It finally halppened, i had been looking forward to this reveal for a while. Thanks so much Team Duwang!!!
The first time I read this manga I couldn't tell if Baku was telling the truth or just messing with Yukiide (turned out to be both). The second time was after I spoiled myself about Hal and I was like "oh my god, that is some good foreshadowing."
I just love the use of Baku's story as foreshadowing. First off, Baku likes to trick his opponents, so it was hard to tell if he was being truthful. Second, the story implies that "Haru" died (or at least thats how I interpreted it, since he was involved in one of Baku's gambles which usually has life-or-death stakes, and also with the line that he never returned). Third, without spoilers, it would be hard to conclude that the name of Baku's friend was Hal and not Haru (at least thats what I think).
Ever since Souichi's memory loss was revealed I had this theory that the incident Hal got into because of Baku was what caused Hal to have memory problems. But if Baku and Hal's first meeting was really at the bookstore then Hal had memory problems beforehand. Though I still theorize that the result of the gamble that Hal involved himself in led to his memories being wiped again (at least his memories of Baku). Hal losing his memories would be what Baku meant by "killing" him. Theres also the fact to take into that Yukiide completed Baku's story for him because it was taking to long, so Yukiide's conclusion may not be what actually happened (theres also the fact that Baku did not correct Yukiide at all, which could be taken as Baku confirming the validity of Yukiide's interpretation, or Baku just didn't want to talk about it anymore.

I loved how that line was brought up in Kaji's dream too. It had been on my mind. I have believed that the person Baku "sacrificed" and Hal are the same person. If Yukiide's conclusion to the story is true, Hal participated in one of Baku's gambles in place of Baku. But everyone else could of interpreted that Baku forced Hal to take his place, therefore sacrificing him. Though my theory might be wrong because if Baku is asleep (in Yukiide's continuation of the story), how could Baku of eventually won the gamble?
Also responding to your most recent comment, Baku met Hal in 1998 and the surpassing the leader game was in 2001, so there was a three year gap. I think Hal was not the Kakerou leader and that Eba was still alive in 1998. I do wonder if theres anything in the book now that Eba is supposedly dead. I also think Eba was the one who bought the bookstore. I do wonder if Eba is still alive or if hes faking his death and in hiding somewhere? if thats possible (he seemed pretty old). Also like that you brought up Baku's previous friendship with Hal and him losing surpassing the leader being connected, I think so too. Where's the fun in beating your friend in an important gamble if the friend does not remember you at all?
