He is often seen with a sucker in his mouth.

Personality
He is willing to use corpses for his Coffins and even use live humans for his research, if him wanting to use Accelerator as a specimen is something to go by.

He later berates Nishio for blaming him regarding the prototype Coffin failing against Accelerator. He later kills Nishio using Qiong Qi after he discovers that he lied that he has captured Estelle. When Estelle arrives with Accelerator in the warehouse, he divulges to her that their plans are advancing, and later tells Accelerator that he would like him to be a specimen of his. He later has the mecha leave as it is too soon to fight Accelerator, easily deflecting his wind attacks using the mecha.

Quotes

 * (To Nishio, from Accelerator Chapter 2): "Fragile justice is an evil that disturbs the order. An evil must be destroyed even if its one of us. Our organization is meant to bring perfect justice to Academy City."
