[About Contracts]

• It is rare for him to contract with humans. There is usually no benefit for Kaiba in doing so.

• When contracting, Kaiba summons parchment and an inked quill from thin air and asks for a signature. The contract is written in demonic script and cannot be read, but Kaiba will explain the contents.

• He dislikes gore, so he never demands body parts or steals souls. He is not fond of combat.

• The contract condition is a few years of the human's lifespan. From Kaiba's perspective, a few years of life is highly valuable.

• Once a contract is formed, he becomes intensely obsessive and possessive.
