Demon Slayer units in All Star Tower Defense X come from several different progression systems, including Trials, Portals, Tower floors, and Summons. Our team recommends checking each unit's acquisition method before spending resources, especially when planning which All Star Tower Defense X Items to save for evolution or ascension.
Not every unit follows the same upgrade path. Some require specific materials to evolve, others can only be ascended, and a few have no further upgrades available. This guide organizes the main Demon Slayer units by their acquisition and progression requirements so you can focus on the units you actually want to build.

Demon Slayer Units: Quick Overview
Use this table to identify where each unit comes from and which progression options are available.
| Unit | How to Get | Evolution or Ascension |
|---|---|---|
| Flaming Tiger (Rengoku) | Trial 4 or Trial Shop Star Scroll | Evolution |
| Frost Moon (Douma) | T6 Frost Moon Portal | Ascension only |
| Patternine (Akaza) | T6 Patternine Portal | Ascension only |
| Enraged Swordsman (Tanjiro) | Evolve Humble-Swordsman (Selection) | Evolution and ascension |
| Flower Trainer (Shinobu) | Frost Moon Portal Shop | Ascension |
| Gakukai (Kaigaku) | Clear Tower Floor 30 | Neither |
| Renitsu (Zenitsu) | Summon with a listed 1% chance | Neither |
The distinction between evolution and ascension matters when planning your farming sessions. Before collecting materials, confirm which system the target unit uses; otherwise, you may spend time gathering resources that do not contribute to its next upgrade.
How to Get and Evolve Flaming Tiger
Flaming Tiger, based on Kyojuro Rengoku, is a Primal unit that develops from single-target attacks into broader area damage. This makes him a useful option for players who want a ground unit capable of handling groups of enemies and contributing against bosses.
According to the supplied guide, there are two ways to obtain him:
- Trial 4: A listed 5% drop chance on Regular difficulty and 25% on Strategist difficulty.
- Trial Shop: Purchase the Flaming Tiger Star Scroll for 250 Flame Coins.
Flaming Tiger Evolution Materials
| Material | Quantity |
|---|---|
| Flame Cape | 5 |
| Slayer Earring | 5 |
| Dancer Mask | 5 |
| Ghost I (Red) | 7 |
| Ghost III (Rainbow) | 7 |

The main challenge is gathering the full material set, particularly the required Ghost fragments. Our team recommends checking the Trial Shop before each farming session and prioritizing materials you still need rather than repeatedly collecting items already in your inventory.
The listed drop rates and shop costs should be checked against the current game version before you commit to a long farming session.
How to Get Frost Moon and Patternine
Frost Moon and Patternine represent two different Demon Slayer characters, based on Douma and Akaza. Both use the T6 Portal system, and neither follows a traditional evolution path.
| Unit | Portal | Acquisition Method | Upgrade |
|---|---|---|---|
| Frost Moon | T6 Frost Moon Portal | Guaranteed when hosting; random chance when joining | Ascension |
| Patternine | T6 Patternine Portal | Guaranteed when hosting; random chance when joining | Ascension |
Portal tickets are listed as available through the Infinity Trial Shop. If you plan to farm either unit, check the ticket requirements and your available currency before committing to repeated runs.
The important distinction is the hosting requirement. Joining a portal run does not provide the same guaranteed acquisition described for hosting. If you specifically need Frost Moon or Patternine, confirm the current portal rules before choosing how to spend your tickets.

Because both units rely on ascension rather than evolution, keep their upgrade path separate from the material lists for Flaming Tiger and Enraged Swordsman.
Tanjiro, Shinobu, Kaigaku, and Zenitsu: Progression Requirements
These four units have different acquisition methods, so a single farming strategy will not work for all of them.
Enraged Swordsman: Evolution and Ascension
Enraged Swordsman is based on Tanjiro Kamado during the Mugen Train Arc. He can evolve from Humble-Swordsman (Selection) and can also be ascended.
Evolution materials
| Material | Quantity |
|---|---|
| Humble-Swordsman (Selection) | 3 |
| Slayer Earring | 4 |
| Demon Box | 5 |
| Ghost I (Green) | 5 |
| Ghost I (Orange) | 5 |
| Ghost II (Rainbow) | 3 |
Ascension requirements
| Material or Requirement | Quantity |
|---|---|
| Dancer Mask | 3 |
| Slayer Earring | 3 |
| Demon Box | 3 |
| Ghost I (Orange) | 5 |
| Ghost III (Rainbow) | 5 |
| Eliminations | 500 |
The supplied source associates Slayer Earrings, Demon Boxes, and Ghost fragments with Trials, raids, bosses, and Infinity Coin purchases. Check the current shop inventory to determine which materials you can obtain directly and which require additional farming.
Our recommendation is to plan evolution and ascension together. Since some resources overlap, tracking both material lists in advance can help you avoid unnecessary runs.
Flower Trainer: Shinobu's Ascension
Flower Trainer, based on Shinobu Kocho, is associated with poison damage and dodge mechanics. Her passive, Beautiful Poisonous Elegance, is described as combining poison damage with defensive utility.
The listed acquisition method is to purchase the Flower Trainer Star Scroll for 200 Infinity Coins from the Frost Moon Portal Shop.
Her ascension requirements are:
- 3 Insect Swords
- 5 Frost Moon's Hats
- 5 Ghost I (Green)
- 5 Ghost III (Rainbow)
- 500 Eliminations

If Flower Trainer is your target, focus on confirming the scroll's current shop location first, then track the ascension materials separately. This keeps the initial acquisition step from being confused with the later upgrade requirements.
Gakukai and Renitsu: Units Without Evolution
Gakukai, based on Kaigaku, is obtained by clearing Tower Floor 30. The supplied guide lists him as a five-star unit that cannot be evolved or ascended.
Renitsu, based on Zenitsu Agatsuma, is listed with a 1% summon chance and has no evolution path. His described combat trait allows him to attack while stunned, with damage amplification occurring over successive attacks.
For these two units, the main goal is obtaining them rather than farming evolution materials. If you are deciding where to spend your time, consider whether your current objective is Tower progression, Summons, or upgrading a unit you already own.
Summary: Which Units Should You Farm First?
Our team recommends choosing a target based on the progression system you can access most efficiently.
- For evolution: Start with Flaming Tiger or Enraged Swordsman if you can consistently collect their required materials.
- For ascension: Focus on Frost Moon, Patternine, or Flower Trainer, depending on which unit you already own and which materials you can obtain.
- For Tower progression: Work toward Floor 30 if Gakukai is your target.
- For summon-based collection: Renitsu requires patience because the listed chance is low.
Before spending currency, compare your current inventory with the complete material list. Players considering whether to buy All Star Tower Defense X Items should first identify the exact progression bottleneck and check the game's current rules, rather than assuming every required material can be obtained through the same method.
The most efficient approach is to work toward one clear goal at a time. Confirm the acquisition requirement, collect the necessary materials, and only then move on to the next unit.
