AI: The Somnium Files Wiki


Congressman So Sejima (世島 綜, Sejima Sō) is a character featured in AI: THE SOMNIUM FILES.

So is a member of the post-World War II generation. He grew up poor, which gave him two things: his motivation for seeking power and wealth and his vindictiveness toward the upper class. By his 40s, he had become a prominent political celebrity within Tokyo. He had a wife who died in labor giving birth to their son, Saito Sejima. He lives alone in an old Japanese castle, accompanied only by his bodyguards and personal attendants.

In AI: THE SOMNIUM FILES, he is a person of interest in the murder of Shoko Nadami, and the New Cyclops Serial Killings as a whole.

Trivia[]

  • In the Famitsu Interview, Kotaro Uchikoshi and Akira Okada state that following the Ota Route (and indirectly the Mizuki Route), So Sejima, now living under the identity "Iris Sagan" in her body, eventually becomes Prime Minister of Japan, using Iris's looks to climb the political ladder. The interview notes that this statement was made as a joke among the two.[1]
