Sylus Character Guide: Profile, Personality, and Best Memory Cards

Sylus is 28 years old, 190 cm (6'2") tall, with short messy silver hair and bright red eyes, one of which glows brighter when he uses his powers. His birthday is April 18, placing him under Aries — confirmed consistently by both the game's native Chinese profile and the English wiki, with no discrepancy between sources.

He leads the organization Onychinus and carries the Energy Manipulation Evol. He was the fourth Love Interest added to the roster, released July 15, 2024, roughly six months after the game's original three.

Sylus first comes across as mysterious and intimidating, someone who stays calm and refined even in the middle of chaos, clearly interested in deals and control. Over time, softer sides surface — a soft spot for children and animals, a thrill-seeker's dislike of boredom, and a fondness for shiny things like gems and weaponry.

He is the fourth Love Interest and first appears in the Main Story chapter Long-Awaited Revelry, which opens shortly after his release.

Sylus has three 5★ Solar pairs (two are confirmed Myth):

• Captivating Flavor / Captivating Lesson — Pearl stellactrum, ATK-focused, released alongside his debut.
• Abyssal Blossom / Abyssal Mark — Emerald stellactrum, HP-focused.
• Crimson Rapture / Crimson Departure — Sapphire stellactrum, DEF-focused.

Community meta notes tag Sylus as a raw-damage-focused fighter, so guides generally point toward building his Pearl ATK pair first, then treating the Emerald and Sapphire pairs as secondary investments once resources allow — match Protocore color to whichever pair you build to fully trigger its bonus.
