Girls’ Frontline 2: Exilium | Belka PV

Belka Overview

Belka is an Electric Vanguard specialized in hit and run play. She excels at flanking and eliminating high priority targets in a single strike. Her kit is fully functional at V0, making her one of the most efficient pulls for budget conscious Commanders.

• Seiyuu: Nozomi Yamamoto
• The Role: Electric Vanguard / High Speed Flanker.
• Stat Priorities: Attack Boost, Crit Rate, Crit Damage, Attack.
• Recommended Attachments: Phase Strike for overall utility.

Belka’s Skills & Keys

Understanding Belka’s (a) Keys

• Atmosphere Booster (Fixed Key): Essential for setup. If enemy units are within 5 tiles at the start of the turn, she gains Movement Up I for 2 turns.
• Raised Tail (Fixed Key): Damage boost. When using Crackling Core to attack an enemy target with Negative Charge, Belka’s attack increases by 10%.
• The Will to Fight for Favor (Common Key): Simple scaling. It increases Attack by 5% and boosts damage by 10% when expending mobility.

Expansion Key: Squirrel’s Awakening

This is her primary build anchor. It changes Sylvan Vault damage to Electric and scales Critical Damage based on Positive Charges on the field (up to 25%). It also makes sure that even short movements are calculated as if 10 movement points were expended, maximizing her damage floor.

Belka Rate-Up Banner

Belka’s debut banner runs alongside Groza and Colphne. As an Electric based Vanguard, she remains effective even at V0, making her a safe one copy pull for most teams.

Belka Vertebrae Breakpoints

• V0: Fully functional and strong right at base.
• V1: Minor quality of life upgrade.
• V3: A 33% damage increase. This is her highest scaling point for investment.
• V6: Provides a 20% damage bump over V5.

Disclaimer: It’s not recommended to pull for V3/6; one copy is sufficient for most players.

Verdict: Strong at V0, but her full potential is locked behind her expansion key. With Andoris on the same banner, most players can safely wait for a rerun unless Belka is a personal favorite.

Belka Team Recommendations

Belka thrives in squads that can keep the field charged.

The “Volt Vanguard” (Electric Rush)

• Main DPS: Belka
• Sub-DPS: Lenna (UMP9)
• Support: Leva (UMP45)
• Sustain: Andoris
• Strategy: This team utilizes the UMP sisters for out of turn damage while Belka handles the primary assassinations. Andoris provides the turrets to maintain Negative Charge stacks, allowing Belka to consistently hit her highest damage multipliers.

Sylvan Elf | Belka’s Signature Weapon

• Effect: Mobility used before attacking increases damage by up to 20%. If the target has Negative Charge, Electric damage increases by up to 25%.
• Trait: Gains a random buff if at full HP at the end of action.
• The Verdict: Skippable. While it fits her kit, Planeta or other high damage rifles provide better overall scaling for your resources.

Girls’ Frontline 2: Exilum | Andoris PV

Andoris Overview

Andoris is an Electric Bulwark who anchors the team through charge mechanics. Her auto turrets apply Negative Charge while her Ultimate applies Positive Charge, triggering technical combos with Leva and other Electric units.

• Seiyuu: Kiyono Yasuno
• The Role: Electric Bulwark / Charge Support.
• Stat Priorities: HP%, Defense%, HP, Defense.
• Recommended Attachments: Allay Support (Tank/Buffer) or Phase Strike (DPS).

Andoris’ Skills & Keys

Understanding Andoris’ Keys

• Careful Listening (Fixed Key): Momentum tool. She gains 3 points of Confectance Index at the start of battle.
• Shared Intelligence (Fixed Key): Team enabler. Applies Positive Charge to all allied Dolls for 3 turns at the start of battle.
• Inductive Field (Common Key): Increases Defense by 5% and scales damage based on the number of Electric debuffs on the field.

Expansion Key: Unwavering Vigil
This key turns Andoris into a defensive powerhouse. It restores CI if a turret deals no damage and increases turret attack by 50% against targets with Negative Charge. Most importantly, it allows Andoris to share 65% of incoming damage with units having Positive Charge, keeping your carries alive through heavy cycles.

Andoris Rate-Up Banner

Andoris specializes in high impact single target damage and remains effective at V0.

Andoris’ Vertebrae Breakpoints

• V0: Fully functional right away.
• V1: Significantly boosts Auto-Turret damage. Note that the new passive applies Negative Charge at the start of the turn, which can slightly reduce synergy with Leva’s Action Support.
• V6: Increases Electric damage dealt by allies by 30% if there are 3 Auto-Turrets on the field, massively boosting all Electric DPS units.

Verdict: Highly recommended at V0 if you are building Electric teams. V1 improves turret damage but can slightly disrupt UMP45 synergy. V6 is whale territory, providing huge Electric DPS bonuses if conditions are met.

Andoris Team Recommendations

Andoris is the definitive anchor for the 2026 Electric meta.

The “Static Shield” (Balanced Electric)

• Main DPS: Leva (UMP45)
• Sub-DPS: Belka
• Support: Jiangyu (Type 97)
• Sustain: Andoris
• Strategy: Andoris provides the Positive Charge baseline that Leva needs to scale. Jiangyu assists with stability break, while Belka cleans up high priority targets. Andoris’s turrets make sure Negative Charges are always present for the squad to exploit.

Aglaea | Andoris’s Signature Weapon

• Effect: Increases Electric damage for the team and recovers HP at the end of action.
• Trait: Damage taken is reduced by 2% for every Electric debuff the attacker is afflicted with. Maximum reduction of 6%.
• The Verdict: Skippable. Like Belka’s weapon, Planeta or Golden Melody are generally stronger choices for most roster builds.

Neural Helix & Boutique Updates

The Interstice of Reminiscence update also brings several veteran expansions and new looks.

• Mosin: Gains improved mobility and crit scaling.
• Ksenia: Receives utility buffs to her support actions.

Anniversary Boutique Outfits

• Enchanting Imp (Belka): The mischievous magical girl look is available at a limited time discount.
• Pinnacle of Virtue (Jiangyu): A high society formal look for the Electric support.
• Siberian Slide (Mosin): A skiing themed outfit obtainable as an event reward.

Closing Thoughts | Belka & Andoris Breakdown

This update focuses on building the foundation of your Electric core. Belka is a reliable one shot machine, while Andoris provides the technical support needed to make charge based rotations efficient.

Secure Andoris at V0 first to anchor your lineup, and consider Belka if you lack a dedicated Vanguard. Good luck with your procurement, Commander.
