Shortly after, Stella was escorted to Hagun Academy by it's director, Kurono Shinguuji, happily welcoming Stella to Japan. Upon arriving at Hagun Academy, Stella is assigned a room and makes herself comfortable and changes after her long and busy morning, but as Stella is changing into her new school uniform, she is surpised to suddenly find an unexpected male visitor. Stella is shocked as the intruder has seen her naked, but before she can react the male student attempts to ease the situation, completely aware of the surroundings and situation and tries to even things between them, stripping and offering to see him naked. However, Stella is only further infuriated and embrassed and slaps the intruder and reports the situation to Kurono Shinguuji.
Once changing, an embarrassed Stella arrives at Kurono Shinguuji's office and once again meets her intruder, apologising for the events and introduces himself, Ikki Kurogane. Stella appears she is willing to out the situation to rest and offers not to make it an international incident and offers to give Ikki her mercy. However, Stella is revealed to still be greatly angered and orders Ikki's punishment for him to commit suicide.
Ikki Kurogane is the main protagonist of the series and Stella's main love interest. When Stella and Ikki first met, they didn't get along as Ikki had accidently walked in on Stella changing in their room, unaware of the news that they had become roommates. The situation further worsened as Ikki tried to make everything fair as he removed his own clothes. Stella was competely furious and embrassed of the situation and upon finally learning they are roommates, Stella tried to force Ikki to follow unreasonable rules. Ikki and Stella engaged in a mock battle with each other to settle the matter, while also deciding that the loser would become the winner's servant. Stella was also shown to be arrogant towards Ikki upon learning of his F-Rank as a blazer due to his lack of magical powers. However, much to Stella's surprise, through her battle with Ikki, Stella came to learn of Ikki's incredible power and skills. Stella also became happy and pleased that Ikki acknowledges her hard work through controlling her powers and knows she isn't simply talented, but refuses to show her feelings.
Stella ultimately lost the duel to Ikki and came to fully realize how powerful he really is. While she was recovering in the medical bay, Stella learned about Ikki's history at the school and his unfair treatment, but despite his struggles he never gives up. She started to respect and admire Ikki and quickly found herself developing strong romantic feelings for him. Stella quickly realized her feelings for Ikki as she was shown to be jealous of other girls around him and is constantly nervous or blushing whenever they are alone together. Since realizing her feelings, Stella attempts to be romantic with Ikki numerous times, but has great difficulty in expressing how she feels due to her extreme nervousness whenever they are together. Stella's uncertainty in regards to expressing her love for Ikki has occasionally lead to awkward or embrassing situations for the pair, but Stella never loses faith to show Ikki how she feels. Stella's love for Ikki grows stronger, including her admiration for him, leading it to become clear that Ikki is Stella's first real love.
Aside from being unable to properly admit or express her true feelings for him, Stella didn't confess her feelings due to her nervousness, but was also unsure if Ikki felt the same way about her. However, Stella also gained a rival for Ikki's attention and affections from his younger sister, Shizuku, who also harboured her own romantic feelings for him, despite their blood relation. Stella is jealous of Ikki and Shizuku's close relationship and is annoyed whenever Shizuku tries to come between them. Despite her struggles to express her feelings and Shizuku's interference, Stella still makes great effort to show to Ikki her true feelings for him.
Eventually, Stella and Ikki had confessed their feelings for each other during Ikki's first official match. During the match, Ikki nearly broke down due to mental stress and because of the crowd's discouragement towards him. However, Stella screamed at the crowd to stop harassing Ikki, encouraging him to contuine fighting, while also in some ways confessed to Ikki she loves him.
