Sync Rate is one of the characters stats. It is shown in-game in Neku's partner side of the screen, but it is really a shared stat (like their Max HP) between the two characters in a pact. It affects, and is affected by, both characters.

What Sync Rate Affects[]

Sync Rate affects how long the Light Puck can last before it disappears when no one passes the Puck, and, more importantly, how long you can hold the puck before your multiplier starts draining away. With a 0% sync rate, you must pass the puck virtually instantaneously just to get past a X2 multiplier, but with an increased Sync Rate, you have much more time to pass the puck, and when you do, the multiplier increase is almost always better.

In the Remix versions, Sync Rate is what decides whether the player can invoke a Fusion, and what level the Fusion is when invoked. 100% permits basic Fusions, 200% level 2, and 300% level 3 Fusions. Maximum Sync Rate in these games is no longer capped at 100% during battle, but instead the maximum value is equal to 100% times the number of (S) Fusion Boost stickers the have been obtained for the current partner. Sync is still capped at 100% outside of battle though.

What Affects Sync Rate[]

Sync Rate drops when your characters get damaged in battle. Wearing Threads of a popular brand in that area of Shibuya will alleviate the effect. Sync Rate will also drop if Neku runs away from battles often; If Neku runs away with a 3-bar battery gauge, no percentage of Sync is lost. This is basically a warning. If Neku runs away with a 2-bar gauge, Neku's partner will get upset and their Sync Rate will drop by 20%. If Neku then runs away with a 1-bar, his partner will be furious (except for Joshua, who gives Neku the silent treatment and makes Neku mad at him), then he and partner's Sync Rate will drop by 40%! The Phone battery gauge increases if Neku can win each battle/Reduction.

It is also affected by Food in many ways:

  • Always boosted temporarily during digestion of any food
  • Boosted after digestion of certain foods. This secondary Sync Rate gain is not affected by character's personal likes and dislikes.
  • May be affected by the like/dislike of the food by each character:
    • Loves it: 2x
    • Likes it: 1.5x
    • Okay with it: 1x
    • Dislikes it: 0.75x
    • Hates it: 0.5x

The foods that result in secondary increase of the Sync Rate are the following:

In both Remix versions, sync rate increases in battle with each successful partner attack by a small amount, and increases more whenever a Cross Combo is performed by either character. Certain threads can boost this amount, and other threads can provide a fixed percentage boost to sync at the start of battle. After a battle, the ending Sync Rate and the players' performance in battle act to determine how much sync the players keep between battles, which is capped at 100%
