Sakura Hiden: Thoughts of Love, Riding Upon a Spring Breeze (サクラ秘伝 思恋、春風にのせて, Sakura Hiden — Shiren, Harukaze ni Nosete, Viz:Naruto: Sakura's Story) is an original story written by Tomohito Ōsaki and illustrated by Masashi Kishimoto. It is the third book of the Naruto Hiden series.
None of the eight chapters in this novel has a title; however, each chapter is divided into 2-5 subsections.
Prologue
Sakura Haruno reflects on some moments she's had with Sasuke Uchiha: when she unintentionally insulted him shortly after the formation of Team 7; when she tried to stop him from defecting to Orochimaru; when he left Konoha to wander the world, but promised to see her again. Sakura wonders where he is now.
Chapter 1
After the Fourth Shinobi World War ended two years ago, Sakura assisted with healing those injured and displaced by the conflict. Although the adults recovered quickly and were put at peace by the end of hostilities, children struggled to recover from the stress of the War and the deaths of those they knew. In order to help them deal with this, Sakura and Ino Yamanaka opened a clinic within the Konoha Hospital that would assess and treat children's mental health. Following a progress report about their program, Ino invites Sakura out to tea with her, but Sakura declines because she has paperwork she wants to do. She later encounters Naruto Uzumaki and Hinata Hyūga on a date, and they also invite her to join them. She again declines, but realises that her friends are becoming worried about her heavy workload.
A week later, Sakura meets with the Hokage, Kakashi Hatake. He informs her that Sunagakure is interested in opening its own clinic for children and has requested that she and Ino help lay the groundwork. After she leaves to prepare for the trip, Kakashi meets with Sai and tells him about two separate attacks by unknown perpetrators against the Fire daimyō and Homura Mitokado. Although nobody was badly hurt and there's no proof the two attacks are connected, Kakashi wants Sai to investigate both incidents by himself.
Sakura meets with Tsunade before she leaves for Suna. Tsunade tries to encourage Sakura to take it easy, as the clinic's growing success means that there are other people able and willing to do some of the work. Sakura takes the opportunity to ask how to make men take notice. When Tsunade can't offer her any specific advice, Sakura asks that Tsunade bet against her love life, hoping for Tsunade's bad luck to play in her favour.
Sakura and Ino start gossiping when they depart for Suna and Sakura learns about Shikamaru Nara's relationship with Temari, Chōji Akimichi's relationship with Karui, and Ino's feelings for Sai. While Ino debates how to express herself to Sai, Sakura wonders about Sasuke and herself.
Sasuke meets with a group of Suna missing-nin, offering to help them perform a coup d'état in Suna if they will first help him destroy Konoha. When the group's leader refuses to be subordinate to him, Sasuke kills him. A squad of Suna Anbu immediately begins attacking the group and Sasuke escapes in the commotion.
Chapter 2
Sai meets with an informant just outside of Konoha and sends him to investigate if some criminals listed in the Bingo Book are behind the two attacks. As he returns to the village, Sai is attacked by two masked individuals. Although each of the attackers has a cloak of tailed beast chakra, he is able to drive one of them off and capture the other. Sai starts questioning the captive, but when the man begins to respond a juinjutsu activates and his body blows up.
While taking a break during their trip to Suna, Sakura dreams that Sasuke meets her at the entrance. She wishes for the dream to become a reality, but she and Ino are met only by a Suna shinobi who escorts them to their conference with the village's doctors. Afterwards, however, they are summoned before Gaara, the Kazekage, who informs them that Sasuke has been to Suna.
Gaara repeats to them the conversation that Sasuke had with the terrorist group two days earlier, which he (who was surveiling the group anyway) witnessed with his Third Eye. Although he, Ino, and Sakura want to believe it was someone disguised as Sasuke, they can come up with no practical explanations for the man having Sasuke's chakra signature. Hoping to keep Sasuke's apparent plans a secret, Gaara asks Sakura to personally inform Kakashi of the plot against Konoha.
Chapter 3
During a meeting with the Fire daimyō to discuss the budget, Kakashi and Shizune try to secure additional funding for Sakura's clinic. Kido Tsumiki argues against them, believing the recent attacks against the daimyō and Homura call for increased funding to Konoha's Anbu. The daimyō defers to Homura, who decides to side with Kido.
When Kakashi returns to his office he is met by Sai, who tells him of the earlier attack he fought off. Both observe that the attacker's suicidal juinjutsu is similar to what Danzō Shimura used on his agents. This, combined with the fact that nobody but an Anbu could have even guessed Sai's assignment and thus known to attack him, convinces Kakashi that it is all part of a scheme concocted by Kido Tsumiki, a former ally to Danzō. Kakashi instructs Sai to focus his investigation on Kido.
Sakura and Ino deliver Gaara's message to Kakashi as soon as they return to Konoha. Kakashi is also convinced that the man conspiring against Konoha was a lookalike of Sasuke, but he has no reliable way of contacting Sasuke in order to confirm. He shares Gaara's recommendation to do nothing at the moment so that unsubstantiated assumptions can't be spread against Sasuke. Sakura returns home, frustrated by Sasuke's years of absence.
In a secret lab outside Konoha, Kido talks with his assistant, Magire. Magire speculates that Kakashi has figured out that they were behind the attacks on the daimyō and Homura. Kido is unconcerned so long as Kakashi doesn't realise the actual purpose of the attacks: to test out their synthesised tailed beast cloaks.
Chapter 4
Sai follows Kido's movements between his different hideouts for three days, but he has no way of getting inside any of them without revealing his presence. His informant requests a meeting and, there, reports a rumour about Sasuke: that he approached some arms dealers several weeks earlier seeking weapons for an attack on Konoha, and then killed the dealers when they failed to cooperate. He also reveals that, after the war, he saw Anbu collecting samples from the Valley of the End and the bridge where Sasuke fought Danzō. Sai pays him for this information and requests another meeting in the future.
Kakashi informs Sakura and Ino of the rumours about Sasuke's activity that have been reported by Sai. Ino is initially more concerned with what risks Sai may be facing, but Sakura steers things back to what the rumours mean for Sasuke. Since Sasuke was so instrumental to the victory during the Fourth Shinobi World War, the five Kage are still willing to believe it is not Sasuke planning against Konoha. However, if news of his actions gets out and public opinion turns against him, the Kage will be forced to do what they can to stop him.
Kido reflects on how successful his imitation of Sasuke is being. By having the impostor conspire with underworld elements and then kill them, word of Sasuke's seeming activities is spreading throughout the ninja community, despite the intentions of Gaara and Kakashi. Kido believes it is only a matter of time before the real Sasuke returns to Konoha in order to investigate the impostor, at which point Kido will be able to capture him.
Sakura wanders the village trying to clear her thoughts. She passes by the Academy and sees Naruto instructing a class of Academy students. He invites her to help the class with their sparring lessons, and Sakura finds it an effective stress relief. Afterwards, she tells Naruto the rumours about Sasuke. Naruto isn't concerned, confident that it's an impostor. He also points out that Sasuke must not be worried about it either, otherwise he would have responded to Kakashi's messages. Sakura realises he's right and is finally put at ease.
Sakura has drinks with Tsunade to try and figure out how the Sasuke impostor is able to reproduce Sasuke's chakra without his knowledge. Sakura theorises that samples of Sasuke's skin and hair that naturally fall off have been gathered in amounts large enough to extract a chakra signature from. Tsunade deems her idea plausible. Sakura runs into Sai afterwards and she tells him her theory, which makes enough sense to him that he asks her to accompany him to Kakashi's office.
Chapter 5
With Sakura's theory and his informant's earlier report about Anbu activity at the Valley of the End, Sai believes the Anbu – specifically Kido and Magire – are behind the Sasuke impostor. He also believes this would explain the tailed beast cloaks he encountered, with those being drawn from skin and hair samples taken from Naruto and other jinchūriki. Since Sakura, Sai, and Ino are apparently all investigating the same thing, Kakashi makes them a team; Ino dubs themselves "Ino–Saku–Sai". The three agree to continue their investigations and keep each other informed of their findings.
Kido is becoming frustrated by Sasuke's continued absence. Hoping to force his return, he orders his underlings to kidnap Sakura. When one suggests killing her to increase the chances of Sasuke's appearance, Kido responds they may do so at a later date.
Sakura and Ino return from an interview with Rock Lee, who saw Anbu near the Naka Shrine two years ago. On their way to meet up with Sai, Sakura sees two Anbu trying to take Sasuke into custody for terrorist activity. She goes to them to lend assistance, either to free the real Sasuke or apprehend the impostor, but discovers that it is all a genjutsu. She dispels it, but is immediately injected with a drug that renders her unconscious.
Sakura wakes up to find herself bound and imprisoned. She tries to break out when she remembers what's happened, but the drug she was injected with hinders her strength and chakra. Kido comes to visit her soon afterwards, explaining that he wants to draw Sasuke out with news of her kidnapping. Sakura is secretly curious about whether Sasuke would indeed come back because of her, but ignores this because she doesn't want to be used to hurt him. She tells Kido to kill her, which he promises to do only after Sasuke is captured so that seeing her death will make his Sharingan stronger, in turn making his planned synthetic Sharingan more effective.
While taking a shower, Sai is called to answer the door. He finds Ino there, who is embarrassed by his lack of clothes. She tells him that Sakura is missing and they assume she's been kidnapped by Kido. While he gets dressed, Ino contacts Kakashi and informs him of what's happened. He advises not getting anyone else involved in the rescue as that might only provoke Kido to kill Sakura. He also informs them that the Fourth Raikage is contemplating a Kage Summit to discuss reports of Sasuke's activity.
Chapter 6
Sakura keeps Kido engaged in the conversation by speculating that his synthetic tailed beast cloaks are supposed to help capture Sasuke. Kido confirms this, saying that the cloaks are at least effective enough to restrain Sasuke while they take his eyes. Sakura finds the various things Kido has synthesised unimpressive, pointing out the many minor flaws in the Sasuke impostor she saw earlier. Kido tests her claim by having the impostor tell Sakura he loves her. Though she's unsettled by the words — even knowing they're not from the real Sasuke — Sakura maintains it's a poor imitation. The conversation buys Sakura the time she needs to gather enough chakra to break free.
