Itsuki Koizumi

Itsuki Koizumi is one of the main characters of The Melancholy of Haruhi Suzumiya series.
== Charactah Account ==
A perpetual annoyance to Kyon, and toady to Haruhi. Also the wielder of (rather specialized) psychic powers and representative of a shadowy conspiracy of similarly-empowered people, who credit Haruhi as the source of their abilities. Like Yuki and Mikuru, he's here to observe Haruhi and, more so, keep her under control; he knows from regular experience the highly destructive nature of Haruhi's teen angst, and his "Agency" is tasked with keeping it under control.
Itsuki has an unflappable polite and affable manner and likes to go into long lectures and explanations with very expressive hand gestures. However, after numerous hints to this extent, in "Love at First Sight" he confesses to his Kyon that his polite manner is an act, and underneath he is often stressed out or even angry.
He excels at academics. Heavily intellectual, he enjoys arguing contradictory theories for rhetorical purposes. He often tells Kyon that he was "just kidding" about a grave statement he made earlier, making it ambiguous whether the statement was one of those strictly-for-fun theories or he is simply trying to disclaim responsibility for leading Kyon's thoughts in a certain direction.
