Hahahahahahaha. Man, I love being wrong! That's one of the nice things about this manga, it makes me be wrong so often. Makes lots of sense, memory loss doesn't need to be due to a split personality, we were just confused (or intentionally deceived) by Leader's behavior after the memory loss (trying to run away, deceiving the referees close to him using pieces of information that have been thrown around, etc), which could have been explained by an alternate personality, but also, as it seems, by having clear instructions on what to do when he loses his memory and being incredibly intelligent. It's so fucking cool how he responds in neutral ways that make other people inadvertently reveal more information despite having no clue what they're talking about and how he uses all the clues around him to piece everything together. Fucking awesome. Love it. Nice credit page, too, you guys are amazing <3. P.S.: That guy talking about the Bee transformation was right... He must have been a raw reader!
Edit: Btw, Page 14, second panel, "expect" instead of "except".
