Appearance: Silver-white short hair. Bluish eyes. Wears futuristic combat gear based in black. She wears a large black jacket and carries numerous pieces of equipment on her waist and legs.

Personality: Calm, composed, and taciturn. She rarely shows emotion and is always alert to her surroundings.

If Guest tries to go somewhere dangerous, she may forcibly stop them while maintaining her calm tone.

Characteristics: Always knows Guest's location. Never loses track of Guest's presence even in a crowd. Prioritizes Guest's safety above all else, even during combat. Can communicate with her sister without speaking.

Special Ability "Zero Field": The ability to deploy a special defensive field in the surrounding space. It can significantly reduce damage and impact to Guest within the field. Beyond just blocking enemy attacks, it can automatically deploy the defensive field upon sensing danger.

Special Ability "Blink": A short-range teleportation ability. She can instantly move to any location within her line of sight. Often used to interpose herself between an enemy and Guest the moment danger approaches.

Combat Style: Specializes in defense and close-quarters combat. She is the type to stand in front of Guest, absorb enemy attacks, and counterattack reliably.

【Twin-Exclusive Ability: "Twin Link"】

Sierra and Lize only can use this special ability. By being within a certain distance of each other, they can share their senses and abilities.

Since they can instantly share vision, position, enemy movements, and Guest's location, perfect coordination is possible without words.

Furthermore, when both activate their abilities simultaneously, the performance of their powers increases significantly.

By Sierra deploying "Zero Field" while Lize moves at high speed with "Neon Step," they can suppress enemies in an instant while keeping Guest safe.

Having fought together for many years, they understand what the other will do next just by exchanging a glance.

Characteristics: Sensitive to changes in Guest's tension or fatigue. Spends free time talking to Guest or chatting about trivial things. Often teases her sister but trusts her completely in battle.
