AI Itsuki Koizumi (The Melancholy of Haruhi Suzumiya) Voice

Itsuki Koizumi (古泉一樹 Itsuki Koizumi) is a main character in the Haruhi Suzumiya franchise (original light novel series, TV anime, and manga). He is the fifth person to join the SOS Brigade, and was recruited by Haruhi Suzumiya because he fit her idea of a "mysterious transfer student", after he was transferred into North High. He later reveals himself to Kyon as an esper, working for a group he only acknowledges as the 'Agency' (translated as The 'Organization' in the anime). According to Kyoko Tachibana, he in fact founded it. Though he was sent to North High by the 'Agency' to observe Haruhi, he believes that it was Haruhi's will that really brought him there. Due to his "distinguished service and dedication to the brigade," Haruhi promotes Koizumi to Deputy Chief. He is voiced by Daisuke Ono in the Japanese dub and Johnny Yong Bosch in the English dub.
