Event Preparation Checklist
Before a new event starts:
- Save at least 200 stamina in mailbox/potions
- Keep 3-5 team slots open for event teams
- Have one well-built team of each damage type ready
- Maintain a stockpile of 500,000+ gold for shop purchases
- Review the event preview on official social media (posts 1-2 days before)
- Check plate weakness predictions to know which team to build
Stage-by-Stage Farming Strategy
Day 1-2: Clear Story Stages
Spend initial stamina on story stage first-clear rewards. Do not farm repeatable stages until all story stages are cleared — the first-clear rewards give more currency per stamina.
Difficulty priority: Expert > Hard > Normal
Day 3-13: Farm the Best Currency Stage
After clearing story, identify the most efficient repeatable stage:
| Stage | Stamina | Currency | 5★ Uniparts Drop | Efficiency |
|---|---|---|---|---|
| Normal | 10 | 15-20 | None | ★★★ |
| Hard | 15 | 25-35 | Rare | ★★★★ |
| Expert | 20 | 40-50 | Common | ★★★★★ |
Expert is almost always the best value unless you can’t clear it efficiently (more than 3 attempts needed).
Final Day: Spend All Currency
Clean out the event shop before maintenance begins. Set a timer for 1-2 hours before event end.
Event Shop Priority Ranking
| Priority | Item | Why |
|---|---|---|
| ★★★★★ | Premium Ticket ×10 (monthly limit) | Best value. 1 ticket ≈ 150 crystals |
| ★★★★★ | 5★ Uniparts Selection Box | Targeted 5★ set piece — invaluable |
| ★★★★★ | Exclusive Character / Weapon | Time-limited. May never return |
| ★★★★ | Awakening Crystal | Required for character awakenings |
| ★★★★ | Skill Refinement Core | Scarce outside events |
| ★★★★ | Crystals | Universal premium currency |
| ★★★ | Character XP Potion | Abundant from other sources |
| ★★★ | Gold | Farmable daily |
| ★★ | 3★ Uniparts | Too weak for endgame |
| ★ | Basic enhancement mats | Overflow from regular play |
Rule of thumb: First, buy everything that’s time-limited (characters, weapons, frames). Then, buy items that are scarce outside events (5★ Uniparts boxes, awakening crystals). Finally, spend leftovers on gold and XP.
Past Event Analysis
Festive Christmas (Akari Minase)
| Details | Info |
|---|---|
| Duration | December 24 - January 7 |
| New Character | Akari Minase (Festive Christmas) — 5★ ShotFire Attacker |
| New Weapon | AR-Xmas25, Ax-Xmas25, GS-Xmas25, HG-Xmas25 |
| Event Gimmick | +50% Fire DMG bonus, Burn DoT does 2x damage |
| Best Team | Fire DoT archetype |
Takeaway: This event established the Fire DoT archetype as a meta team. Akari Minase remains S+ tier.
Time of Radiant Splendor (Jura Igarashi)
| Details | Info |
|---|---|
| Duration | February 1 - February 15 |
| New Character | Jura Igarashi (Grit and Duty) — 5★ BluntFire Supporter |
| Event Gimmick | Afterburn deals bonus DoT ticks |
| Best Team | Fire DoT with double support |
Takeaway: Jura Igarashi doubled down on the Fire DoT archetype. Her Afterburn mechanic makes Fire teams viable against bosses that resist direct damage.
Interlude: An Ill Omen from the West (Soichiro Hoshina)
| Details | Info |
|---|---|
| Duration | April 15 - April 29 |
| New Character | Soichiro Hoshina (Keystone of Western Japan) — 5★ SlashShot Supporter |
| New Weapon | AR-6710, HM-Aimal, S-Iwanagahime |
| Event Gimmick | Action Order manipulation, bonus damage to Core Exposed |
| Best Team | Ultimate Burst with Soichiro support |
Takeaway: Soichiro Hoshina introduced action order manipulation — advancing allies on PLT destruction. This enabled new “speed clear” strategies for farming stages.
Upcoming Event Predictions
Based on the game’s release schedule and character release patterns:
| Predicted Event | Likely Timing | Expected Content |
|---|---|---|
| Summer Festival | Late June - July | New limited character, swimsuit cosmetics |
| Anime Season 2 Tie-In | TBD (aligned with anime) | Kaiju No. 9 or other major antagonists as playable |
| Anniversary | 6 months post-launch | Major celebration, free 5★ selector, double drop rates |
| Collaboration #2 | TBD | Potential crossover with another popular shonen series |
Event Team Templates
General Purpose Event Farmer
| Slot | Character | Alternative |
|---|---|---|
| DPS | Gen Narumi | Hikari Shinomiya |
| Sub-DPS | Soshiro Hoshina | Suited |
| Support | Chester Lochburn | Haruichi Izumo |
| Flex | Reno Ichikawa | Akari Minase |
Strategy: High AoE damage to clear waves quickly. Gen Narumi’s GS-Takamimusubi shreds through event stage mobs. Use auto-battle after manually confirming the stage gimmick.
Boss Challenge Specialist
| Slot | Character | Role |
|---|---|---|
| Main DPS | Kikoru Shinomiya | Ultimate burst for score |
| Debuffer | Wang Meixing | Shock Wire + ATK debuff |
| Support | Haruichi Izumo | Clarity stacks, SP battery |
| Tank/Healer | Akari Minase (4★) | Shield + sustain |
Strategy: Optimize for damage score. Stack CRIT DMG and Ultimate Gauge Charge Rate. Use Lizard-Type β on Kikoru for maximum burst during Core Exposed windows.
Event Currency Calculator
Use this formula to estimate your total event currency earnings:
Total = (Days_remaining × Daily_stamina × Currency_per_run / Stamina_per_run) + First_clear_bonus + Mission_rewardsExample: 14-day event, 240 daily stamina, Expert stage (50 currency / 20 stamina):
- Daily farming: 240 × 50 / 20 = 600 currency/day
- 14 days: 8,400 currency
- First clear bonus: ~500 currency
- Daily missions: ~200 currency
- Total: ~9,100 currency
Most important items in the shop cost approximately 5,000-6,000 currency, so you can clear all high-priority items without stamina refills.
Common Event Mistakes
- Saving event currency too late — Spend currency 2 days before event ends. Don’t wait for the final hour
- Skipping events for story progression — Events have limited-time rewards. Story mode isn’t going anywhere
- Ignoring daily event missions — They take 5 minutes and give significant bonus currency
- Not checking plate weaknesses — Event bosses often have unusual plate layouts. Check before building your team
- Over-farming beyond what you need — Once you’ve cleared the shop, stop. Save stamina for other content
- Missing login campaigns — The 1 minute it takes to log in is worth hundreds of crystals over time

Frequently Asked Questions
What types of events are in Kaiju No. 8 The Game?
Events fall into several categories: Story Events (narrative-driven with limited stages and shop), Boss Challenge Events (high-difficulty single-boss encounters), Collaboration Events (crossover with other series for exclusive characters), Login Campaigns (automatic daily rewards), and Server-wide Events (community milestones with global rewards).
How often do new events release?
Major events typically launch every 2-3 weeks alongside new character banners. Minor events (login campaigns, material drops) run in the off-weeks. A major story event usually lasts 14 days, while boss challenge events run for 7 days.
What should I prioritize in the event shop?
Premium currency (Gacha Tickets, Crystals), exclusive character/weapon if available, 5★ Uniparts selection boxes, awakening materials, and skill refinement cores. Gold and character XP are lower priority. Always clear out limited-quantity premium items first.
How do I get exclusive event characters?
Exclusive event characters are typically obtained through event gacha banners (using event-specific currency or premium currency) or as milestone rewards for accumulating a certain number of event points. Some events also offer event-exclusive 4★ characters as free rewards in the event shop.
What is the best stamina strategy during events?
Prioritize event stages over everything else during an active event. Event stages have 2x better drop rates for upgrade materials compared to normal stages and give event shop currency simultaneously. Use your daily stamina refills on event stages. Only farm normal stages if you're completely caught up on event rewards.
Can I still get event rewards after the event ends?
Most event-exclusive characters and weapons eventually return through rerun banners or are added to the standard pool after 6-12 months. Event shop items are lost forever when the event ends, so spend your event currency before the deadline. Login campaign rewards are permanently missable.
