Itsuki Koizumi (古泉 一樹 Koizumi Itsuki?) is a fictional character from the Haruhi Suzumiya light novel series; in the anime he is voiced by Daisuke Ono in the original version, and Johnny Yong Bosch in the English dubbed edition. Itsuki is the last member to have joined the SOS Brigade, having been recruited by Haruhi as a "mysterious transfer student". Itsuki was sent to observe and keep Haruhi emotionally stable, in order to protect the rest of humanity. Although he is an esper, which is exactly one of the sorts of people Haruhi desires to meet, Itsuki never reveals himself as such, at least, not to her.

[edit] Personality

Itsuki is constantly smiling and always speaks in a formal and polite manner. He is also prone to giving long and detailed explanations, usually illustrated by exaggerated hand gestures. Itsuki has confirmed to Kyon once that his outer personality is merely an artificial image he fakes in accordance to Haruhi's impression of him, and hints that his true character is something quite different, being "less pleasing" in the eyes of others. Maintaining his casual, constantly smiling self, however, is vital for keeping Haruhi's mentality balanced.

Out of the four Brigade members, Kyon is the least fond of Itsuki. He often finds himself annoyed with Itsuki's plastic smile, his willingness to acquiesce to Haruhi's outrageous schemes, playful teasing and his various forays into his psychological and philosophical theories (e.g., omphalos hypothesis, Anthropic principle, etc.). He is also distrustful of Itsuki's intentions, comparing him to Yuki Nagato when it comes to deciphering his expressions. Itsuki's fondness for speculation often causes him to produce explanations for situations involving the SOS Brigade, its members and related events. Ironically, Itsuki can only share his theories with Kyon and also enthusiastically plays different kinds of board games with him to pass the time, despite losing all the time, although Kyon suspects that he may be doing so on purpose.

Although Itsuki was named official second-in-command by Haruhi for providing the Brigade a place for their vacation/mystery investigation (Remote Island Syndrome Part I), this title appears to be little more than formality since, in every aspect, Kyon is still technically Haruhi's right-hand man.

During episode seven of the anime (Mystérique Sign), when the SOS members are trapped in a mimicry of closed space, Itsuki displays some of his esper abilities fighting the cricket Shinjin with Yuki Nagato. His esper attacks are named "Fumoffu" and "Second Raid", both references to the mecha anime Full Metal Panic!.

Itsuki is a member in a secret association which he simply refers to as the "Agency" (機関 Kikan?, "The Organization" in the English dub). The members of this society consist of special humans known as espers who gained unique ESP-like powers and special knowledge regarding Haruhi three years ago. Since then, they have been actively protecting humanity by fighting giant beings known as Shinjin (神人? Lit. "godlike person") within the closed spaces generated by Haruhi. Should the destruction of the Shinjin be left unchecked, the Closed Spaces generated would eventually take reality's place. He often gives his gratitude to Kyon for keeping Haruhi emotionally stable, and in turn, reducing the workload he and his colleagues are required to perform.

Despite the theory he advances in which Haruhi is the equivalent of God, Itsuki says that there are many differing lines of speculation about Haruhi within "The Agency". Itsuki himself does not believe in a singular God, although he reveals that he has colleagues that do. Apparently, most of the questions that he raises about Haruhi's true nature are philosophical in nature and do not necessarily represent his personal beliefs. Itsuki also reveals that the majority of "The Agency" advocates are observing Haruhi instead of doing anything that might provoke her.

Itsuki has also revealed that there are other factions that have not yet been revealed by Haruhi, and that "The Agency" is often in conflict with the other factions backing their respective agents within the SOS Brigade (not to mention various groups which have either not put in an appearance or appear to be enemies). For example, he suspects that Mikuru was chosen by the time-travelers for her beauty and for her ability to seduce Kyon, in order to control the group dynamic within the SOS Brigade, although Itsuki later suggests that he had been lying about this suspicion.
