History
Alice comes from a small town in Eurasia, staying in a church with a nun and several children including her friend Yuuri. One day, her younger friends were kidnapped by a group of mob ordered by the mayor which resulted in the death of her best friend Yuuri. In a rage, Alice killed all the mobs emotionless but indirectly ended her friendships with her younger friends. While wandering alone, she ended up meeting Sir Wallenstein who offered Alice a position in Rebellion which she accepted under the terms of being handed a large sum of money.

New Term and Rebellion
Alice first appears inside her and Shizuku's room, alongside an angered Shizuku Kurogane over her issues with a certain princess who interrupted her and Ikki's moment together. Shizuku wonders if her love for her own brother was weird. Alice then gives Shizuku some advice over this issue and decides to give Shizuku a makeover. Alice is then invited by Shizuku, since her original plan was messed up by an intrusive Stella who invited herself along, wanting Alice to be by her side, as she gains confidence when Alice is around.Alice and Shizuku then meet with Stella and Ikki outside the front gate of Hagun Academy, where she introduces herself to the latter, shocking them. The group then heads to the mall, and visit restaurants while waiting for the movie to start. After finishing their lunch, Alice follows Ikki to the bathroom, wanting to know Ikki a little bit better and starts a conversation with Ikki, realizing that Ikki is too used to being hurt to the point he can no longer hear the screaming of his soul in pain. Alice sensing the surrounding then grabs Ikki and runs inside the bathroom as the sounds of shattering glass followed by guns and screams are heard.

Ikki contacts Kurono, who already knows the situation and tells them that Rebellion has hostages at the food court. Alice uses her Shadow Walk ability to transport Ikki and herself to the top level of the mall staring at the hostages and finding Stella and Shikuzu among them. Alice then stops an angered Ikki, who was about to go down, showing him the message, that said Shizuku was putting up a barrier. The conflict subsides as Alice points out to Ikki that Stella had taken care of the rest. Alice then gets the cops to arrest the members of Rebellion.

Debut Battle and Vow
Alice is said to have won her first selection match against an E-Rank within 10 seconds, although it is unknown what method she used. She then goes to Ikki's match and cheers him on as he fights Kirihara.

Lorelei vs Raikiri
Two days after Ikki's victory over Kuraudo Kurashiki, Alice interrupts, Ikki and Stella's intimate moment, after they were finally able to be completely alone for once. She tells them that Shizuku's tenth round opponent had been decided. She will face the student council president Tohka Todo, who was in the Top 4 of the last years Festival. Shizuku loses her match against Tohka, despite showing an amazing amount of talent and skill. Alice later comforts Shizuku in her hospital room, saying that she did great and that it's okay to cry and show bitterness over losing.

Siege and End of Selection Battles
Alice is mentioned in having to fight in her own selection battle and is unable to go to Ikki's match against Tohka. She is then announced one of Hagun's representatives in the 62nd Seven Stars Sword Art Festival, but does not appear at the ceremony as she has to convey the information of the participants for Hagun Academy, to an unknown source who is a part of an underground group called Akatsuki, as well as revealing herself to being one of their members.

Training Camp
Alice participates in the training camp, bringing along Shizuku who is on medical staff. Alice is later seen on the last night of the training camp stabbing Kagami in the back with her Darkness Hermit. When she contacts Hiraga in order to tell him that Kagami had discovered their schemes, she asked if she should kill her, but Hiraga finds that to be too complicated and insists on hiding her instead, as their plan of attack would happen tomorrow morning anyway.

After Alice has hidden Kagami's body, she goes to her room where Shizuku is still awake reading a book. Alice and Shizuku share a drink together and Shizuku points out that Alice has finally opened up to someone, as she hadn't done so since arriving at Hagun Academy, much to Alice's own surprise. This brief conversation makes Alice realize that Shizuku has become her dear friend, and she wants to protect her.

Akatsuki Strikes
While on the bus back to the school, Alice confesses to everyone that she is an assassin for Akatsuki Academy with the goal of stopping their movements and allowing the Akatsuki members to defeat them easily. The students at first turned on Alice after this revelation, however, thanks to Shizuku pointing out the flaw in the very idea of an assassin pointing herself out before the plan is enacted, Ikki decided to trust her which allows the others to trust her as well.The students have arrived to a destroyed Hagun Academy, where they face off against Akatsuki Academy. Alice is able to instead bind the students of Akatsuki with her ability, Shadow Bind. However, she is soon stabbed multiple times in the back by Amane Shinomiya. It is then revealed that the real Akatsuki members were hiding as they knew of Alice's betrayal thanks to Amane's ability. Alice's unconscious body is then taken by Hiraga to Akatsuki Academy.

Alice regains consciousness and is confronted by her master Wallenstein. Alice tells Wallenstein that she betrayed him because she cared too much for Shizuku to allow her to be hurt. Wallenstein had become angered and begins to severely beat on Alice. Shizuku then arrives and battles Wallenstein. Although she is unable to match him in power, Shizuku is able to defeat Wallenstein using her new technique and save Alice's life.

After the Akatsuki scheme, it is revealed that Alice had dropped out of the Seven Stars Sword Art Festival believing herself be a detriment to the team if she stayed in as a representative of Hagun Academy.

National Powerhouses
Alice, Shizuku and Ikki decide to go out to eat and are invited by Yudai Moroboshi. They go to Yudai's family owned restaurant where they meet Kiriko Yakushi, one of the participants in the tournament. After lunch, Ikki separates himself from the group and Kiriko explains to Shizuku and Alice why Ikki will have trouble overcoming Yudai.

First Round Matches
The next day, Alice and Shizuku watch Ikki fighting and defeating last year's champion Yudai Morobashi. Next they watch Stella's victory against everyone else remaining in Block B. Alice along with Ikki, Shizuku and Kiriko then meet Amane Shinomiya and learn Amane's ability to manipulate events to suit his needs which causes Kiriko to be forced to withdraw in her fight against Amane due to her patients entering critical conditions.

Later Alice and Ikki are relaxing in the bathhouse, they meet Byakuya Jougasaki, who is the runner-up of the last year's tournament and Ikki's next opponent. Byakuya starts approaching Ikki and touching his body in amazement, with Alice about to join, but Yudai shows up stopping Byakuya. Alice and Ikki then leave, after Byakuya gives them cups of coffee.

Shopping Break
Alice, along with Ikki, Stella, Shizuku, and the Akatsuki member Sara Bloodlily go shopping in the city. Alice is asked by Ikki to find Sara some new clothes, as her current ones are impractical and could distract Ikki during their match. Alice then takes Sara with her and instructs her on things like cosmetics and clothes. As they enter Alice's Shadow Spot to try some makeup, Alice questions about Sara's connections to Rebellion, with Sara telling her that she is in debt to Rebellion, as one of its Numbers, the Grand Professor, cured her of her illness. Later, Alice shows Sara to the others, with her outfit being now even more revealing. Alice though explains that Sara couldn't wear any more clothing, as her body is too weak, although her outfit won't at least be as impractical as before.

Alice then leaves with Shizuku, who wants to prepare for her match against Amane. Shizuku tells Alice about her plan to attack Amane, who is Shizuku's opponent in the quarter-finals, before the match. Alice decides to help Shizuku because she is her friend.

Third Round Matches

After Amane survives Shizuku's attack, Alice tries to use her Shadow Bind on Amane, but the lights of the room, temporarily go out, negating Alice's shadow abilities. Amane then pierces Alice with multiple swords taking her out of the fight. Amane also defeats Shizuku. Both Alice and Shizuku survive and are later healed.

Preparation for the Final Match
Alice is seen battling Ikki in a mock battle, helping him train for the upcoming final match of the tournament.

The fight is however interrupted when other students, including Tohka and Yudai, arrive to help Ikki train.

The End of the Festival
