Kyon's own name as revealed at the beginning of some chapters is equally meaningful. Taira no Tadamichi (aka Usui Sadamitsu) is the real name of a samurai involved in a Japanese legend, who was from one of the four families that held the power behind the Japanese throne from the 9th to 12th centuries. The other three families were Fujiwara (the other time traveler), Tachibana (the other esper), and Minamoto (which was historically based in the same geographic region as Nishinomiya). As for the meanings of the names, Tadamichi can mean straightaway/honest/frank/fix/repair | person/alternative/direction and Kyousuke can mean great | law/rule/ceremony/code. Think how Kyon has affected Haruhi. It has also been discovered that Kyon is likely descended from Usui Sadamitsu and certainly owns what's left of their sword.
