Two patches define where Anime Astral Simulator sits right now. Update 12 opened World 16, Tokyo Ward, along with a 100-wave raid and the RC Cell economy that feeds Kagune upgrades. Update 15.5 stacked a skill tree, an artifact craft, a new gacha, and a 50-level Battlepass on top of it. Seven codes shipped across the two patches, and they are the cheapest way to fund your first round of summons.
Quick answer: Redeem MINI15.5, HOLYGRAIL, BANKAI and PRANATREE from Update 15.5, then UPDATE12, KAGUNES and FRIENDSLEADERBOARD for 600 F2P Tickets, 15 potions and two Tower Cooldown Resets.
Update 15.5 and Update 12 codes list
Update 15.5 came with four codes, all redeemable in the same menu:
MINI15.5HOLYGRAILBANKAIPRANATREE
The three Update 12 codes have itemized payouts, and two of them clear your Tower cooldown. Spend those resets before you queue into anything else, since they sit in your inventory doing nothing otherwise.
| Code | Rewards |
|---|---|
UPDATE12 | 200 F2P Tickets, one each of Damage II, Power II, XP II, Yen II and Luck II Potion, 1 Tower Cooldown Reset |
KAGUNES | 200 F2P Tickets, one each of Damage II, Power II, XP II, Yen II and Luck II Potion, 1 Tower Cooldown Reset |
FRIENDSLEADERBOARD | 200 F2P Tickets, one each of Damage II, Power II, XP II, Yen II and Luck II Potion |
Each account can redeem a given code only one time. No response means the code was entered incorrectly or that account has already redeemed it.
How to redeem Anime Astral Simulator codes
Update 15.5 systems and where to find them
Update 15.5 is a mini patch, but most of what it adds sits in Fuyuki City and Hueco World rather than in a brand-new zone. Nothing here requires a new world unlock, so a returning account can touch all of it the same session.
Prana Tree in Fuyuki City (World 19)
The Prana Tree lives in Fuyuki City, World 19. Opening it brings up the Prana Awakening interface, a hexagonal grid of nodes you unlock by spending Prana Coins. Early nodes are cheap, and each one you buy opens the neighbouring nodes on the grid, so the tree expands outward rather than down a fixed line.
Craft Holy Grail artifact and the Holy Grail War raid
The artifact craft is also in Fuyuki City. The Craft Holy Grail menu lists four requirements, Holy Grail fragments I, II, III and IV, and the craft only completes once you hold all of them.
You create the Holy Grail War raid from the Teleport menu, and starting one costs 1x Command Seal Key. Before you begin farming, open Settings inside the raid and configure Auto Retry along with Auto Leave at a chosen wave. That turns repeated runs into a loop you do not have to restart by hand. Drop I, II and III potions from the Boosts and Inventory menus raise loot rates while you grind, and they stack with the raid’s normal drops.
The 50-level Battlepass and its accessory rewards
Update 15.5 introduced a 50-level Battlepass with free and premium reward tracks, paying out pets and accessories. The premium tier is bought with tickets, and once you own it the Claim All button collects everything you have already earned in one press. Accessory inventory capacity also went up, topping out at 575 items, which matters because the pass hands out a lot of them.
The track awards two named accessories. Inventory crafting can roll accessory curses onto the Eugeo Weapon, while Kirito Protection is a Mythical item with its stats shown on the inventory card. Promotions use a separate tier ladder during this progression; Promotion 44 requires player level 80 plus a victory over Goetia.
Bankai gacha in Hueco World
The Bankai gacha sits in Hueco World. The roll interface prints its own percentages and the multiplier each result carries, so read those before committing tickets from your code haul.
Progression caps and the Fritz Family gacha drop
Every world progression gained 50 levels, moving caps from 200 to 250. The progression menus support auto-rolling, so you can push each world up to its new ceiling without clicking through every level. Separately, Fritz joined the Family gacha in Titan Wall at a drop rate of 0.000173%, which puts it firmly in long-shot territory. The patch also logged 123 new achievements alongside balance changes and bug fixes.
Tokyo Ward (World 16) and the Owl Suppression raid
Update 12 centers on Tokyo Ward, a Tokyo Ghoul-inspired zone accessed from the world teleporter just like the other maps. The hub places the pet gacha, crafting bench and raid entrance together, letting you complete the entire loop there.
| Addition | Details |
|---|---|
| New world | World 16 – Tokyo Ward |
| New raid | Owl Suppression, 100 waves |
| New gachas | CCG Extermination and Kagunes |
| New units | 10 pets, 7 avatars |
| Other content | New questlines and a world boss |
| Level cap | Raised to 275 |
| Quality of life | Friend Leaderboard tab |
Owl Suppression raid waves and RC Cells
Owl Suppression contains 100 waves, and every fifth wave brings a boss, creating difficulty jumps in blocks rather than a steady curve. Its entry panel shows the access requirement and the payout, so inspect it before queuing. The target resource is RC Cells, the sole currency used for Kagune upgrades.
Kagune gacha and RC Cell upgrades
Kagunes roll from their own pool, separate from pets. Once you own one, RC Cells level it, and each level raises whichever stat that Kagune carries. The boostable stats are Power, Damage, Yen, XP, Drop, Luck and Crit.
Each level provides only a modest increase. Scarlet Wing, which is a Legendary Kagune, has x2 Power initially and becomes x2.12 Power after a single upgrade. Use RC Cells as a gradual permanent investment, prioritizing a Kagune with the stat suited to your current farming goal. CCG Extermination is the other new pool, and its summon screen shows a separate set of drop rates.
Ghoul Progression and crafting Kaneki
Tokyo Ward has a distinct advancement path called Ghoul Progression, supplied by materials enemies in the zone drop. Those materials are used in the crafting menu for new units, where every recipe’s requirements are shown beforehand. Kaneki requires Ghoul Shards, and Craft remains unavailable until you have the necessary amount.
Accessory slots, relics and pet loadouts
The Accessory tab in the inventory keeps separate Head, Torso, Back, Shoulder and Waist slots. Relics carried over from earlier worlds can still be levelled there, which is useful filler while you build up Tokyo Ward materials.
Avoid sorting pets by hand. Search Pet, Filters, Equip Best and Unequip All are available in the Pets menu, and Equip Best rebuilds your equipped lineup whenever summoning changes the roster. Nishiki Nishio is one of the ten additions to the Tokyo Ward pool, while duplicate pets accumulate in the inventory normally.
Shop costs for Update 12 purchases
| Purchase | Cost |
|---|---|
| 2x Exp Gain gamepass | 2,990 F2P Tickets |
| Premium Battlepass | 4,449 F2P + P2W Tickets |
| Waifu Bundle 5 | 5,999 F2P Tickets |
You can pay for both the 2x EXP gamepass and Waifu Bundle 5 with F2P Tickets, allowing code rewards to go directly toward those purchases. P2W Tickets are additionally required only by the Premium Battlepass. Waifu Bundle 5 includes Mitsuri, a Limited pet with a base x28M power multiplier that reaches x32.2M after an upgrade.
Level cap and the Friend Leaderboard tab
The current player level ceiling is 275, giving the 2x EXP gamepass much more progression space than before. A Friend Leaderboard tab was also added: it limits the ranking view to your Roblox friends rather than the entire server, which makes it useful even if the global board is out of reach.
When returning after time away, use this order: redeem codes, apply the Tower Cooldown Resets, then spend tickets on the gacha tied to your target. The remaining work, including Prana Coin nodes and the RC Cell grind, follows from that initial session.
