Hints Aramaki is replacing Kizaru as the second strongest below Akainu:
-He captured Weevil who was hyped by Kizaru.
-Went to Wano by himself without asking permission to Akainu.
-Sneak attacked by Shanks while busy but wasn't allowed to fight them (only Akainu met Shanks in person before)
Fought Fujitora and the Revs, bandaged him up
Anything else? Let me know
