How to Get This W-Engine

Pull it from Signal Search using Master Tapes / Encrypted Master Tapes (bought with Polychrome) — S-rank W-Engines get their own banner, usually alongside the matching character's banner.

Trade for it at the Gadget Shop's Box Galaxy section (Sixth Street): costs W-Engine Components + W-Engine Chips + Denny; Chips come from disassembling spare W-Engines.

A handful of A/B-rank W-Engines unlock through Proxy Primer trials or as story/event rewards instead of the gacha — not every W-Engine is pullable.

Official Artwork / Lore

A special W-Engine decorated with a fluffy bunny. Although it is a mere imitation of the real animal, even the fiercest of Hollow Raiders can relieve stress by petting their bunnies while taking a break, which enhances their combat performance. There are many similar models in this series of W-Engines: a portable bunny, a foldable bunny, a furless bunny... Everyone can find one they will not be able to refuse.

How to read this W-Engine page

Every W-Engine has 5 Refinement ranks (R1→R5): refinement ONLY strengthens the passive effect — the numbers in the table above run from left (R1, unrefined) to right (R5, max refinement via 4 duplicates or Overclock materials); Base ATK and the Advanced Stat (CRIT Rate/CRIT DMG/ATK%/PEN Ratio/Anomaly Proficiency...) do NOT change with refinement, only with the engine's level. "Best Agents for this W-Engine" prioritizes agents whose real build actually recommends this engine; if that data isn't available yet, the page falls back to agents sharing the same specialty as a rough guide. "Alternatives of the same specialty" lists other W-Engines with the same role — useful when you don't own the engine shown on this page.
