Among the five families, only Lota remained on Jordan's side.
Lota said, "Why are you so sure that Jordan did this? He was injected with the Mirakuru serum, but this doesn't mean that he is invincible. How could he have gone to the Park and Miyamoto family territories and killed their leaders? How could he leave unscathed? Aren't you overestimating Jordan's strength?"
Everyone had actually discussed this point when they just arrived.
The Park and Miyamoto families were heavily guarded. No matter how strong Jordan's body was, it was impossible for him to kill them easily.
