Leveling divas
Each diva has a quantity known as the diva level (歌姫Lv?) which can increase as you play the game [1]. Levelling up a diva can increase their six attributes; Soul, Voice, Charm, Life, Support and Fold Wave as well as unlock SNS chats that reward song crystals [2].
Song Proficiency
A given diva and a given song will have a quantity known as a song proficiency level (楽曲熟練度?) which ranges from 0 to 5 (MAX). Clearing live shows increases a divas song proficiency level [3], and does so by rewarding each diva in the unit with song proficiency points.
Proficiency Points
How many points the divas receive depends on the difficulty selected for the live show, the score, and sometimes an event [note 1][note 2]. A live show will reward base proficiency points depending on the difficulty:
| Difficulty | Base Proficiency |
|---|---|
| Easy | 70 |
| Normal | 90 |
| Hard | 110 |
| Very Hard | 120 |
| Extreme | 180 |
The score is then divided by 10,000 and rounded to the nearest integer, this becomes the percentage the base score increases by e.g. a score of 75,000 on Very Hard yields 210 points. The center diva also receives 50% more points than the other two divas in the unit.
Proficiency Levels
| Level | Points needed to upgrade |
|---|---|
| 0 | 150 |
| 1 | 500 |
| 2 | 2500 |
| 3 | 6000 |
| 4 | 13000 |
| 5 | 25000 |
| 6 | 40000 |
Upper song level limiters
Once a diva's proficiency to a song has reached level 4, they will be barred from gaining any more song experience from that particular song unless certain requirements have been met. This will typically involve a level a counterpart diva's song proficiency to at least level 3 with the counterpart song requirement, but some songs have different requirements as an exception. If the counterpart diva's proficiency level for the song isn't at least 3, the proficiency points bar for level 4 will show a lock. For each song page listed on this site, the counterpart song and counterpart divas are provided.
Experience
Every time a song proficiency level increases, the diva is rewarded with experience (経験値?). Experience increases in units of 10 and unlike song proficiency, it is unique to the diva.
| Proficiency Change | Experience Rewarded |
|---|---|
| 0 to 1 | 10 |
| 1 to 2 | 20 |
| 2 to 3 | 30 |
| 3 to 4 | 50 |
| 4 to 5 | 100 |
Enough experience increases the diva level, resetting the value to 0. The experience needed to level up depends on the current diva level:
| Diva Level | Experience Needed |
|---|---|
| 1 to ? | ? |
| ? to 13 | 70 |
| 14 to 23 | 100 |
| 24 to 28 | 150 |
| 29 or more | 200 |

Affection
After reaching player rank 8, players will have the option to interact with the diva on the home screen to increase their affinity towards the player. As the affection level increase, divas will gain bonuses, unique interactions, and even give character titles to reward the player's dedication.
Filling The Affection Gauge
There are 2 primary methods to increase a diva's affection:
Home Screen Interaction
Players can increase a diva's affection by placing their finger over the home screen diva and holding it down until the diva reacts to the long press. The hand icon will display how many times a player can fill the affection gauge. The amount of presses will recover at a rate of 2 hours per press and players can store up to 5 presses. Each press will fill the affection gauge by 30 points for each press.
Gifting
Once per day, players can give a gift to their home screen dive to greatly increase their affection. The home screen diva will also give the player hints on what kind of gift they desire based on 3 categories of gifts: ornaments, food, and recreation. Choosing the right gift will bestow a 50% bonus. Every diva also has a favorite gift that will always grant a 50% bonus regardless of what category the gift it is. It is possible for both the correct category and the favorite item bonuses to stack, so players should always try to hand out the correct gift to accelerate the affection level progression.
Currently, the available gifts to hand out to divas are given in the table below.

Footnotes
- ↑ e.g. from the Christmas Hesitation event until 2018/1/3 23:59, there was a "Strengthening Campaign" (育成強化キャンペーン?) that awarded a extra points (equal to the base points for the selected difficulty) after each live show is cleared. The center divas did not receive 50% more of this bonus as these bonuses occurred after the normal points calculation but prior to gaining experience and levelling up.
- ↑ Divas also get a boost if the game is played on their birthday
