Personality
As a child, Shizuku is shown to be a naive and sweet girl who cares a lot for her brother Ikki. After Ikki left the house, Shizuku's personality changed completely, she started to hate people and became resentful of them especially her family who she views as the people who drove Ikki away from her. It was also due to this that Shizuku decides to become a sister, family and lover to Ikki, giving birth to her obsession towards Ikki.

History
Ikki's younger sister, and as a child, Shizuku is the only family member of Ikki other than Ryouma to have never discriminated against him nor was she aware that her brother is being discriminated by her family, resulting in their close relationship.

After Ikki left the house, Shizuku was shocked and sadden over her ignorance to see her family showing no concern over Ikki leaving as he was viewed as non-existing to them. This event eventually resulted in Shizuku hating and distrusting other people and her extreme attachment towards Ikki.

It is later revealed that Shizuku had always had a distaste for humans, ever since she was a child, as they would usually bend to power, as she would usually get away with anything she did, because the adults used their power to make it so. This however eventually led to her first time meeting Ikki as he was the first actual human to not bend to adult power, and told her what she did was wrong.

New Term, Reunion and Rebellion
Shizuku, on her first day at Hagun Academy, is first seen embracing her brother lovingly, kissing him in front of everyone much to the shock of everyone present with Stella stepping in to keep Shizuku away from Ikki. Shizuku disliking the interference proceeds to argue with Stella and was shocked to learn that Stella is Ikki's "slave". Denying the fact, Shizuku brings out her Device and fights Stella as they ended up destroying the entire class room, which caused them both to be placed under house arrest for 1 week.

Following that incident, Shizuku is seen in her room with her roommate, Nagi Arisuin, who comforts her and helps her with her make over for her outing with Ikki. She then invites him along, as the outing was already ruined with Stella inviting herself, and Nagi would be able to give her support, when needed. The next day, Shizuku shows up with Nagi, meeting Ikki and Stella who were waiting for them. Shizuku then heads to the mall with them. As the four of them walks around the mall while waiting for their movie to start. Shizuku is then left alone with Stella, when Ikki and Nagi went to the bathroom until Rebellion shows up.

Shizuku is next seen with Stella, being used as hostages, with the other hostages. When Stella stands up to protect a woman and her child, Shizuku proceeds to make her preparation in making a barriers, messaging her brother and Nagi beforehand as Shizuku signals the counterattack by activating her Noble Art, allowing Ikki to make his move and defeat Bishou. Shizuku is then asked by Ikki to heal Bishou as he will probably bleed out. Shizuku agrees but is interrupted by a member of rebellion, who was hiding in the crowd with a hostage at hand. Now with the advantage, Bishou tried forcing Shizuku to heal her. This however became void, as Bishou and the rebellion member is shot down, by Shizuya Kirihara.

Debut Battle
One night after the Rebellion incident, Shizuku enters her first Selection Battle being victorious. She was then seen cheering for Ikki during his match against Kirihara. When Ikki was taken to the hospital for emergency aid, Shizuku decides to stay behind to allow Ikki and Stella have their own private time.

Impossible Victory, Decisive Battle, and New Beginnings
Two days after Ikki is victorious against Kuraudo, Shizuku learns about her next opponent for the preliminary round, Tohka Todo. She then goes to the training grounds, of the school, where she defeats fifty opponents with ease, not having much of a challenge against them.

Raikiri vs Lorelei
Shizuku then goes to the arena, where she faces the strongest knight in the entire school, Tohka Todo. Shizuku tries to fight Tohka through strategy and cunning, and although gallant, her efforts were for not as she was easily overpowered by Tohka and her noble art Rakiri. Shizuku then wakes up in the infirmary. She is then hugged by Nagi, who tells her that her brother was proud of her efforts. With the frustration of loosing the match and hearing what Nagi said, Shizuku begins to cry, while holding on to Nagi tightly.

Siege, Reunion and Trap
Shizuku is then seen in the student council room, after being invited by Tohka, talking with Tohka, who wanted Shizuku to convince her brother, Ikki, not to fight in their battle tomorrow, knowing how injured he will be. Shizuku had decided to not answer, wanting the night to think it over.

Shizuku was then seen greeting her brother at the gate, and had told him that, although she is against him continuing to fight, she knows that him fighting against Tohka would be best for him, encouraging him to keep on fighting instead.

She had then sat in the stands, with Stella, cheering for Ikki, as Ikki had fought against Tohka, although she was scared at the possibility of her brother dying in this battle. When Ikki had won, Shizuku was still frozen, and was unable to go congratulate her brother after his victory.

Training Camp and Scheme
Shizuku helps in the healing with the training camp, during the training camp for the Seven sword art festival.

During the night of the final day, Shizuku and Nagi had shared a drink and Shizuku points out that this was the first time had actually opened up to anybody, much to Nagi's surprise.

Akatsuki Strikes
Shizuku while on the bus back to Hagun, along with the participants for the festival, learns that Nagi is an assassin for Akatsuki. Shizuku points out that it didn't make any sense for Nagi to reveal himself now, leading to others to believe in Nagi.

They had arrived to a destroyed Hagun Academy, and were able to defeat the invading Akatsuki members. Nagi is then struck by Amane and then it is revealed that the Akatsuki members they had struck down weren't actual ones but instead wooden puppets made by Sara. Shizuku chases after Hiraga who had taken Nagi's unconscious body to Akatsuki academy, being helped by Ikki.

Shizuku leaves Ikki to fight against an unknown powerful swordsman, as she confronts the one armed swordsman Wallenstein. Shizuku was outmatched for most of the fight and Wallenstein was able to actually cut her in half. However, Shizuku reveals her new noble art, Aoiro Rinne, which allowed her to turn her very being into water, and was even able to manipulate the air that Wallenstein breathed, causing him to actual drown on land. She then finishes Wallenstein by destroying his very insides, saving Nagi from a terrible fate.

Shizuku, after the incident, learns the some members of Hagun academy's participants for the seven sword festival had dropped out, allowing room for her to participate. She gleefully accepts the invitation and was now a formal participant of the Seven sword art festival.

Party Crashers
Shizuku joins her brother in a party, which was held for the representatives of the seven sword art festival. There she met two Akatsuki members Sara and Rinna, who seemed both a bit to weird for Shizuku to actual consider to be terrorist. After the two had left the party Shizuku and Ikki were then met with Yui Tatara, who is someone with malicious intentions. This is proven as Shizuku was nearly harmed by Yui, who tried to feed her meat with metal blades in it. She is saved, however, by Ikki who nearly fought with her. The confrontation however, does not happen as other representatives intervene, causing Yui to leave in disgrace.

Dinner and confrontation
Shizuku, Ikki and Nagi are then invited to lunch by Yuudai, the seven sword king himself. There they met Kiriko, one of the representatives at the festival, who joined them for lunch. After lunch Ikki seperated from the group leaving Nagi, Shizuku and Kiriko. Shizuku is confident that her brother will beat Yuudai but Kiriko soon dismisses such idea, she then explains to Shizuku why.

Battle of Kings
Shizuku and Nagi are seen cheering for Ikki from the stands. Kiriko then meets with them, telling them that Ikki seemed nervous, causing Shizuku to remember what Kiriko had said to them, being that Yuudai was fighting for his little sister, who was unable to speak because of an accident she believed she caused.

Shizuku at the start of the battle became worried that Ikki was not going to win, believing the thing that had stopped his assured victory against Yuudai was Punch eye. That, however, was not the case as Ikki was simply having trouble using Edelweisse's own swordsmanship he didn't know. The tide of battle soon changes causing Yuudai's little sister to leave, not being able to bare seeing her brother in pain. Shizuku chases after her and meets her in the hall, convincing her that she needed to be strong for her brother causing Koume, Yuudai's little sister, to come back and watch her brother. Shizuku then cheers as her brother is able to defeat Yuudai once and for all.
