Sai begins as a shady shinobi who concealed everything behind a grin. He was concealing this information about himself.
Sai is a character who doesn’t appear in Naruto until Part Two, after the audience has had several hundred episodes to get to know the other members of Naruto’s group. After Sasuke departs from Hidden Leaf Village and after Naruto returns from his three-year training stint with Jiraiya, he takes Sasuke’s spot in Team Kakashi.
In contrast to Sasuke, his past and interactions with Sakura, Naruto, and Kakashi give him a unique place on the team and a unique experience for the characters, pushing them to adapt to and work with a very different sort of ninja.
10/10 Root’s Training
Sai spent his formative years honing his skills with Root, an extremely specialised branch of the Anbu, a group of ninja that specialises in rounding up wayward ninja by murdering them. In particular, Root trained its ninjas to be emotionless and to follow instructions without question. This relieved them of the pressure to complete difficult or immoral assignments. Sai and the other ninjas in the gang were moved when Root’s creator, Danzo Shimura, who was perhaps the least likeable character in the series, passed away.
Relationship with Kakashi: 9/10
Kakashi was a previous member of Anbu, much like Sai. They have a unique connection and relationship as a result of this. Sai address Kakashi as “senpai,” which roughly translates to “senior” in Japanese. This is a token of esteem and appreciation for Kakashi’s ninja training. Sai is also set on facing Kakashi at some point, perhaps to demonstrate his abilities as a ninja and to demonstrate how much he has learned, developed, and strengthened.
His Personality: 8/10
Sai has spent the most of his life out of touch with his own emotions due to his training with Root. He is instructed to push them aside and not pay them any attention.
He keeps some of his training and some of the personality qualities that grew out of this even as he learns to reconnect with them. He is very obedient and submissive, prepared to accept directions, and he does it without hesitation.
7/10 His Sibling Shin
Sai did have a Shin when he was younger who he regarded as his sibling. They were both taught to have no emotions and no personal ties since they were both members of the Anbu’s Root division. Nevertheless, they did get close and their connection became nearly familial. Danzo ordered Shin and Sai to fight to the death in order to put an end to their feelings, but as Shin was already sick and about to pass away, he instructed Sai to inform Danzo that he had won.
Pays Attention To Detail: 6/10
Sai’s training and reserved demeanour have enabled him to have a keen eye for detail, which is one of his major strengths and a huge asset to Team Kakashi. He may help his colleagues by seeing threats that they haven’t by having the ability to see past fighting tactics. Beyond that, this makes him an excellent buddy. He can silently back them even if they aren’t being honest with him since he can tell when people are lying and how they really feel.
Wants To Rediscover His Emotions (Score: 5)
Sai has come to understand that having emotions is a unique aspect of being a person after spending time with Naruto and Sakura. Because of how they interact and communicate their emotions with one another, he understands why they are so close and have so many significant connections. He is trying to recover his feelings so that he may have the same sorts of connections that they have as he becomes closer to them as friends.
4/10 Speaks Immediately
Sai isn’t always the most sensitive to other people’s sentiments since he hasn’t spent a lot of time with friends or other people. He believes that being truthful is the most important thing he can do for his friends, and at first he struggles to distinguish between being truthful and being impolite.
He needs to realise that being nice doesn’t always include saying precisely what you mean all the time.
3/10 Has Friendship Issues
He doesn’t truly grasp how friendships operate because of his training with Root. Because ties make it more difficult to complete a fatal task, particularly when loved ones may perish in the process, he has been instructed to not think too much about other people or to take into account how and why they develop. Since Sai doesn’t fully see why Naruto has such strong emotions for Sasuke, it is a topic of friction between the two of them.
His Hobbies 2/10
It’s difficult to see any of the Naruto characters having actual interests. It is impossible to conceive that any of the characters have spare time since they are so busy with training and assignments. Sai does, however, have a few interests, but it is still difficult to see him having the time to pursue them. His hobbies include calligraphy and drawing.
Tenth His Wife
Sai marries Ino despite the fact that he first finds her unattractive, and the couple goes on to conceive a son they call Inojin, revealed in the manga’s last chapter. Aside from their tumultuous beginning, the most intriguing aspect of their relationship is the fact that Sai genuinely adopts Ino’s name once they are married. Only he has done so among the series’ male characters.
