Something I've been thinking of is why the hell Koujaku carries that big ass sword with him everywhere.
He wants to forget his abusive past and everything that haunts him in nightmares, he says himself that he wanted to forget his revenge once he was in the island, so why would he carry a sword that he doesn't want to use? It's not like he needs it to fight, he knows how to, he does it frequently and got training as a kid, he wouldn't have a problem with the bunch of tryhards that try to defeat him in the island. Makes no sense to carry a weapon that would only remind him of what he was forced to do.
So anyway my main point is that I think him not carrying it would add a lot more to his character. They basically made him carry it because design stuff I'm guessing, convenience or whatever. Besides the fact that not carrying it would make more sense for the person he wants to be in the island, I think it would add to the mistery they build around him.
When things get dangerous, suddenly he appears with a sword, since when does he have it? How does he know how to use it? When and how did he learn? You know what I mean. The whole point of the conflict between him and Aoba is that Aoba starts to discover a bunch of things that relate Koujaku to the yakuza, you know, dangerous people. Which is funny because Vitrip, but anyway, you could still explain why Aoba trusts them and starts doubting Koujaku because Virus and Trip say it out loud and say that they don't do the dangerous stuff. Even if they're lying, they're lying very well and Aoba believes them, he doesn't have any reason not to, specially since he knew them before they joined, supposedly.
But Koujaku, that avoids everything he can about his past, has hidden his tattoos, he started acting weird, etc, suddenly appearing with a sword that he can use perfectly and having that murderous and tenacious aura he's suposed to have would make Aoba's doubting feelings more intense for him and for the spectator. I don't know, maybe he got his sword hidden in his house when he gave up his revenge and takes it when they're about to go to Platinum Jail, maybe he could grab a random sword from someone they fight, anything that is just not from the start.
Also him having that murderous aura when he fights I think could be a really nice resource to use too, he doesn't look like that until he fights Ryuhou and is mad as fuck (or well, the glitter incident, but i mean exclusively when using his sword).
When he fights dummies in the island he's like always, but when in PJ he sees signs of Ryuhou being around it clicks and starts with that relentless, no mercy fighting style, that even Aoba is like ??? π¨. He's a killing machine. In the end, he was born a slave, and he'll always be unless Aoba can scrap him correctly. Him being Aoba's slave in his bad ending is just perfect, the only reason he's still alive is because Aoba wanted him.
(in conclusion he likes aoba using him when they have sex)
