Here is Koro Sensei in his last form with unbreakable shield during Assassination Island Arc .
Koro Sensei is the modified human/alien teacher from Assassination Class anime. He has an octopus figure & body with a super strength that could annihilate the whole world.
During Assassination Island Arc, the students successfully force him to use his last defense, the unbreakable shield which turns him into a ball but left him immobilize.
The model includes 2 of Koro Sensei head in pink and yellow.
Model is simple enough to make and cost only 1 paper to print. It looks great on my table
