Michishibo (Unbound Kokushibo) is one of the rarest and most powerful units in All Star Tower Defense. Getting your hands on this unit requires either incredible luck or serious dedication. The short answer: Michishibo drops from the Y Banner at a brutal 0.01% rate, or you can hit the 2,000-pull pity to guarantee it. Here's everything you need to know as of Update 6 in May 2026.
The primary way to obtain Michishibo is through the Y Banner. This is the only banner where Unbound units appear, so don't waste your gems pulling on the X Banner hoping for a miracle — it won't happen.
Michishibo sits at a 0.01% drop rate on the Y Banner. To put that in perspective, you'd need an average of 10,000 pulls just to have a statistically "expected" chance of seeing one drop. That's not a typo. The rate is genuinely that low.
Every single Y Banner pull costs gems, and the costs add up fast. Your best strategy is to stockpile gems over time and then spend them in large batches on the Y Banner. This doesn't improve your odds per pull, but it does let you make meaningful progress toward the pity counter (more on that below).
One important detail: every banner rotation can shift which Unbound units are featured. Make sure Michishibo is actually in the current Y Banner pool before you start spending. Check the banner details screen in-game to confirm.
If you're new to ASTD and still learning the basics, our beginner guide covers everything from gem farming to banner mechanics.
The Unbound Pity System is the safety net for players who aren't blessed by RNG. After 2,000 Y Banner summons without pulling any Unbound unit, the game guarantees you a Michishibo drop on your next pull.
There are a few critical things to understand about how this pity works.
Each banner has its own separate pity counter. If you pull 500 times on one Y Banner rotation and then a new rotation starts, your progress doesn't carry over. You need 2,000 pulls within the same banner cycle.
This Unbound pity is also completely separate from the standard 100-summon 5-star pity. The 100-pull pity guarantees a 5-star unit, not an Unbound. They track independently, so hitting your 100-pull pity won't reset or affect your Unbound counter.
At current gem costs, reaching 2,000 pulls requires a massive gem investment. Most free-to-play players won't hit this in a single banner rotation without weeks or months of saving. That said, it's the only guaranteed path to Michishibo if luck isn't on your side.
The math is simple but painful: 2,000 pulls is your ceiling. Every pull that doesn't yield an Unbound brings you one step closer. If you're committed to getting Michishibo, this is your fallback plan — and it's worth planning around.
Player trading exists in ASTD, and yes, you can trade for Michishibo. But don't expect it to be cheap. Michishibo commands one of the highest trade values in the entire game due to its 0.01% pull rate and dominant performance in endgame content.
Expect to offer multiple S-tier units or other Unbound units in exchange. The trade economy fluctuates, but as of July 2026, most Michishibo owners are either keeping theirs or asking for top-shelf offers.
Use the official ASTD Discord and trading communities to find potential trade partners. Always verify the trade before confirming — scams exist, and losing your best units for nothing is a brutal setback.
If someone offers you a Michishibo for a suspiciously low price, it's probably a scam. Know the current market value by browsing recent completed trades in community forums before you make any offers.
For players who already have a solid roster, trading can actually be the fastest route. If you've pulled duplicate high-value units from banners, those duplicates become currency. It's a viable shortcut if you've got the inventory to support it.
Before you invest thousands of gems chasing this unit, here's exactly what you're getting. Michishibo is a Purple element, Ground type unit with 3 max placements and 8 upgrade levels. Check our ASTD tier list to see where it ranks among all units.
| Stat | Base | Max (Level 8) |
|---|---|---|
| Damage | 420 | 17,498 (+4,374.50 Bleed) |
| Range | 10 | 33 |
| Attack Speed | 3 | 5 |
| DPS | 140 | 3,499.6 |
| Deploy Cost | 2,000 | |
| Total Upgrade Cost | 67,090 | |
| Max Placements | 3 | |
| Element / Type | Purple / Ground | |
Chained Moon (Upgrade 3): A Line AOE attack that hits multiple enemies in a straight path. This is your first major power spike and makes Michishibo effective against grouped waves.
Moonlit Misfortune (Upgrade 6): A Cone AOE ability that spreads damage across a wider area. This upgrade transforms Michishibo from a solid unit into a wave-clearing monster.
Transparent World (Upgrade 8): The signature ability. It reduces SPA by 10%, increases Range by 15%, and grants a 50% Dodge chance. That dodge alone makes Michishibo one of the most survivable DPS units in the game. Combined with the range and speed buffs, fully upgraded Michishibo is a different beast entirely.
Michishibo comes with two passives: Mastery of the Moon and Demon Hunger. These passives synergize with its aggressive playstyle, rewarding you for keeping it on the field and dealing consistent damage.
For traits, you want either All Star (+300% damage) or Bloodlust. All Star is the go-to choice for most players — a flat 300% damage boost on a unit that already hits 17,498 at max level is absurd. Bloodlust works well in extended fights where the sustain matters. If you can only pick one, go with All Star.

Pulling Michishibo is only half the battle. To fully ascend and unlock its potential, you'll need to gather specific materials. Here's the complete ascension requirement list.
| Material | Amount | Source |
|---|---|---|
| Jackzon Blood | 10 | Michishibo NPC in Infinite area |
| Ghost I (Purple) | 7 | Various game modes |
| Ghost III (Rainbow) | 7 | Advanced game modes |
| EXP IV | 5 | EXP farming stages |
| Gold Coins | 7,500 | General gameplay |
| Eliminations | 500 | Using Michishibo in combat |
The trickiest material on this list is Jackzon Blood. You can only get it from the Michishibo NPC located in the Infinite area. This means you need to be running Infinite mode regularly to stockpile this material.
You need 10 total, and the drop rate isn't generous. Plan on dedicating several Infinite runs specifically to farming this material. It's a grind, but it's a predictable one — unlike the banner RNG.
The 500 eliminations requirement means you need to actively use Michishibo in combat before you can ascend it. Deploy it in every game mode you play. Story missions, Infinite runs, challenge stages — anywhere it can get kills counts toward this total.
Don't leave Michishibo on the bench after pulling it. Start racking up eliminations immediately so this requirement doesn't bottleneck your ascension later.
Getting Michishibo is a long-term project for most players. Here are practical strategies to speed things up.
This sounds obvious, but discipline matters. Every gem you spend on the X Banner or other pulls is a gem that isn't going toward Michishibo. If this unit is your goal, commit to it fully and resist the temptation of other banners.
The ASTD dev team regularly releases codes that give free gems, gold, and other resources. These add up over time. Check our ASTD codes page — we update it whenever new codes drop.
Even small code rewards of 50-100 gems each contribute to your pity counter progress. Don't leave free gems on the table.
As mentioned earlier, knowing your exact pull count is essential. Some players keep a simple spreadsheet or note on their phone. Others use community-built tracking tools. Whatever method works for you, stick with it.
The worst outcome is losing track at 1,800 pulls and giving up, not realizing you were only 200 away from the guaranteed drop.
Focus on the game modes that give the most gems per time invested. Story missions, daily challenges, and event stages all offer gem rewards. Prioritize the highest-yield activities and run them consistently.

This might seem like strange advice in a "how to get" guide, but it's honest. Michishibo is incredible, but ASTD has other S-tier units that are much easier to obtain. If you're a newer player, building a strong team around more accessible units might serve you better in the short term.
You can clear most content in the game without Michishibo. It's a luxury pick — the best of the best — but it's not required. If the grind is burning you out, take a step back and focus on enjoying the game. The Y Banner will still be there when you're ready.

Michishibo drops exclusively from the Y Banner at a 0.01% rate. It cannot be obtained from the X Banner. Always confirm that Michishibo is in the current Y Banner rotation before spending your gems.
After 2,000 Y Banner summons without pulling an Unbound unit, the pity system guarantees a Michishibo drop. This Unbound pity is completely separate from the standard 100-summon 5-star pity counter. Each banner rotation has its own pity tracker.
Yes, player trading is available in ASTD. However, Michishibo commands an extremely high trade value due to its rarity and power. Expect to offer multiple S-tier or Unbound units in exchange. Use the official Discord and trading communities to find legitimate trade partners.
You need Jackzon Blood x10, Ghost I (Purple) x7, Ghost III (Rainbow) x7, EXP IV x5, 7,500 Gold Coins, and 500 Eliminations. Jackzon Blood is the hardest material to farm — it drops from the Michishibo NPC in the Infinite area.
Michishibo is one of the strongest ground units in the game with 17,498 max damage plus 4,374.50 Bleed. Its Transparent World ability at upgrade 8 gives 50% Dodge, -10% SPA, and +15% Range. It's a top-tier pick for endgame content. That said, you can clear most of the game without it, so only commit to the grind if you enjoy the process.
The two best traits are All Star (+300% damage) and Bloodlust. All Star is generally the preferred choice because a 300% damage multiplier on a unit with 17,498 base max damage is extremely strong. Bloodlust is a solid alternative for sustained fights where lifesteal matters more than raw burst.
