The Darklit Planets pin set is widely considered to be the most powerful deck one can obtain in The World Ends with You. Other than via a mingle shop, the pins can only be obtained after the game has been completed, and each pin must normally be won off from certain Noise on Ultimate difficulty. WildKat will have one of the pins for sale, which is determined by the DS unit.

Each pin may be used by itself, but when all of the pins in the planet set are in the same deck, psych efficiency is tripled. When using the deck, four of the six pins are commonly used.

Combining the planet set with the Cosmic SOS thread setup is the most powerful setup one can have on Neku, save for a few alternative setups that are focused on time attacking.

Black Uranus (Piercing Pillar S)Edit

The crown jewel of the set, Black Uranus is the primary puck passer. At a devastating 300% efficiency, this pin, when combined with a 5X puck, will singlehandedly deal more damage than the rest of the planets combined. Dealing four digits of damage per hit with this pin, even on ultimate difficulty, is typical.

It is the only planet pin of the six that is also highly useful by itself. When combined with the Over the Top set along with Speed Factor, Black Uranus' reboot time will drop to 1.05s, allowing it to infinite juggle some bosses, including Panthera Cantus.

Black Jupiter (Lightning Bolt)Edit

The primary non-puck option, Black Jupiter has a beefy 150% efficiency and fires almost instantly. Its second hit per use will be canceled if slashing is too fast, so having careful stylus control is important!

Black Jupiter is the ultimate drop of Panthera Cantus, so it is usually the final planet pin that is obtained.

Black Mercury (Splash Core)Edit

The secondary puck passer and non-puck option, Black Mercury's orbs hit at a monster 195% efficiency. To avoid having all pins drained at the same time, it is important to drain the entire pin while using this, only interrupting for Uranus when the puck is returned.

Black Venus (Force Rounds)Edit

The tertiary non-puck option when Jupiter and Mercury are rebooting. Black Venus deals the least damage per hit at 75% efficiency, but has the fastest firing rate of all the planets and is easy to drain.

Black Mars (Pyrokinesis)Edit

Black Mars is used rarely, only when Jupiter, Venus, and Mercury are all rebooting due to pin mismanagement. At 105% efficiency but with a slower firing rate than Venus, it deals less overall damage than the other planets.

Black Saturn (Dark Barrier)Edit

The black sheep of the set. Black Saturn is typically never used, as the damage output from the offensive pins is so high that healing isn't required. If Neku is wearing Cosmic SOS, healing from Saturn would take Neku out of SOS, removing his attack bonuses.
