So I decided to do a quick character introduction guide to the main characters of each series to be involved. This is the TWEWY edition of said intros. Timeline-wise BKH begins at the epilogue of TWEWY, after the combined events of both DDD and TWEWY. How that fits together? That will be revealed in the story. Enjoy.
Neku Sakuraba: The main protagonist from 'The World Ends With You'. He is a skinny 15 year old with orange spiky hair, and a love for Music and Graffiti Art. He is almost always seen wearing his very limited edition headphones, with an MP3 player on the lanyard around his neck. He dresses, much to his fashionista friend's chagrin, in his favourite Dharma (a baggy collared singlet), white cargo shorts, and sneakers. Neku is a skilled practitioner of Psychomancy, abilities akin to magic, and due to his very potent and variable imagination is able to use most of the known Psychs available to Players. He can even use some of the more powerful and reaper restricted ones.
Previously an extremely anti-social teenager after his friend died, the reclusive Neku became involved in the battle for Shibuya when he was killed by Joshua. Chosen to be the Composer's Proxy in the Reaper's Game, while having no memories being his entry price during the first week. At first his unwillingness to open up annoyed all of his partners throughout the game. However after 3 weeks of the Reaper's Game he managed to emerge victorious over all three Game Masters, The Conductor and then proved himself to the Composer. At the end of this journey Neku had changed, was able to open up to others and gained new friends. Trust is a big thing for Neku, and though he still comes off a bit arrogant upon first meeting him, he no longer willingly shuts people out of his life.
Shiki Misaki: A protagonist of 'TWEWY'. She is a 15 year old girl with short brown hair, glasses, and a love for all things fashion and sewing. Day to day she wears a comfortable green cardigan over a black tee, and a floral knee length beige skirt over black tights. She constantly carries around 'Mr. Mew', a cat doll she made herself, which also becomes her weapon. Shiki primarily uses 'Groove Pawn' in combat, a psych that lets her bring Mr. Mew to life as her ally. While she cannot directly control it thought for thought, Mr. Mew holds the protection of Shiki, then her partner highest in its priorities. Shiki can also use a few rare Psychomancy abilities that allow her to make Mr. Mew more dangerous by temporarily replicating him, enlarging him, and/or granting him new methods of attack.
Shiki is a kind and helpful person, and will often be the positive driving force in her friendships. However she can have a low opinion of herself despite the happy attitude, and Shiki can often feel useless and jealous when it comes to her idols. Shiki was Neku's partner during his first week of the Reaper's Game. She became a Player of the Game when she died from an unknown accident, causing her appearance to change and match that of her friend Eri, due to Shiki's own appearance being her entry price. Over the course of the week, Shiki was able to become Neku's first true friend. Since her return to life, she thought Neku wouldn't like her in her real appearance, but was happily mistaken.
Yoshiya 'Joshua' Kiryu: A protagonist (and the secret antagonist) of 'TWEWY'. Joshua is the Composer, Shibuya's spiritual overlord. His true form as the Composer appears as a glowing white angelic humanoid and vaguely resembles his human form, though older. When repressing his power to appear human, Joshua regresses back to his 15 year old appearance, with mousey brown hair, adorned in a light grey shirt and black trousers. When within Shibuya, Joshua is able to utilise the full abilities of the Composer, able to shift between dimensions, have perfect control when using potent psychic abilities, and is completely capable of destroying Shibuya should he wish too. In his human form he uses teleportation and telekinetic Psychomancy and is able to trigger blasts of heavenly light. His so far unseen Noise form, remains a mystery.
Joshua is an intelligent individual, but it is often overshadowed by his arrogance and smarmy nature. Mysterious and normally independent of others, in reality he is quite lonely due to his position in the spiritual Hierarchy. Other than his relationship with Sanae Hanekoma, Neku is the only friend Joshua had been able to make in a long time. It is from befriending each other that both Joshua and Neku were able to change each others perspective on life and humanity. This in turn led to Joshua's decision to not erase Shibuya, trusting that if his friend's outlook could change for the better, then maybe so could the worlds.
Daisukenojo 'Beat' Bito: A protagonist of 'TWEWY'. Beat is a 15 year old teen with blonde hair (natural). He dresses day to day much like the Skateboarder he is, a white singlet, yellow cargo shorts, red sneakers, a selection of chains, and his trademark Skull Beanie. He is also an impressively skilled Skateboarder. In combat Beat is a physical battler with his 'Respect' Psych, using his Skateboard and fists as his weapon of choice to slash and smash his opponents while dodging and dashing around them.
Beat tries to act tough and punk, but he really has a heart of gold and cares for his sister Rhyme deeply. He ended up in the Reaper's Game when he attempted to save his sister from being run over, but both of them ended up being struck by the car and killed. His entry price was Rhyme's memories of him. Beat can be very loud, impulsive and a bit slow on the uptake sometimes, especially when he can come to conclusions without any good reason, nor figure out complicated insults immediately. During the Reaper's Game he became a Harrier Reaper in the effort to keep his sister 'alive' as a Noise, but eventually he returned to the Player's side as Neku's final Game partner. Despite his flaws, Beat always means well and will do good by his friends any day.
Raimu 'Rhyme' Bito: A Protagonist of 'TWEWY'. Rhyme is the 13 year old younger sister of Beat, also having naturally blonde hair and love for skull thematics. Day to day she wears a peach long sleeved skull tee, white shorts, and black sneakers. She also wears her own black skull beanie. Rhyme's style of combat revolves around her Psych 'Vox Pops', a close/long ranged ability similar to the Time Bomb and Pressure Mine Psychs, however the miniature explosions can have variable effects, allowing for her to play a healer role as well. Due to the Reaper's Games she was involved in, it is known that Rhyme's Noise form is a Flying Squirrel Noise, 'Petaurista Cantus'.
Rhyme is a cheery, optimistic girl with a calm demeanor. Young and pure of heart, Rhyme is loved by all good souls who meet her and her kind smile. She also cares for her big brother very much. Rhyme entered the Reaper's Game when she and her brother were run over, where her entry fee was actually her dreams. She and Beat teamed with Neku & Shiki until [REDACTED], which resulted in her subsequent erasure. Hanekoma saved her by binding her remaining soul to a pin, creating a noise summoning psych that would be which would become both Beat and Neku's salvation. She was revived back to human after Neku 'won' his challenge, but as she 'lost' the Game, the entry fee of her dreams couldn't be returned. In reality, [REDACTED].
Sanae Hanekoma: An ally of the protagonists (and the Composer) of 'TWEWY'. Sanae is a fallen angel, with a human appearance of a man in his late 20's, wearing a white shirt, grey waistcoat, and black trousers with sandals. He also wears a pair of sunglasses. As a cast out angel, Sanae has access to separately summon his Noise Form for combat, an extremely powerful and rare two part Noise called 'Panthera Cantus'.
Sanae is a helpful and fair sort, playing the wise man role to his allies and giving Sage advice to Neku and his friends. He's laid back, a tad enigmatic, and enjoys confusing folks before helping clear up their doubts. As the Producer, Sanae acts as tutor, guardian and guide for the Reaper's Game players, maintaining fair play and the rules in the name of the Composer and Player. He was expelled from the Angelic plane for aiding in Sho Minamimoto's use of Taboo Noise.
