### Nishijou Takumi (西條 拓巳)
A second-year student at Suimei Academy.
He is withdrawn and not interested in the 3D world and its inhabitants.

His interests lie in watching anime, playing eroge, and Empire Sweeper Online, an MMORPG where he's the top player "Neidhardt".
He suffers from intense delusions as a result of his apparent schizophrenia and the extremely secluded lifestyle he lives as a shut-in.

Chaos;Head Noah: [spoiler]It is revealed that Ayase doesn't see the world the same way as other people, probably since she became a Gigalomaniac. She always sees a world with a red sky full of people with malice and negative delusions, and the reason why Ayase was able to know immediately that Takumi was a Gigalomaniac like her the first time she sees him, is most likely also because of that.[/spoiler]
