The world was already on the brink, and Kenji's forced Warlord status was a sign of the Government's panic. The news of Portgas D. Ace's capture was the match that lit the powder keg.
Kenji sat in the Sunny's lounge with Robin, gazing at the bounty for Ace.
"The Summit War is imminent, Robin-san," Kenji stated grimly. "The greatest conflict this world has ever seen. Whitebeard will move heaven and earth to save his son."
Robin looked at him, her hand resting over his. "And you will be there, Kenji-san. As a Warlord. Will you fight?"
"I will fight for the survival of the future," Kenji confirmed. "Which means ensuring Ace and Whitebeard survive this catastrophe. Luffy cannot be the Pirate King without his brother, and the balance of the world needs to shift."
Kenji used his Omniscience Haki to subtly manipulate the communication lines of the world's most powerful newspapers. His goal: slow the official execution date.

Kenji exerted a highly localized temporal dilation field around the communication equipment handling the execution news, delaying the official broadcast to Whitebeard's forces by several crucial days. This minor shift would buy Whitebeard the necessary time for maximum preparation, ensuring a long, drawn-out battle.
The call came quickly: an emergency assembly of the Seven Warlords at Marineford. Kenji accepted, taking Robin with him under the guise of an "Archaeological Assistant," knowing no Marine would dare question the $3 Billion "Apex Warlord."
