S'yne's Sister

S'yne's sister is a powerful member of the organization behind the waves and is often seen with the vanguards of the waves testing their new technology.

Appearance
S'yne's sister is a mature woman with striking cream-coloured hair. She is relatively tall and quite beautiful. She wears highly revealing clothing with large buttons placed in random places. Her clothing design is very similar to S'yne's although it also uses a fur material. She also has the same cool, collected demeanour as S'yne.

Personality
Beneath her cool demeanour, S'yne's sister hide a sadistic side. She loves to torment others, including her own sister, for her own enjoyment. She is completely confident in her abilities and has the skills to back up that confidence. However, more than anything, she loves a challenge. She often gives hints to Naofumi and the heroes how to defeat her team and has many times decided to walk away instead of defeating the heroes - which she could have easily done. She has even gone to the point of letting her own allies lose for the opportunity to let the heroes to grow.

Interestingly, S'yne's sister ostensibly arrogant attitude is a facade. She does not truly have the same intent as women like Malty but her true intent is unknown.

Raino think that she is good person if compare her with other vanguards of the waves women, but Raino hate her name,

Abilities
S'yne's sister is a dangerous enemy for the heroes. Unlike the vanguards of the waves she is a competent leader and is capable of seeing ahead in the battle. Besides her tactical mind and intellect, she is also an incredible fighter. After the heroes' fight with Miyaji, just a single flip of the chain sent all of the heroes flying. Finally, although she tends not to use it, she is also talented in seducing and manipulating people.

Technology

 * Holy Weapon Suppression: S'yne's sister tinkered with one of the dragon hourglasses of Glass' World. As a result, they were able to suppress the Holy Weapons of Raphtalia's World in Glass' World such as the Legendary Shield or Legendary Bow.

She states that she is actually using an innate defence system of the Dragon Hourglass and Legendary Weapon system.
 * Artificial Behemoth: During the second fight with the heroes. S'yne's sister tested out the Artificial Behemoth. This beast was created using a legendary weapons and its power-ups. It is activated from a round ball when thrown. This beast looks like it has the body of a lion and the cow-like head. It has a steel, visor-like, bar across its eyes with two red lights for eyes. It also wears a metallic armor around the chest. This beast was so powerful that none of the Heroes could take it on, except for Kizuna who specializes in fighting monsters. As of the first test with the heroes, the Artificial Behemoth cannot use skills or magic.

Background
S'yne and S'yne's sister were both Vassal Heroes from the same world. However, despite being a Vassal Hero, she joined the self-proclaimed leader who was taking advantage of the waves. Together, they destroyed her own world. From then on, she joined her leader to control the Holy Heroes the leader's world. When most of the heroes were killed and the last one was caught by a terrorist group, Malty and her group joined forces so the last hero wouldn't be killed and the leader's world would remain intact. Earning the leader's respect, Malty and her group were put under S'yne's sister's care.

Volume 17
During the heroes' fight against Miyaji to save Kizuna, S'yne's sister had appeared. She didn't help out significantly during the fight but decided to "have fun" with her sister instead. During the battle, she explains to Naofumi and the heroes how the technology to suppress their Holy Weapons had worked and how to liberate Vassal Weapons which have been suppressed. After Miyaji, Mald and Malty had been defeated, S'yne's sister picked up the survivors and started to leave. At the resistance of the heroes, she knocked them all down in a single blow. She also reveals that the vanguards of the waves that they have been fighting against are only "low-level thugs." She then leaves without a trace.

Volume 18
S'yne's sister later appears among a crowd of volunteers for L'Arc's forces. She comes with Lesty and three vanguards of the waves under her control. After some conversation, her forces and the heroes fight. During the fight, she also tested out the Artificial Behemoth against the heroes while she stood back and watched. Upon the Demon Dragon's request, most of the heroes worked together with her and they were able to kill Lesty and the main vanguard of the wave - "Enemy of the Week." S'yne's sister teleported away before the attack was landed. Now that the heroes had a single enemy remaining - the Artificial Behemoth - they were able to work together to defeat it. With its defeat, S'yne's sister appeared to take the corrupted legendary weapon inside. The heroes try to take her on again but are quickly defeated. She then uses a movement skill to leave.
