Intimacy

Intimacy is a primary feature in NU: carnival which tells the intimate story between Eiden and each ally obtained by the player.

Mechanics
The player may give gifts, easily obtainable from Daily Quests, to any R, SR, or SSR-ranked allies, increasing their intimacy meter. Giving gifts uses up Intimacy Points, which regenerates once every ten minutes. Once the meter is full (reaches 100%), the player unlocks that room's story scene or gratitudes, and the next room with an empty meter. Completing a room will also increase bond with the allies and unlock Free Mode that allowing gifts to be given infinitely within the room.

Rooms
Each ally has five intimacy rooms. There are three types of room.


 * Gratitude
 * R and SR-ranked allies offer three or two gratitudes, respectively. Completing this type of room will give the player . Completing the last gratitude room will also give.


 * Regular scene
 * Both R and SR-ranked allies offer two regular scenes, while SSR-ranked allies offer three regular scenes. Completing this type of room will unlock the scene.


 * H-scene
 * SR and SSR-ranked allies offer one and two H-scenes, respectively. Completing this type of room will unlock the scene.

In addition to filling the previous room intimacy meter, the second and the last room with scene must be unlocked by ascending their star ranking to 2 and 3, respectively. Alternatively, a key matching their element can be used to unlock. But a Fancy Key, which can be forged from five keys of the same element in the Workshop, is needed to unlock the last room. For R-ranked allies, since the last room with scene is also the second room, rule from the second room is used.

Gift rate
Gifts can be divided into four types, Basic, Intermediate, Advanced, and Ultra-rare. The following is the rate of how much intimacy meter they can increase for each room.
