A first-session guide built on the game's documented systems: claim the current code, learn the roll-place-upgrade loop, give your first squad real jobs, and start climbing toward the roll milestones that unlock the best codes.
If you only do four things tonight, do these in order.
Everything in this section is official or attributed, checked 2026-10-09.
The official description is the design doc: roll to unlock anime-style units, enter different maps and clear enemy waves, place your units and protect your base, upgrade your team, boost luck for rarer units, and defeat every map. Mera. — a verified Roblox group — created the game on March 26, 2026, servers hold up to 4 players, and it runs on desktop, mobile, tablet, and console.
Two documented facts make rolling strategic. First, Eurogamer's September 29, 2026 write-up notes units roll in automatically as you fight, so run length and roll income are linked. Second, most milestone codes gate redemption behind your lifetime roll count at the documented 10,000 / 25,000 / 50,000 / 100,000 thresholds — so the decision is rarely “should I roll” and usually “which map farms rolls fastest while I still clear it.”
The Roblox page title has renamed with each themed update: [BLEACH] in August, [Ghoul] on September 6, [Fire Force] on September 15, [World Relics] on September 20, [Gear 5] on September 27, an hourglass tag in early October, and [JJK+S2] as of October 6. Each era shipped its own code family — the update timeline keeps the whole history with sources.
Rarity odds, unit stats, per-map payouts, and trait prices are not in the official description and not in any dated tracker source this site checks. Where other sites quote exact numbers for those, they are guessing. This site's calculators take your measured values instead — that is a feature, not an apology.
Open the official Roblox page and read the description before joining. It carries the current official code (UPDATEKAISEN as of 2026-10-09), the feature list, and the group link. The bracket tag in the title ([JJK+S2] most recently) tells you which update era you are in, which explains the codes you are about to see.
In game: Codes button, right side, type exactly, Redeem. Start with UPDATEKAISEN (reported 1,000 Crystals + 1 Blessed Roll), then work down the codes page — newest era first. The popup is the ground truth; our reported rewards are dated tracker claims, and if one fails, the codes page already says which trackers disagree.
Documented code families lean on specific items: update codes pay Crystals plus a Blessed Roll; shutdown makeup codes pay premium rolls (up to 3 Divine Rolls); milestone packages pay boxes. The items-and-rewards wiki page explains each item type and its status. Potions (Refined Luck, Coin, Damage, Roll Speed) appeared in the August SORRYFORSHUTDOWN6 package — use luck potions before rolling sessions.
Cover bends and shared lanes so units attack longer; a mid unit on a long lane beats a strong unit on a short corner. Watch for the first leak: normal waves getting through means your clear unit needs upgrade depth, and a boss strolling in means you lack single-target pressure. Fix the visible failure, not the scariest-sounding stat.
Six roles, four of which matter early: wave clear, boss damage, one support, and a flex experiment. Enter your roster in the squad planner and it will warn about missing coverage — the two checks (waves cleared, boss killed) are exactly what every map run demands. Replace one slot at a time; keep the unit that fixes the last loss.
Before ending a session, check your lifetime roll count against the thresholds: 10,000 (GIANTKINGDOM-tier), 25,000 (SECRETAWAKENING-tier), 50,000 (BOSSRUSH-tier), 100,000 (LUFFOSUNGOD-tier). Crossing a threshold converts into free rewards from the codes page — the roll calculator helps you plan how many attempts a push is worth.
The official description says to join the group for rewards, updates, and more codes — the Mera. group is verified and the group join is the one official reward channel the description names. For update news, the game's Discord (community-corroborated invite on our links page) is where trackers say codes get announced.
The fastest documented income is code income — a single milestone code out-pays hours of early farming. Redeem first; the thirty-seconds you spend on the codes page change the whole session.
Crystals unlock traits, and trait prices are steep enough that the target matters. Put traits on the unit that already carries your runs — usually your wave-clear anchor — not on the rarest pull in the collection.
There is a similarly named game, “Anime Defense RNG” by a different creator, with its own wiki, units, and codes. Advice, unit names, and codes from that community do not transfer. Check the place ID or the links page when a guide looks foreign.
Redeem the current official code, then play your first runs with one goal: learn the roll-place-upgrade loop. The official Roblox description displays UPDATEKAISEN (checked October 9, 2026); trackers report it as 1,000 Crystals plus one Blessed Roll. Codes first, grinding second.
Launch the game from the official Roblox page, select the Codes button on the right side of the screen, type the code exactly into the field, and hit Redeem — then read the result popup, which shows the real reward. This flow is documented identically by Pro Game Guides (July 2026) and Eurogamer (September 2026).
Rolling is the core system: you unlock anime-style units by rolling, and luck boosts raise the chance of rarer ones. Eurogamer's September 29, 2026 description notes that you roll for new units as you fight. Your lifetime roll count also gates milestone codes at 10,000 / 25,000 / 50,000 / 100,000 rolls, so every roll does double duty.
Judge by job, not by rarity color: one dependable wave-clear unit, one sustained single-target unit for bosses, and at most one support. The developer publishes no stat table, so any named 'best unit' list without a source is noise — the squad planner on this site checks your roster by role instead.
On traits once you have a unit worth upgrading — Pro Game Guides documents Crystals as the trait-unlock currency. Exact prices are shown in your game, not in public sources, so check the trait screen before assuming a plan you read anywhere still fits.
