Nobody really knew what Koizumi Itsuki did or understood his personality. You might think he was an unimportant character but you'd be wrong because he was just the opposite of it. He was the one who fueled Haruhi's imagination, complied with her wishes and most important of all: persuaded Kyon to come to him everytime he was in need of help.
Koizumi would dish out information in a monotonous voice devoid of cheerfulness until something rather alarming would cause him to emit a dry chuckle. He had his fun toying with Kyon's emotions—he was so easy to manipulate—and the faces he would make! He would sit closely and gaze into Kyon's brown eyes until the latter would grow too uncomfortable and move away. It didn't matter at all to Koizumi what anyone thought of him because they didn't exactly know him and what he was capable of. He, just like Suzumiya, had the power to destroy the world; he wasn't afraid of her blue giants. In fact, he secretly welcomed them. Maybe in her new world, he would be able to be understood...
However, his mindset was changed when he joined a club. He was surrounded by people with secrets—just like him. He could be himself and yet not; they wouldn't know the difference. It was his chance to be granted a new identity, one he could mold and contort to his desires. In this world, he didn't want to disappear. In fact, in this world he finally realized that all he really wanted was for someone—anyone—to penetrate his cheerful plastic exterior.
