Sonou Mori (森園生) romanized as Sono Mori in the light novels) is a character in the Haruhi Suzumiya franchise.


Mori made her debut in Remote Island Syndrome Part 1 as the maid of a distant relative of Itsuki Koizumi, Keiichi Tamaru. However, when Yutaka Tamaru seemingly murdered Keiichi, Mori became a key player in the scheme. However, it was revealed that the "murder" was a setup by Itsuki and his Agency to entertain Haruhi.

Mori reappears in "Snow Mountain Syndrome" when she and Arakawa serve the SOS Brigade. She also helps play out the "Where Did the Cat Go?" scenario with the reenacted fake murder.

Mori makes a final appearance in The Intrigues of Haruhi Suzumiya, in which she helps Kyon recover Mikuru from Fujiwara and Kyouko Tachibana. She leads the recovery, and Kyon notes that she has a very terrifying smile that will compel anyone to listen, and thus concludes that Mori has a very high position - or is possibly the leader - of the Agency.

In The Surprise of Haruhi Suzumiya, Kyon was informed by another esper that Koizumi himself was the leader of the 'Agency'. Kyon mentioned to Koizumi that, despite her being careful to refer to him without an honorific, he thought that Koizumi was her superior.


  • The name Sonou means "garden" (園) (sono) and "raw, crude" (生) (u).
  • Sonou's surname Mori means "forest" (森).
