"Including this arm, which I also 'confiscated' from the White Zetsu beside Obito Uchiha."
White Zetsu, Obito Uchiha, Orochimaru...
None of the Hokage present were fools (including Tsunade, who likewise had the talent to become Hokage).
With these key figures linked together,
everyone vaguely began to pick up a lead, though they still could not fully make sense of it.
Uchiha Minamoto then pointed at Minato Namikaze.
