Takashi Saitou

A peculiar man in a traditional Japanese garb and a fox mask who felt a "karmic connection" to Ii.

Catchphrase: "We'll meet again, if we have a connection."

During his first conversation with Ii, he states that he's standing outside the story; he's been exiled from karma; he's been expelled from causality. He also calls himself "half-assed and vague" as a result of past events and his current place outside of the story. Because of this, he has to use other people (mainly the Thirteen Stairs) to act in his place.

On his second conversation with Ii, he remarks that the "soul" within Ii is reminiscent of his own as Humanity's Worst, and his goal is to witness the Dying Epilogue, which is the idea that all events that has occurred will eventually lead to one point regardless of how related or unrelated the events, coincidences and meetings are when leading up to that point.

Before leaving the clinic, he claims Ii as his enemy and states that Jun Aikawa is his daughter

Prior to his first appearance,

Ii makes a remark when speaking with his old teacher, Miyoshi Kokoromi, about how he heard through the grapevine that a Japanese person with a strange name was a candidate for the Seven Fools. Tomo Kunagisa also remarks about a "genius machinist who brought electronic darkness onto the entire world with a mere 16 byte program." He is "One that far surpasses Cluster that once existed, the existence called Desert Fox-"
