Overview
Us. is a B-Class Plasma Arc with a simple always-on Basic Attack DMG bonus. The effect works without conditions or triggers, making it a clean early-game choice for any character who leans on Basic Attack chains before progressing to a 4-star or 5-star Arc.

Us. is a 3★ B-Class Plasma-type Arc in Neverness to Everness. It rolls a base 380 ATK at Level 80 with a 20% ATK% substat. The primary skill, Protocore, defines its role across rotations and team compositions.
Lore
"I am... you... are... you, are... it, is... me... no, I... am... us."
The flavor text sets the Arc's tone and gives designers a quick lens on how the Protocore passive is meant to feel in play.
Passive Effect
The Protocore passive provides the following effect at Refinement Rank 1: Increases the wearer's Basic Attack damage by 12%.
Refinement ranks raise these values without changing the trigger conditions. The table below lists the per-rank scaling.
Level | Basic Attack DMG |
|---|---|
L1 | +12% |
L2 | +13% |
L3 | +14% |
L4 | +15% |
L5 | +16% |
Ascension Materials
Reaching Level 80 with full access to the Protocore passive requires six ascension breakthroughs. Each phase raises the level cap and unlocks the next refinement condition. The costs are fixed per Arc and do not scale with refinement rank.
Phase | Level Cap | Gold | Materials |
|---|---|---|---|
Phase 1 | Lv.30 | 12,000 | |
Phase 2 | Lv.40 | 24,000 | |
Phase 3 | Lv.50 | 36,000 | |
Phase 4 | Lv.60 | 48,000 | |
Phase 5 | Lv.70 | 60,000 | |
Phase 6 | Lv.80 | 72,000 |
Compatible Characters
The listed compatible characters share the Arc's core synergy. Any character can equip any Arc regardless of element or skill fit, but these characters gain the full value of the Protocore passive thanks to their kits and scaling.
Character | Element | Rarity | Why It Fits |
|---|---|---|---|
5★ | S-Class Lakshana courier whose Blade Wings and motorcycle transforms chain Skill and Ultimate windows; a natural fit for the Protocore payoff. | ||
5★ | S-Class Anima main DPS whose follow-up attack scaling keeps stacks and buff timers fresh; a natural fit for the Protocore payoff. |
How to Obtain
Us. is acquired through the standard Arc acquisition methods in Neverness to Everness. B-Class Arcs can appear in the gacha system and its pity guarantees, in specific shop rotations, and in limited event reward tracks.
Method | Details |
|---|---|
Starter pulls | B-Class Arcs are the most common pull result and form the bulk of early-game Arc inventory. |
Beginner shops | B-Class Arcs are available through beginner currency shops and early-stage rewards. |
Event reward tracks | Most event tracks include a B-Class Arc at an early tier for players still building their roster. |
Strategy Tips
Confirm your chosen character's rotation lines up with the Protocore trigger before investing refinement materials. An Arc whose condition you cannot reliably fire is worth less than a B-Class Arc you activate every rotation.
At Refinement Rank 1 the values in the passive table are baseline. Early ranks give the biggest jumps; the last couple of ranks are smaller gains and usually not worth duplicating a 5★ Arc unless the character is a dedicated main DPS.
Pair Us. with Plasma-aligned Drive Blocks and KongMu Gear. Matching element on support gear stacks multiplicatively with the Arc's passive.
Keep the ascension materials in mind when planning farming routes. The final two phases jump from a 6x to a 12x requirement, which is often the real blocker for hitting Level 80.
Review the Compatible Characters table before equipping. Element mismatch still works, but the biggest multipliers assume the passive's trigger and your character's rotation are synchronized.
