What are the chances there are no side effects from eating more than one devil fruit. What are the possibilities that the WG has engineered a lie in which supposedly two fruits will “make you explode and die without a trace.” Think about it, we haven’t actually seen this in action, there is no manga panel with a trustworthy source (unless you count Blueno) that represents a devil fruit user exploding due to proximity or consumption of another devil fruit, I’d even go so far as to say that maybe everyone’s theories avout BB are wrong, and that maybe he’s just the only person to realise that it’s fine to eat two fruits.
So what are the chances The five elders have two fruits? What are the chances Imu has two fruits? What are the chances that that is the WG biggest secret.
