Born to a cadet family of the Haninozuka clan, the Morinozuka family, Takashi assigned himself to be Hunny-sempai's companion when they were quite young. He is the only Host Club member who was not specifically targeted by Tamaki (as far as we know), having joined along with Hunny; however, his tall, dark, and handsome combo makes him a very popular host.
Personality
Mori-sempai is quiet and tends to react instinctively to things around him, earning him the designation "wild" (which in this context is similar to the "noble savage" concept). He is extremely loyal to Hunny-sempai, and has a mild soft spot for Haruhi, although it doesn't appear to be particularly romantic in nature. During Hikaru and Kaoru's dilemma over their feelings for Haruhi, Hikaru went to Mori-sempai for advice. Mori-sempai is probably also the only member to never be phased by Tamaki's antics, Kyouya's implicit threats, or Hikaru and Kaoru's pranks.
