Haruno Sakura vs Yamanaka Ino
Background: Part 1
In the beginning of the series, Sakura is a Genin-level student of Kakashi Hatake's. Initially, Sakura's stamina and overall talent were quite below average, having had only used a few skills over the course of the series, the most advanced of which is dispelling genjutsu. Sakura's main strengths are her intelligence and her great chakra control. She was able to climb trees using her chakra on her first try while it took several days of constant training for Naruto and even Sasuke to manage it.
Inside Sakura resides the "Inner Sakura", which ridiculously seems to be much more ill-tempered than Naruto's demon fox. Inner Sakura seems to represent an assertive part of her personality and mostly serves as comic relief. Sakura's typical gentle responses are juxtaposed with the Inner Sakura's constant "Shannaro" (しゃーんなろー). The phrase has no literal meaning, but is usually translated as "Hell yeah", "Hell no", or "Damn it", depending on the situation (in English, it's translated as an angry and forceful "Cha!"). Inner Sakura is often attributed to being Sakura's defining ability, aside from her chakra control, much like Sasuke's Sharingan or Naruto's demon fox. Inner Sakura actually exists as a separate spirit within Sakura, which came in handy during her battle with her rival, Ino Yamanaka. When Ino hit Sakura with her Mind Body Switch Technique, she only suppressed the regular Sakura. As such, Inner Sakura, after a little prodding by Naruto, was able to emerge and force Ino to leave. Ino's lack of chakra also helped Sakura to resist. After this point, Inner Sakura only appears once in episode 197 of the anime, when Sakura fails to notice that a smoke bomb was set off the night before, and once in chapter 250 of the manga, when Naruto tries to refuse a mission assigned by Tsunade. Sakura, however, does occasionally exhibit traits that would have originally have been confined to Inner Sakura, though they are rarely seen (they become more frequent after the timeskip, a sign that Sakura is becoming more comfortable with herself and is showing her true nature more often).
Sakura's favorite foods are syrup-coated anko dumplings and umeboshi (pickled ume fruits); her least favorite food is anything really spicy. Her hobbies are quizzes and memorizing things and her favorite phrase is 勇気 ("Yuki", "Courage"), although this was once 一愛の十分の生命！ ("Issen ai no jinsei yo!," "A lifetime full of love") in the first databook. The latter was also featured in the ending song of episode 170 as a painting on her bedroom wall. She is also shown to be afraid of frogs.
New Personality: Part 2
After the timeskip, Sakura's personality has taken on a much more mature and even tone. Like most people when they come of age, she seems to be much more comfortable in her own skin than when she was younger, frequently displaying the more ferocious aspects of her personality formerly personified in the Inner Sakura segments, instead of just responding within her timid restraint. Jiraiya comments that she is becoming another Tsunade upon first seeing her.
Sakura has developed some quirks about how others view her appearance. When reunited with Naruto, she asks him if she looked more like a woman in a flirting way. Clueless, Naruto remarks that she looked no different, annoying her. On two separate occasions, Sakura has beaten up Sai over the issue, once for calling her 'Hag', and a second time when Sai 'complimented' Ino by calling her 'Beautiful' (Sakura had expected Sai to insult Ino).
Sakura's first impression of the new Naruto was that of a more mature person; she was sorely disappointed to discover he was still somewhat lacking in that department. Despite this, she does see that he has mostly changed for the better, and they are very close. They are able to work together much better than before, passing their second bell test due to their excellent, if somewhat unorthodox, teamwork. She still insults him, but in a much more playful manner than before. When Naruto defines one of their outings as a date, Sakura, still furious over the maturity letdown, replies "Fine. As long as you're paying." She is more concerned for his well-being, especially since he's a target of Akatsuki and under constant danger of death. She has cried for him on several occasions, especially upon learning that if the Demon fox is extracted by Akatsuki, Naruto will die. Yamato tries to give a clear description of these feelings at one point while Naruto is unconscious, but Naruto wakes up and interrupts him before he can say anything significant.
The state of her feelings for Sasuke are still unclear and conflicting, though she still seems to care for him, as she hits Sai when he insults Sasuke. Even with those feelings, during the Grass Country arc, Sakura looked at Sasuke with hostility and tried to attack him. Needless to say, for both herself and Naruto, Sasuke is still a very touchy subject, and both have a moment of comically-exaggerated gloominess when Kakashi mentions him during the second bell test. However, over the past two and a half years, Sakura has become more confident and less self-conscious around him; she is even willing to attack him to protect her friends and bring him home. In a later chapter, she sheds a tear over a picture of the former Team 7. During the funeral for Asuma Sarutobi, she is seen next to Naruto as he stands with a distraught Konohamaru.
Background: Part 1
Ino Yamanaka was a Genin assigned to Asuma Sarutobi's Team 10. With her teammates, Shikamaru Nara and Choji Akimichi, they make up the 2nd-generation Ino-Shika-Cho Trio. At first, it seemed as though Ino disliked both Shikamaru and Choji (Shikamaru for being dull and unpopular, and Choji for being fat), but she actually holds a strong bond with both of them. Ino is the daughter of Inoichi Yamanaka and part of the Yamanaka family, who owns a small flower shop in Konoha. Part of her bond with her teammates might come from her father, as he was teammates and good friends with the fathers of Shikamaru and Choji. She, Shikamaru, and Choji wear the same type of earring: a small silver hoop. At her graduation, she graduated as one of the best kunoichi in her class. She is talented in the way of the flower (Ikebana) as well as mind-altering jutsu. She is the rival of Sakura Haruno.
Her favorite food is small tomatoes and pudding. Her hobby is shopping and her favorite phrase is 花言葉の数々 (Hanakotoba no kazukazu, "The many words/meanings of flowers"). Her personality is outgoing.
New Personality: Part 2
Ino makes her Part II debut in Chapter 284 showing up just after Choji and Shikamaru fought Sai, yelling because Choji was late for a mission they were both leaving on with Asuma. She is seen wearing a short button-up top and skirt. She has apparently done away with the full-body bandages she wore and has also grown her hair once again. Like the other rookies during the timeskip, she has also achieved the rank of Chunin. She doesn't wear her ninja headband around her waist anymore as she previously did. In fact, it isn't visible at all.
Ino first meets Sai when Team 10 pays a visit to Kakashi in the hospital. Immediately, Ino recognizes the resemblance between Sai and Sasuke and develops an infatuation for the new face. Her sudden feelings are only strengthened further after Sai gives her the nickname "gorgeous" or "pretty lady," which is seemingly a compliment on her appearance. In actuality, Sai was simply complimenting her out of fear of a similar violent reprieve to his calling Sakura "ugly".
Later, she and Choji come to help Shikamaru and his team against Hidan and Kakuzu. It is mentioned, that she is able to use Medical ninjutsu, though it is not known if she is a qualified medic-nin like Sakura or possibly acting as a combat lifesaver. Ino was told to use some medical ninjutsu to improve Asuma's condition. However, Asuma knew his time was up, and instead gave Team 10 some parting words — To Ino, Asuma says that her spirit is strong and is a helpful child, so she should take care of Choji and Shikamaru, who are awkward. He also tells her not to lose to Sakura in ninjutsu or in love, to which she said yes. Then, after taking his last cigarette, Asuma passes away in front of her.
She and Choji attend Asuma's funeral. After the funeral, she, Shikamaru, and Choji pack up and go after Akatsuki. When Tsunade attempted to stop them, Kakashi offered to accompany them as team leader and the four have left to continue their mission.
After Shikamaru explained his strategy to everyone, she locates Hidan and Kakuzu by controlling a hawk with her Mind Body Switch Technique. During the battle, Ino plays the role of observer. After rejoining her teammates, Ino suggests using her Mind Transfer Jutsu to take over Hidan, but Shikamaru declines the idea, since the chance of her missing would be too much of a risk to take.
So which will it be..the blossom or the mind walker?
