Where Allen wears a frilly cravat. <3 And bluffs and uses underhanded methods to win court battles.
Kanda is a little like Simon Blackquill with all the sword metaphors.
Link is Allen’s companion in investigations, and Allen always insists that “it’s just a ladder”, while Link comments that Allen needs to appreciate a little more specificity, or else he won’t get anywhere in life, while Kanda really couldn’t care less.
Allen’s first case is the murder (???) of his mentor, Cross Marian. He has to defend Neah Walker, while the real murderer is Apocryphos—except right before the Earl delivers the “NOT GUILTY” verdict, Cross slams the doors open with his foot, and yells: "Who told you bastards you could write me off for dead? *evil glint*"
Kanda is later accused for the murder of Alma Karma. Allen offers to defend him, after much, much arguing and stubbornness. Even then, Kanda realizes that he might have done it after all, and pleads “guilty”. Still, Allen believes in him, even if Kanda doesn’t believe in himself. Turns out Alma’s death was not because of Kanda strangling him (since Alma—y’know, killing spree), but because of an artificial hallucinogen/poison injected into to him by Lvellie, who stole it from the Science Department. (Motive being that Alma knew something that could destroy the 2nd Prosecutors’ project.)
Kanda leaves a suicide note: “Prosecutor Kanda Yuu chooses death”, and Allen is fucking devastated and the anger torments him for half a year, before Kanda returns just when Allen’s in a pinch. He says to Allen, that his purpose as a prosecutor will no longer be out of revenge, but the find the truth, and become, like Allen—a destroyer who saves. Allen… Is really moved. But still really angry at him for disappearing on him. This time, the accused is the Earl (yes, the Judge), who is accused of killing Mana Walker, but no prosecutor is willing to file charges, because of the Earl’s connections and manipulation in the background. No one, but Kanda. Until the Earl kidnaps Lenalee, and forces Allen to be his defense attorney. Well, much stalling later, Link and the police department, and Komui with a giant robot (with feelings), crash into the court house wall, with the Earl captured, and Lenalee in safe hands.
The anger dissipates eventually, and they pitter patter around each other awkwardly in stupid love. Everyone gets fed up with their courtroom UST. Zhu, the new judge, despite his usually calm manner, once slammed the gavel so hard, it flew and got stuck on the ceiling, and he shouted: "The defense and prosecution will CEASE their thinly-veiled courtroom eye-sex, and save their homoerotica for AFTER the trial! God! Kids these days."
It takes a promotion (for Kanda) for the idiots to finally admit they’re mad for each other. Right before the plane leaves for Japan, Allen tackles him out of the line. They bicker and bicker (“You fucking idiot! Now I have to line up all over again!” “As if! You’re not going anywhere, I need you!” “??!” “U-Uh… Yeah, got a problem with what I said? *bluuuush*” “Will you two lovebirds get a room?!”), and Kanda… He goes to Japan anyway. He tells Allen to wait for him.
Allen sends him nasty (mirthless and childish, really) snail mail written by a 3-foot feather ink pen (the writing is illegible) for the next few months (even though there’s email, and they do video calls twice a week) until Kanda comes back screaming at him to stop (“Why the fuck are you still writing?! I told you yesterday I was coming back! And who the fuck is Kato?!”).
And then they spend the rest of their life having high-tension court battles together, on the constant quest for the truth. :q
