Chapter 1053. Aramaki says: "You did good. When i bring him this kid head", boom Strike 1
There's literally no statement of the reason of Aramaki going to Sphinx because of making hostages, you hallucinated this. Strike 2
If they were still recovering, explain why did THEY jumped into Aramaki? Strike 3
Or show the panel to validate your point
So should do the work of reasearch for you like i were a clown, just because you're to search or actually the manga? Do your search Lol
Also, why don't you post the panel of Aramaki's using hostages in Sphinx Island lmao
