Shiho is an upbeat cheerful girl who appears to be attracted to Shikamaru Nara. She deeply blushes as Shikamaru leaves to seek help with the code. Knowing that Shikamaru said he would return if he found out any new information, Shiho refuses an offer to go home from her boss. Instead she fixes herself up in a mirror, intending to see Shikamaru again when he returns. Shiho also blushes when Shikamaru accepts her offer of accompanying him back to Tsunade's office. The side text on chapter 407's cover page, which Shiho appears on, makes mention of how excited and nervous she gets around Shikamaru.
edit Part II
Hunt for Uchiha arc
Shiho is first shown as one of the ninja assigned to Konoha's cryptology unit. She informs Shikamaru that they cannot decipher the code without a key. She tells him that someone who was close to Jiraiya might be able to help crack the code. After helping to crack the code, she then accompanies Shikamaru and the others back to Tsunade's office.
Invasion of Pain arc
Shiho is later seen helping Shikamaru and Sakura figure out what the now cracked code means. When Pain invades Konoha, she is seen speaking with Shikamaru with his father behind him. She survives Pain's large scale attack on the village along with Shikamaru and Shikaku.
Shiho is level-headed, and despite appearing young, quite competent as a decoder. She helps both Shikamaru and Naruto in code breaking and is able to figure out Jiraiya's code based on the information she was given. She also appears to be quite intelligent, offering sound advice when Shikamaru and Sakura discussed the meaning of Jiraiya's message.
