Hollow is a Mythic-rarity unit in Anime Expeditions, built around the Burn status effect. Modeled on Gabimaru from Hell’s Paradise: Jigokuraku, he takes existing Burn stacks on an enemy and converts them into extra bursts of Flame damage. On his own that limits him, since he cannot apply Burn himself, but his evolved form Hollow (Blaze) is where the damage adds up.
Quick answer: Summon Hollow from the Beginner, Standard, or Mini banner at a 0.5% rate (guaranteed by the 400-summon Mythic pity), then evolve him into Hollow (Blaze) with 1x Elixir of Life, 20x Sprite (Red), 20x Sprite (Green), 1x Sprite (Rainbow), and 5,000 Gold.
How to summon Hollow
Hollow appears in the summon pool on three banners: Beginner, Standard, and Mini. As a Mythic unit he carries a 0.5% pull chance, so expect a lot of rolls before he shows up naturally. The reliable route is the pity system, which improves your odds heavily once you hit the 400-summon Mythic threshold.
You will know the pull worked when Hollow lands in your unit inventory as a Flame Element tower. From there he can be placed and leveled, but his real value only comes after evolution.
Evolution materials for Hollow (Blaze)
Evolving Hollow into Hollow (Blaze) requires a fixed set of items. Most come from the challenge rotation, while the Elixir of Life is tied to a dedicated trial stage.
| Material | How to obtain |
|---|---|
| 1x Elixir of Life | Complete the Elixir of Life Trial stage |
| 20x Sprite (Red) | Regular, Daily, and Weekly Challenges, plus crafting |
| 20x Sprite (Green) | Regular, Daily, and Weekly Challenges, plus crafting |
| 1x Sprite (Rainbow) | Daily and Weekly Challenges, plus crafting |
| 5,000 Gold | Clearing stages, completing quests, and more |
Once all five requirements are in your inventory, the evolution option unlocks and Hollow becomes Hollow (Blaze), keeping his Flame Element while gaining stronger passive output.
Hollow (Blaze) abilities
As Hollow (Blaze), the unit deals Physical damage through its attacks and runs entirely on passives. There is no active ability, which is the main thing holding him back as a pure damage dealer. His two passives, Radial Flames and Attack Flames, do the same thing under different conditions.
| Passive | Trigger | Effect |
|---|---|---|
| Radial Flames | An enemy with Burn stops ticking inside his range | Converts one Burn application into Austere Flames for 65% of current damage; does not stack |
| Attack Flames | He attacks an enemy already afflicted with Burn | Converts one Burn application into Austere Flames for 65% of current damage; does not stack |
Both passives feed off enemies that are already burning. Because Hollow (Blaze) has no way to apply Burn himself, he needs a partner that inflicts it. Flame Emperor is a strong choice to keep his passives firing, since a steady supply of Burn stacks is what turns those 65% conversions into consistent damage.
Best Traits for Hollow (Blaze)
Since Hollow (Blaze) is a straightforward damage unit, Unbound is the standout Trait. It raises damage by 350% and range by 10% while cutting his SPA by 5%, which stacks neatly with his flame conversions. Primordial and Draconic are solid alternatives if Unbound is out of reach.
Hollow (Blaze) rewards a specific setup rather than raw placement. Pair him with a reliable Burn source, slot Unbound if you can, and his repeated Austere Flames procs turn Burn-heavy waves into steady damage across the board.
