Daisukenojo Bito

Daisukenojo Bito, also known as Beat, is a character who appears in Kingdom Hearts 3D: Dream Drop Distance. A native of Shibuya, he was taken to Traverse Town by Joshua alongside Neku, Shiki, and his partner Rhyme.

Development
Beat, along with Neku, Joshua, Shiki, and Rhyme, is one of the first characters to appear in the Kingdom Hearts series who originated from something other than a Disney property, Final Fantasy, or Kingdom Hearts fiction, although he is from another game that is property of Square Enix, and is also designed by Tetsuya Nomura.

Kingdom Hearts 3D: Dream Drop Distance
Beat is transported to Traverse Town along with Neku, Joshua, Shiki, and Rhyme when Shibuya was consumed by darkness. Still a player in the Reaper's Games, Beat tries desperately to find Rhyme out of concern for her and to complete the Game. Falsely convinced by a mysterious figure in a black coat (who he believed to be a Reaper), Beat believes that Joshua is to blame for their current situation. Beat finally confronts Joshua and Riku in the Second District and summons a Dream Eater to attack them. Joshua tries to tell him that he has been tricked, but Beat writes it off as lies, saying that his "reverse psychiatry won't work this time." Riku quickly defeats his Spirits and Beat gives up out of frustration. Joshua attempts to comfort Beat as Riku blacks out.

Beat later appears in the Fifth District when Riku is tricked by Shiki and meets Young Xehanort face to face. Beat, finally seeing through the falsehood, tells Riku that he and Shiki had been tricked by Xehanort into believing that they could be transported back to their world if they delivered Riku to him. Confronting Xehanort directly, he tells him "I bet you aren't even a reaper." Xehanort then summons Hockomonkey and Riku pursues it into the Gardens.

After the battle, Beat and Rhyme are reunited through the efforts of Joshua, using Rhyme's dreams as a portal between the two "imaginings" of Traverse Town. Things go well for sometime until the Players receive the seemingly impossible mission of defeating Spellican, a Nightmare with the ability to summon hordes of other Nightmares and travel between the two imaginings of the town at will. With no one else to turn to, Joshua guides Sora and Riku back to Traverse Town and they once again aid the Players.

Beat and Rhyme track down the Spellican in the Fountain Plaza. Riku soon arrives and the three are distracted in a friendly conversation. All the while, the Spellican's rage is building and eventually escapes due to the group's distraction. Riku, Beat, and Rhyme pursue the Spellican through the back streets and into the Third District, where it teleports into the other imagining with no other route of escape. Joshua appears and delivers the news that Sora and the others are fighting the Spellican at that very moment. A Keyhole appears and Riku is whisked away to the next world.

Despite their efforts, the Spellican escapes to another world and the Players fail the mission. Their fate remains unknown.

Origin
Daisukenojo "Beat" Bito is a character from Square Enix's . Beat is a harsh, reckless, and rather dense youth, though he has a heart of gold. He cares very much for his little sister (and partner in the Reaper's Game) Rhyme, who constantly keeps Beat's rash attitude in check. He first shows up with Rhyme to help Neku and Shiki as players, and formed an alliance. However, over the course of the Game, Rhyme is erased, due to her taking an attack meant for Beat. Left without a partner, Beat joins the Reapers and often appears to challenge Neku and Joshua to fight during Neku's second week. He eventually becomes Neku's partner during his third Reaper's Game.
