New S-Rank Agent: Promeia

Promeia is the featured character of the first Phase of Version 2.8. She is an Adjudicator of the Krampus Black Branch and an Ice Attribute Anomaly S-Rank Agent. While tracking the mysterious target “Ramiel,” she chooses to fight alongside the Proxy (the player).

Promeia Skill Features

Promeia’s core combat mechanic revolves around “Trial by Cold.” She consumes “Corrosive Chill” to accumulate Trial by Cold, which automatically triggers a powerful Abloom attribute anomaly once enough is gathered, dealing explosive Ice damage to enemies.

Her EX Special Attack activates the “Bound Absolution” state, allowing her to automatically trigger Perfect Dodges when attacked, significantly lowering the difficulty of operation. Additionally, when the team includes other Anomaly or Support Agents, Promeia provides an Abloom damage bonus to the entire squad, showing excellent synergy in multi-anomaly teams.

New S-Rank Agent: Starlight Billy

Starlight Billy is the limited character for the second Phase of Version 2.8. He is a fully upgraded S-Rank version of the fan-favorite A-Rank Agent Billy Kid—a reborn version after he spent six months’ salary on a complete modification.

Starlight Billy Skill Features

Starlight Billy is a Physical Attribute Stun S-Rank Agent equipped with a combat motorcycle and his signature “Starlight Knight Kick.” He can unleash overwhelming Physical burst damage. His Sheer Damage scales with his Max HP, and all Physical damage dealt is treated as Sheer Damage, allowing him to deliver incredible burst output when the Daze attribute anomaly triggers.

Some of his skills also feature HP regeneration, making him more stable in high-difficulty endurance battles, maintaining his output rhythm even under dense enemy attacks.
