Yeah
i know there is the alternative interpretation of "omnious" haki but i dont see that angle
Every time imu or, im assuming here, characters given by imus power with boosted haki (see xebec) it was displayed as strong, see the reaction to the haki of saturn
When imu arives, he shits haki, his teleportation circle is haki (unless im mistaken? It doesnt look like the black flames shown this chapter)
Like i fail to see how this is not a strength statement
