Lieselotte Sherlock

Lieselotte Sherlock is the twin sister of Selina who vanishes in the school library before Arata enrolled at the school. She is one of the Trinity Seven and is the last member Arata met. At first, she was opposed by Arata and the other members of the Trinity Seven. After being defeated when she attacked the school, Arata helped her out of the time dimension that she is trapped in.

Personality
Lieselotte personality is somewhat perverted, flirty and playful, especially towards Arata, who, by her admission, is the only man she's ever kissed outright. When she was battling the headmaster, she wasn't embarrassed to use her feminine charms to get an opening to defeat him. She is similarly crafty against the likes of Arata, using his desire to find Hijiri against him and stealing his power. She's quite openly attracted to Arata, which started pretty much immediately during their second encounter, and is evidently one of the most blatant of the girls around him in this respect, if not then she is the most.

After being saved by Arata, she shows much affection towards him even to the point that she said she liked him to Rouge before supporting him in battle against another magic king, Abyss Trinity.

She regularly calls herself the "evil" member of the trinity seven, and seems to be quite proud of that notion. Additionally, she is a headstrong and impatient individual, despite her crafty and calculating mind, in keeping with the concept of mages being the opposite of their respective Thema, in her case, Stagna "Stagnant".

She's quite affectionate towards her sister, though this does not apparently manage to prevent her from draining Selina's magical power to further her own ends.

Relationships
Arata Kasuga - As the last member of the Trinity Seven Arata meets, Lieselotte originally was missing before Arata transfered to Biblia Academy. She would suddenly reappear in front of him and the rest of the Trinity Seven, including her sister Selina, as an evil mage. Despite being an enemy, the two of them initially acted very friendly with each other, due to their similar perverted and laidback behavior, as well as their dislike of work. Although, Arata would disagree with her choice of stealing friends' magic. Nevertheless, Lieselotte took an immediately liking to him, finding him interesting and amusing. She also does not mind his perverted behavior, even playfully offering her own suggestive actions. However, she would end up stealing his magic, offering information on Hijiri if he joined her side to lower his guard. Later on, he would recover his magic by learning Akio's Mantra Enchanment and eventually defeat her. Regardless of her actions, he would still attempt to comfort, asking her to return with him to their friends. Unfortunately, her use of her FInal Techniqa trapped her in her own time dimesnion. Promising to save her, he would become determined to master her magic, Logos Arts, to bring her back. During Ish Kerioth's attack on Biblia Academy, she would be able to return thanks to her sister Selina lending her body. When prompted by Hijiri to choose a side, Arata's appearance would ultimately cause her to side with him and the Trinity Seven. Since then, the both of them have grown very close, strongly trusting in one another despite their past. During the Sky Library mission, Lieselotte would help prevent Arata from turning into Astral Trinity as well as teach him to master her magic so he could control Judecca. Believing that he didn't trust her, she was surprised when he allowed her to steal part of his magic, proclaiming that she was his friend no matter who she was and that he liked all sides of her. Hereafter, he would master the Logos Art with her help and bring her back to the real world. After that moment, Lieselotte has since become very grateful to Arata for saving her, caring deeply for him and getting jealous whenever he interacts with other girls. They are both willing to support and protect each other from danger. Out of all the Trinity Seven, they have kissed the most times.
