Summary
A silver haired girl is seen on a train, thinking about someone that she loved dearly, having to suffer great pain, because of their mother and father.

Stella and Ikki are then seen having just finished their daily 20 km run together. Ikki offers Stella a drink from his bottle, who is initially shocked at the offer as it would be an indirect kiss. Stella still takes it, as Ikki talks about his excitement about his sister coming to the school.

Yuuri Oreki, the homeroom teacher, introduces herself to all of the freshman and Ikki. Yuuri reminds the class that this year's participation for the Seven sword art festival, would be dependent on winning selection battles and nothing else and that they would be informed through their student ID. Yuuri then cheers on her students to participate in the selection battles, and then quickly throws up blood soon after falling unconscious.

Yuuri is then in the infirmary along with Stella and Ikki. Ikki explains to Stella that it was thanks to Yuuri that he was able to come to school in the first place. Yuuri also mentions how unfortunate last year was.

Ikki and Stella walk through the hall and Stella asks about what happened last year. Ikki explained he wasn't able to take classes last year and before he could properly explain further a girl named Kagami then appears to hug him, causing Stella to get jealous and walk away. Ikki chases after her as the girl with silver hair appears, and Ikki recognizing her as Shizuku, his sister. Shizuku then gives him a kiss to the mouth shocking everyone in the vicinity, including Ikki and Stella. Stella interrupts before Shizuku is able to kiss Ikki once again, causing Shizuku to become angered with her interruption. Stella explains that she interrupted because she was Ikki's servant and also stated that they had slept together in the same bed. Shizuku then decides to deploy her device, Yoshigure, to kill Stella and was confident that she would be able to do so as her element was water. Stella deploys her device in response and the two clash causing an explosion in the hall.

The two were punished with cleaning duty for their actions. After they were done cleaning Shizuku and Stella continued to argue causing Shizuku to accidentally bring up Ikki's past and how it felt as though he didn't exist to his family. Shizuku then ended the conversation leaving for her room. Shizuku is then welcomed back to her room by her roommate Nagi.

Stella then meets Ikki outside in front of the school where she questions him about if he was treated like he never existed by his family. Ikki decides to tell her the truth and depicted how his family had treated over the years. One day Ikki couldn't take it anymore and decided to run away during a very bad snowstorm. The moment he was about to collapse Ryouma, his grandfather, had appeared to him, encouraging him not to give up, as he carried him back to the home. Ikki continued to explain that his family had even pressured the school in making him fail, to make sure Ikki never becomes a knight.

While Ikki and Stella are talking Shizuku talks with her roommate and tells him about Ikki's situation and how she learned of it. Shizuku then tells him her resolve to give Ikki the fatherly, motherly, brotherly and sisterly love to him.

Ikki is then seen in the bath and Stella comes in wearing a pink bikini offering to wash his body. Ikki is reluctant, but Stella insists that a servant must server her master. While washing the front of Ikki's body, Ikki keeps on staring at Stella's bouncing breasts in a bikini top. While washing his back, Stella asks Ikki if he likes breasts, noticing he enjoyed it when Kagami was hugging him. Ikki admits to liking breasts and Stella decides to push hers breasts against Ikki's back much to Ikki's surprise. Feeling aroused, Ikki wanted to move, but Stella does not want him to. Her bikini top falls off to the floor which makes her look at her breasts. Her bare breasts were pressing against Ikki's back which causes her to become red. Ikki notices the bikini top and believes that Stella was naked (she was topless). Becoming angry, stella slapped Ikki.
