He is now seen as the evil villain but in reality he is just a lost kid he does very villain stuff

At the new part/arc he finally realizes his wrong doings and knew he couldn't go back so he proceeded with his plans to do the GMS(Great Monster Stampede) and he failed

Line: "such a beautiful sight well be freed from our shackles... With death!"

The stampede was beautiful the monsters going to the world destroying the barrier and helping us become free from these shackles and be the best part we could ever be!

Arc 4↓

He passed out now half human half yaknir

"What have I done! I have become the thing I hate I am the embodiment of a monster!" He is crying

He needs help as he walks around with one eye missing he decided to wear a eye patch and mask to hide his face becoming like ken kaneki a mixed he slowly becomes human but he still has parts of a yaknir he has a tail containing all the power of it and the government manipulated him more

He starts another GMS but this time the government is dying they scream in pain and they die he is happy and he sits on a building looking at the outside world and he feels the air and he puts himself in a cross † pose and let's the air feel over him "such a beautiful world and breeze" he says as blood and screaming is heard in the background and multiple AA appear kill the monsters on the verge of living and Tomi is laughing
