the school and talk with the other girls to take on side quests. Scenes occur during school, some of which involve questions from the other girls in the group, which affect their relationship to Ao depending on the player's answers. In a series of dates and bonding episodes, the player is rewarded with additional support benefits during battles. Using items obtained from heartscapes, Ao can craft new items that provide benefits and can build new attractions on the school grounds that increase character stats and serve as new locations for dates. Similar to the first title, the player can also interact with characters by messaging them through an in-game mobile app for listening to crafting requests and to ask on a date.

When exploring a heartscape, battle is initiated when a player hits an enemy from behind or an enemy hits the player head on. Operating on a turn based system, the characters cast spells by spending their own individual "ether" meters which build up over real time during combat. Spending ether points increases a character's Gears level for that battle, which increases the maximum amount of ether available to a character and the speed at which characters gain ether, in addition to granting the characters more powerful spells.

Ao Hoshizaki, a girl who regards herself as "normal," was on her way to summer classes when she suddenly vanished and awoke at an isolated high school surrounded by water, with no other people and no understanding of her situation. Ao meets three other girls who had been there for longer than her: Kokoro Utsubo, Rena Miyauchi, and Yuki Kinjou. All four girls had a ring appear on their finger when they arrived, and Ao is the only girl who was able to even vaguely retain her memories of the real world. The girls receive text messages from a person known as "ReSource" warning them to stay away from the entrance to a mysterious world called the Faraway. The girls enter and are attacked by a Demon, and ReSource instructs Ao, Kokoro, and Rena to use their rings and emotions to create weapons and become Reflectors.

Slowly, Ao and the other girls begin to recall their memories as they venture into parallel dimensions, dubbed heartscapes.

Blue Reflection: Second Light received generally positive reception. Electronic Gaming Monthly noted that the game's difficulty was low, but that it suited the game. Digitally Downloaded found and praised yuri elements in the dialogue between the girls.
