Itsuki KOIZUMI main image

Itsuki Koizumi is a charismatic high schooler who always has a smile on his face. Whilst he always speaks and conducts himself in a polite, proper manner he is quick to challenge Kyon's views. Itsuki always approves of Haruhi's often outrageous schemes, and his speculative nature lead to logical explainations for the inexplicable situations the SOS Brigade often find themselves faced with.

Useless bastard that drags the Anime down with his very existence.

And for those of you that say he's useless, that's really not the truth. He is the one who explains everything that happens to Kyon, and we wouldn't understand a lot about what was happening if it weren't for him.

SO BACK OFF! (lol)
