There are some parts of the story that I couldn't quite understand tho, so I'm outlining the story here, if I get anything wrong please correct me because I really want to figure out the whole detailed story.
Spoiler below:
SO Lambda was Jakurai's patient, and they became best friend, but unfortunately he didn't survive. He died, and Jakurai still wanted to save him, so he started his crazy experiments. He made clones of Lambda which are called Ramuda, but Lambda became some kind of ghost (?) and killed all of them because they were all connected in some way, and I assume that the reason why he did this is that he thought he wasn't Jakurai's only one anymore (I'm not sure tho), and every Ramuda doesn't have the memory with Jakurai. And then there's a special Ramuda that Lambda decided not to kill him (I wonder why, maybe he started hating Jakurai so much that he wanted to kill Jakurai instead of Ramuda?), so Lambda told this Ramuda about the clones and Ramuda ran to Shibuya, Lambda told Ramuda to kill Jakurai.
At the same time, for some reason Jakurai sent a threatening letter to them, I don't know why Jakurai didn't want Ramuda to go to Shinjuku, I thought he wanted to apologize? Or maybe Doppo and Hifumi knew they were coming to kill Jakurai so they wanted to scare them off? But this couldn't explain why Jakurai told them not to let fling posse go to Shinjuku. Anyway they still got to Shinjuku eventually and Ramuda found Lambda there, so maybe it means that the Lambda ghost can only stay at Shinjuku or like he can't remain for long if he's at other places? And Lambda defeated Ramuda and somehow kind of controlled him or possessed him? And then they fought and killed Jakurai, Dice, and maybe even Gentaro.
Suddenly they are at some parallel universe and everyone revived. Jakurai got too caught up and accidentally made himself immortal in the experiments so he'd never die, but why did Dice revive? Anyway they fought Ramuda and Lambda. Lambda mentioned that Jakurai could only revive at their world, so does that mean they revive because the world they're at is the parallel universe? but how did they get there? did Lambda bring them there? why'd he do it, if he wanted to kill everyone then why did he bring everyone to a world that could revive everyone? So They defeated Lambda and went back to their original world (so does that prove that they got to that parallel universe was because of Lambda?), everyone revived (I wonder why), and before fling posse left, Ramuda told Jakurai something. I wonder did he remind Jakurai their memory or maybe just played a memory in his head? Like I still don't understand what he did by now.
That's all, this is like the longest comment I've ever posted, if there's actually anyone who reads all my comment then thank you very much, and I really want someone to answer my wonderings or tell me what you think about the story. Anyway, I love this story so much.
