he remember again when the cadaver of General Kanade being held on the city to began his funeral this make Naruto angry, Naruto see general Kanade as his grandmother and the great tutor.
this make the people angry on Sadera Empire there they want revenge, the emperor who pragmatic tell the people their will be the time when the Neo Uzu Empire will revenge the Sadera Empire.
the emperor knew that his fault that this make his closed friend died during the Battle to defend the Warrior Bunny.
as he watched the body being burn and become urn the Body of General Kanade being cremated in open field since his royalty lineage and second the achievement he got during various campaign.
Naruto who still grieving on his grandmother, began to become cold except to emperor and people around who close on him, since he knew that Naruto on General Kanade Impact him.
