Become an Anime Billionaire Base Building Guide
Turn your plot into a maximum-income machine with smart slot management.
Your base is the only area where placed units generate passive income in Become an Anime Billionaire. Every empty slot is lost money, and every weak unit sitting in a slot blocks a stronger replacement. This guide teaches slot management from your first ten minutes through endgame rebirth cycles, with links to the Tier List, Merge Machine guide, and Offline Income guide.
Base zone overview
When you spawn into a server, you appear at your personal base plot. Key elements:
- Unit slots — Fixed positions where characters generate cash per minute.
- Cash pickups — Currency orbs that spawn near units during active play.
- Expansion options — Additional slots may unlock through progression, gems, or updates.
The base is separate from the shop roll area and merge machine side zone described in the Map guide. Learn Controls button layout so you can place and remove units quickly.
Golden rule: no empty slots
Empty slots earn zero income online or offline. Until you reach endgame optimization, any placed unit beats an empty slot:
- Day one: place every roll and code unit immediately.
- After codes: place Kiriko from
thisissecretbefore opening Friendship Lucky Blocks — see Kiriko guide. - Before logout: verify full occupancy for offline income.
Once all slots are full, shift focus from filling to replacing low earners.
Replacing weak units
Use this replacement workflow whenever you roll or fuse a new character:
- Open unit tooltip and note cash-per-minute.
- Identify your lowest-income placed unit.
- If the new unit beats that number, swap them.
- Store the removed unit as merge fodder if you have duplicates building toward five copies.
- Update mental tier list rank for your base roster.
Do not replace based on rarity color alone. A fused Epic can out-earn an unfused Legendary.
Early-game base setup (first hour)
Follow this sequence from the Getting Started guide:
- Redeem all active codes on the Codes page.
- Place Kiriko and any units from lucky blocks.
- Roll until slots are full or cash runs low.
- Walk the map center for totem crates — Map guide locations.
- Save duplicates off-base for future merge machine fusions.
At this stage, volume matters more than perfection. Income funds your first rebirth threshold.
Mid-game base optimization
After your first rebirth, base building shifts to quality:
| Priority | Action |
|---|---|
| 1 | Keep rebirth multipliers applied via point upgrades |
| 2 | Fuse five-copy stacks at merge machine |
| 3 | Replace D/F tier units with B tier or higher |
| 4 | Align roster with current tier list patch |
| 5 | Collect income totems during active sessions |
Open Friendship Lucky Blocks when slots need upgrades, not when income still climbs rapidly.
Late-game base layout
Veteran players maintain a ranked roster sheet mentally or on the Tools page:
- S-tier and A-tier units occupy every slot.
- Duplicates never sit in base unless no better unit exists.
- Pre-rebirth: place absolute best earners before reset, then rebuild quickly after.
- Post-fusion: immediate slot swap if fused unit jumps tiers.
Event units from the Events hub may temporarily displace B-tier slots during boosted income windows.
Base building and rebirth
Rebirth wipes placements and cash but not inventory. After each rebirth:
- Re-place code exclusives and fused units first.
- Fill remaining slots with highest available earners.
- Resume rolling toward next threshold.
Never rebirth with a half-empty base if you could have placed units — you lose rebirth point efficiency. Full checklist on the Rebirth guide.
Totems and base-wide bonuses
Totems from map crates apply base-wide bonuses rather than single-slot boosts:
- Income totems — Multiply all slot output; prioritize before long offline breaks.
- Luck totems — Help during roll sessions, less critical for static base layout.
- Speed totems — Shorten roll cooldowns during active farming.
Totems stack with rebirth multipliers. Collect them during the same session you optimize slot placement for compounding gains.
Base mistakes to avoid
- Hoarding strong units in inventory — They earn nothing until placed.
- Keeping F-tier units when replacements exist — Swap aggressively.
- Forgetting post-rebirth placement — Code units like Kiriko must be replanted.
- Over-investing in slot cosmetics — Gems go to merge machine first per Tools guide.
- Ignoring patch notes — Updates rebalance units; reorder slots after major patches.
Session routine for base maintenance
Experienced players run this at the start and end of every session:
Start: Redeem codes → compare tier list → roll or fuse → swap weak slots. End: Final slot audit → totem collection → logout for offline income.
Automation via Scripts can place units but carries ban risk; manual slot review keeps you familiar with meta shifts.

Frequently Asked Questions
Quick answers to the most common questions.
How many units can I place in my base?
Base capacity starts limited and can expand through progression. Fill every available slot as soon as you obtain units.
Should I keep low-tier units in my base?
Only if you have nothing better. Replace Common and Uncommon units as soon as Rare or higher units are available.
What happens to my base when I rebirth?
All placements are cleared and cash resets, but units remain in inventory. Re-place your best units immediately after rebirth.
Where should I place Kiriko?
Place Kiriko in any open slot immediately after redeeming thisissecret. She should stay placed until a clearly higher-income unit is available.
Do totems replace unit slots?
No. Totems provide passive bonuses to your entire base. They stack with income from placed units.
