Soren

Soren is one of the main characters of The Vampiress, and the Vampire Prince. He is also Tsubaki Tachibana's, or Lilith's, elder brother, which means his route contains incest.

Personality
Soren is a perceptive, serious, resourceful and very competitive person. His manner of speech is often hostile and dismissive of other people, but deep down he has a caring, big-brotherly disposition. His tendency of making trivial mistakes at the worst possible moment is a hereditary curse. Though he really is a lot nicer than he seems, he claims to always make his decisions based on cold, rational logic in the end.

Indeed, contrary to the typical reputation of demons, Soren is far from a sociopath and in fact displays strong moral standards multiple times; he is disgusted by the idea of Servants absorbing the mind and soul of humans just to increase their own mana, especially since the mana they get from their Masters should be more than sufficient, and considers such a thing too horrible to even think about.

He saw his father as a great Vampire who must be respected and loved, but failed to understand the negative aspect of his personality, the cold-heartedness that accompanied such an ideal.

All in all, Soreno spends just as much time quarrelling with Tsubaki as he did cooperating with her. Although he claimed to be not interested in anyone, the demonic love soul revealed that Soren has been attracted to Tsubaki after witnessing her stubborn attempts to finish a high jump that she had no chance of finishing when they were younger.

His hobbies include admiring jewels. Although wealthy from his family's magical patents, he feels somewhat ashamed of having to rely on the work of previous generations.

Magic and Abilities
Take Over (接収テイクオーバー Teiku Ōbā): Soren, alongside his siblings Tsubaki and Lycidas, is known for the accomplished use of Take Over, a form of Magic which, as the name implies, allows the user to take over the appearance and abilities of beings they really "know". Soren's form of Take Over Magic is called Beast Soul (獣王の魂ビーストソウル Bīsuto Sōru), which allows him to record and seal a monster's body part he has touched into his right arm, gaining the ability to subsequently transform his arm into that of the creature. Transformations seem to take place by tearing Soren's clothes off and covering his bare arm (or his entire body) with many flat, square-shaped plates, which subsequently disappear, revealing the summoned part. When he first revealed his power to Tsubaki, Soren displayed poor control of his transformations, suddenly changing his arm from the leg of a bear, to that of a giraffe; though also proving that even at a young age he had the strength to Take Over simple beasts. Transformation Magic (変身魔法 Henshin Mahō): Soren employs Transformation Magic, a Magic that allows him to change his appearance.
 * Partial Take Over: Initially, Soren, unlike his siblings, could only utilize Beast Arm (ビーストアーム Bīsuto Āmu), which exclusively transforms his right arm, something which made him uncomfortable. However, Soren's unique way of using Beast Soul seems to be somehow renowned.

Enhanced Durability: Soren possesses great constitution and durability.

Enhanced Endurance: Soren has been noted to possess a very large amount of stamina: while clad in his Lizardman form, he was shown able to undergo a long and exhausting barrage of unarmed blows.

Expert Hand-to-Hand Combatant: Despite favoring the use of his various weapons, Soren has proven himself to be a skilled hand-to-hand combatant. He is able to mix hand-to-hand combat with his swordsmanship while in the midst of battle.

Master Swordsmanship Specialist: Soren possesses great mastery in swordsmanship and his skills in swordsmanship are of the highest caliber. Soren has shown great skill in utilizing the reverse-grip of swordsmanship as well as the normal grip. He is even capable of employing his swords effectively using his feet, by wielding their hilts between his hallux and second toe. His sword slashes possess so much force behind them that they are able to slice through metal using only the air pressure from the swings.
