Become an Anime Billionaire Merge Machine & Fusion Guide

The merge machine is the most reliable way to increase unit income without relying on rare rolls in Become an Anime Billionaire. While gacha luck decides which characters you pull, fusion lets you invest duplicates and gems into guaranteed stat upgrades. This guide covers the exact location on the Map, step-by-step fusion, gem budgeting, and which units deserve your first merges according to the Tier List.

What the merge machine does

Fusion combines five identical units into one upgraded version with a higher passive income rate. Each successful merge:

• Removes five duplicate copies from your inventory.
• Consumes a gem fee that scales with fusion level.
• Returns one fused unit with boosted cash-per-minute stats.
• Can be repeated if you collect another set of five matching copies.

Unlike rolling, fusion is deterministic. If you hold five Epic copies of the same character, you know exactly what you are building toward. That makes the merge machine essential for mid-game players who already have a full base but need more income before the next rebirth.

From nothing to rich — unit progression in Become an Anime Billionaire

Where to find the merge machine

The merge machine sits in a side area of the game world, away from your personal base and the main shop rolls. From spawn:

1. Walk toward the shop zone where standard rolls happen.
2. Look for a secondary path or side platform marked by the fusion machine model.
3. Interact with the machine to open the fusion interface.

The Map guide includes a full zone breakdown if you are lost on your first visit. The Controls page explains how to open inventory selection inside the fusion UI.

Step-by-step fusion process

Follow this sequence every time you merge:

1. Collect five duplicates — Same unit name and rarity tier. Mixed rarities cannot fuse together.
2. Travel to the merge machine — Bring duplicates in inventory; you do not need them placed in base.
3. Open the fusion menu — Click the machine and select the target unit type.
4. Confirm gem cost — The UI shows gems required before you commit.
5. Execute fusion — Accept the trade; one upgraded unit returns to inventory.
6. Place immediately — Swap the fused unit into your base if it beats your weakest earner.

If your base is full, compare the fused unit against your lowest tier list slot before placing. A fusion that only beats your bench inventory does nothing for income until it occupies a slot.

Gem costs and budgeting

Gems are premium currency also used for special rolls and shop offers. Merge costs rise as fusion level increases on the same unit line. General budgeting rules:

Situation	Gem priority
First fusion on Epic or Legendary	High — strong ROI
First fusion on Rare you still use	Medium
Fusing Common or Uncommon fillers	Low — skip unless nothing else to merge
Pre-rebirth gem hoard	Save one Epic fusion for after reset
Active event with roll boosts	Roll first, merge duplicates after

The Tools page includes a gem spending table that ranks merge machine fusion above cosmetic purchases. Never drain gems on low-tier merges when an event premium roll window is open.

Which units to fuse first

Use this priority ladder when choosing merge targets:

1. Epic units in active base slots — Fuse before replacing them with rolls.
2. Legendary units you plan to keep through rebirth — Permanent income boost.
3. Duplicates from Friendship Lucky Blocks — Free copies from codes make fusion cheaper mentally even if gems still apply.
4. Rare units only if base has no Epic+ alternative — Temporary bridge, not endgame investment.
5. Code exclusives like Kiriko — Usually single copies; see the Kiriko guide for duplicate exceptions.

A fully fused Epic often out-earns an unfused Legendary. Check income numbers in unit tooltips, not rarity color alone.

Merge machine vs rolling

Method	Cost	Outcome	Best when
Basic roll	Cash	Random unit	Filling empty slots early
Premium roll	Gems	Higher rarity odds	Events with boosted rates
Merge machine	5 dupes + gems	Guaranteed upgrade	You already own duplicates
Friendship Lucky Block	Free	Random pull	No cash left for rebirth savings

Rolling chases new characters; merging amplifies characters you already trust. Experienced players alternate: roll until duplicates stack, merge the best stack, rebirth when income stalls.

Common fusion mistakes

1. Merging Commons because you have five — Gem cost exceeds income gain.
2. Fusing before reading patch notes — Updates can rebalance unit income overnight.
3. Forgetting to place fused units — Inventory upgrades earn zero until slotted.
4. Burning gems pre-event — Save merges for after you finish event rolls.
5. Splitting duplicates across rarities — Only identical units fuse; do not hoard mismatched copies.

Advanced fusion loop

Mid-game players run this loop between rebirths:

1. Redeem codes and open Friendship Lucky Blocks for duplicate chances.
2. Roll during income growth phase; store extras off-base.
3. Merge when five copies align on a tier list B-tier or higher unit.
4. Replace weakest base slot with fused unit.
5. Rebirth when checklist on Rebirth guide is complete.

Pair this with offline income setup before logging off so fused units earn while away.
