Sylvia (シルビア, Shirubia) was a chimera and one of the eight generals of the Demon King, serving as the director of the Monster Enhancement Division. She served as the primary antagonist of the Konosuba Movie.
Sylvia had free-flowing bangs that were highlighted red and long, straight hair partially kept up in a bun at the top. Her eyes were purple and she had pointed ears similar to an elf, leading Kazuma to believe she might be some kind of demon.
At first glance, Sylvia appeared as a towering, voluptuous and beautiful woman. She was so attractive that Kazuma seriously considered defecting to the Demon King's Army to be with her. As a chimera, Sylvia possessed traits typically unique to both males and females, having big breasts and the figure of a woman, but also male genitalia.
Sylvia wore a crimson leather one-piece dress with low cut made from the skin of low-level devils, white-sleeved gloves, brown stockings, dark-red shoes, a gold necklace and a single blue earring on her right ear. She usually carried a rope around with her to use for the "Bind" skill.
After absorbing the mage killer, the lower part of Sylvia's body took on the shape of a metallic centipede with gem inscriptions. In the movie, after reviving and merging with Beldia and Hans, her lower body acquired a metallic semi-arachnid form around a blue semi liquid core and limbs. Sylvia's red dress is replaced with orange spikes that cover her breasts.
Sylvia was a smart and charismatic leader who seemed to genuinely care about the well-being of her subordinates, often shielding them from the magic of the Crimson Magic. She was shown to be very observant, such as when she deduced that Kazuma wasn't the famed magic swordsman Mitsurugi by noticing the low quality of his blade.
She was quite the seductive type as well, mainly due to the fact that she wanted to seduce Kazuma when he was taken hostage.
Sylvia also likes to taunt her enemies and make rude remarks about their strategies and their predicaments. When she's angry, her voice all of a sudden deepens and sounds more masculine.
Sylvia was a chimera, a creature which could assimilate living creatures and magical items into its physiology to grow stronger, as such a lot of her physiology was artificial. She served as a General in the Demon King's Army and was renowned as having the greatest magical resistance out of all the Generals.
Perhaps because of her magical resilience, Sylvia was sent with an army to annihilate the Crimson Magic Clan, a race of genetically modified humans who were highly proficient at magic.
Sylvia and her forces were no match for the Crimson Magic because, despite Sylvia‘s great magical resilience, her troops did not have such powers. Furthermore, although Sylvia was very resilient, she didn't have enough offensive power to deal with the Crimson Magic. Eventually Sylvia's objective shifted to obtaining and merging with a weapon sealed within the Village known as the "Mage Killer".
Eventually Sylvia fell for an adventurer by the name of Satou Kazuma, who unwittingly helped her absorb the "Mage Killer". With the "Mage Killer" absorbed, Sylvia transformed into a Lamia-like creature that was completely immune to any form of magical attack, and could spray fire from her mouth.
With this new transformation Sylvia was able to completely destroy the Crimson Magic Village, but was killed by Komekko, who used a special anti-Mage Killer weapon, before she could finish off its inhabitants.
Skills: Sylvia was able to use the Thief skill "Bind", summoning ropes that tie her enemy, leading Kazuma to speculate that she mainly employed Rogue skills.
Chimera anatomy: Sylvia is able to add organic and artificial parts to herself.
- Physical Resistance: Resistance against physical damage. Chimeras were well renowned for their incredible physical resistance.
- Magic Resistance: Prevents magic from taking effect. Chimeras were well renowned for their incredible magical resistance. Furthermore, as a chimera, Sylvia was only part demon, therefore priest magic, no matter how powerful, wasn't fatal to her.
- Mage Killer: After fusing with the "Mage Killer", Sylvia could breathe fire out of her mouth; although whether this was an ability provided by the "Mage Killer" or a spell she already knew is unknown. Her already impressive magic resistance was greatly increased when she merged with the "Mage Killer", to the point where even an Explosion spell might not have damaged her.
