OH HEY GILLIAM
You’re looking… different…
DID YOU JUST GET AN ENTIRE MAKEOVER BECAUSE OF WHAT HYOUBU SAID??
well the mask is probably due to the explosion but
I guess Gilliam decided he wanted to look like the phantom of the opera or something to go with his new bird mask
Black Phantom and Bird Phantom.
As awesome as it would be to call him Birb Phantom and institute the headcanon of Hyoubu’s life-altering fashion critiques, I don’t think we can say that this is Gilliam just yet. Although the regal attire certainly does fit him, Birb Phantom here could just be a hypnotized esper and the cracks on his face could probably be explained by one of Gilliam’s many experiments since the last time we saw him. For example, it’s possible that the cracks could be a by-product of Gilliam searching for a way to control espers without using Yuuri.
TBH I wasn’t entirely sure it was Gilliam at first either… Like, I stared at the panel really hard to make sure and compared it to older panels of Gilliam and it seems pretty close. As for the cracks, I thought they were the result of gilliam taking in the childrens power to get stronger… I dunno, it’s been a while since I re-read the series but that was my understanding.
But yeah, you’re right that it hasn’t been confirmed as Gillian. He just seemed like the most likely option IMO
