History Foil / TheWorldEndsWithYou

* Neku with all of his [[VitriolicBestBuds Part]][[RedOniBlueOni ners]], [[AntiVillain a]] [[MadMathematician few]] [[BigBad Reapers]], and one HotBlooded KidHero.

* Uzuki and Kariya. Both of them are AffablyEvil Reapers and have VillainousFriendship towards each other. But while Uzuki is an AlphaBitch {{Jerkass}} who is easily excitable and [[HairTriggerTemper easily angered]] and wants to do nothing but get promoted up through the ranks of the Reapers is revealed to have [[InferioritySuperiorityComplex issues]] of [[CantCatchUp her own failings as a Reaper]] and wants to move up in order to bring Kariya up through the ranks with her, not wanting to feel like she’s dragging him down to her level. Kariya on the other hand is calm and laid back, also very affable who is a lazy, good-for-nothing slacker at first, but shown to be [[BrilliantButLazy highly intelligent,]] [[AlmightyJanitor powerful,]] and surprisingly philosophical at times, the reason why he [[DecliningPromotion rejects his promotion]] is because he wanted to enjoy the little things at life as well as enjoy time with Uzuki. They also use different weapons, Uzuki uses her trusty pistol by her side in order to dish out damage and Kariya tends to rely on his bare hands in order to shoot energy blasts.

* Uzuki and Kariya. Both of them are AffablyEvil Reapers, both of them qualify as {{The Dark Chick}}s, and have VillainousFriendship towards each other. But while Uzuki is an AlphaBitch {{Jerkass}} who is easily excitable and [[HairTriggerTemper easily angered]] and wants to do nothing but get promoted up through the ranks of the Reapers is revealed to have [[InferioritySuperiorityComplex issues]] of [[CantCatchUp her own failings as a Reaper]] and wants to move up in order to bring Kariya up through the ranks with her, not wanting to feel like she’s dragging him down to her level. Kariya on the other hand is calm and laid back, also very affable who is a lazy, good-for-nothing slacker at first, but shown to be [[BrilliantButLazy highly intelligent,]] [[AlmightyJanitor powerful,]] and surprisingly philosophical at times, the reason why he [[DecliningPromotion rejects his promotion]] is because he wanted to enjoy the little things at life as well as enjoy time with Uzuki. They also use different weapons, Uzuki uses her trusty pistol by her side in order to dish out damage and Kariya tends to rely on his bare hands in order to shoot energy blasts.

* Shooter and Yammer. Both of them are {{Best Friend}}s, Tin Pin Slammer's players and fans, YoungerThanTheyLook, and wear FingerlessGloves. But whereas Shooter is HotBlooded IdiotHero who simply slams his pins with his heart and soul, Yammer is DeadpanSnarker extremely knowledgeable of Tin Pin Slammer who illegally customizes his pins to have additional abilities. As result, [[AlwaysSomeoneBetter Shooter]] [[CheatersNeverProsper is much better at Tin Pin Slammer]] which made [[GreenEyedMonster Yammer jealous of his skills]].

** Neku and Shooter. Both of them are {{The Protagonist}}/{{The Hero}} in their stories (Neku in Main Story and Shooter in Another Day), have friends that {{foil}}s to them (Neku with Shiki, Joshua, and Beat and Shooter with Yammer), and are Tin Pin Slammer's players and fans (although, for AD!Neku. Main Story Neku doesn't treat it like SeriousBusiness). But whereas Neku is a DeadpanSnarker ByronicHero who is brooding, calm and calculated, Shooter is a HotBlooded IdiotHero who is passionate, strong-willed and brave-hearted. Even Shooter treats Neku as [[TheRival a rival]] at Tin Pin Slammer (Again, Main Story Neku didn't want to involve himself with Shooter. But, AD!Neku gladly accept it). Neku and Shooter even get [[ColourCodedCharacters corresponding color designations]] in Another Day, where Neku is Blue while Shooter is Red. And that even play as a TPS team called "[[{{Sentai}} Kindred Spirits]]" where Shooter is TheHero and Neku is TheLancer. A complete ShoutOut towards [[Franchise/{{Pokemon}} Ash and Gary]].

** Neku and Beat. The former is a DeadpanSnarker who gradually learns to open up to people and fight for the sake of people besides himself, while the latter is especially devoted to his partner and sister to the point where he would join with the Reapers in the hopes of restoring her to normal. Even [[AllThereInTheManual the game manual tells you]] that they're opposites.
** Neku and [[AntiVillain Kariya]]. In gameplay, all of Kariya's attacks are supercharged versions of Neku's psychs.

* Shiki and Joshua. Despite Shiki not having any face-to-face contact with Joshua in the main game. [[MoralityChain She constantly encourages Neku to be more thoughtful and caring for others]], appealing to Neku’s better nature, whereas [[TheCorrupter Joshua tries to passively encourage Neku to give in to his hatred of others and self-defeating cynicism.]] She is also more supportive and encouraging of Neku in contrast to Joshua’s constant trolling of him.
* Beat and Rhyme. Beat seems HotBlooded and devoted to becoming the best skater ever, while Rhyme is calm, but doesn't have a dream of her own. It eventually turns out that they're the opposite of how they seem at first; Beat initially lacked motivation, while Rhyme "had a million reasons to live", in Beat's words, and she kept believing in him. Not only that, but they're also siblings.
* Beat and Konishi, in many ways. Whereas Beat is a loudmouthed IdiotHero with a penchant for [[LeeroyJenkins charging into a fray with no plans]] and being fiercely devoted and protective of the people he cares about, Konishi is a calculating ManipulativeBitch who always tries to plan two steps ahead of everyone else and will [[ChronicBackstabbingDisorder backstab just about anyone to achieve her goals.]]
* Joshua and Minamimoto. Both of them have total disregard for human life when it comes to their plans. However, [[CharacterDevelopment unlike Joshua, who learned to improve himself for the better and to expand his horizons]] (thanks to Neku's help), Minamimoto has no such revelation and remains a crazy son of a digit right to the end.
