- Anime Adventures Shibuya Portal drops from Shibuya Infinite mode in Update 20.
- Unlock requirement: Clear all Shibuya story stages (Act 6) to access Infinite mode.
- Drops are RNG-based: Portals are not guaranteed per run, similar to the Gilgamesh grind.
- Rewards: Sacred Treasure currency used to evolve new units, plus a chance at a secret portal.
- Solo-friendly: 15 waves, low-HP enemies, and a 2M HP boss make clear runs easy with Dark Mage.
What Is the Anime Adventures Shibuya Portal?
The Shibuya Portal is a dungeon-style portal item introduced in Update 20 of Anime Adventures, alongside the new Shibuya story map. Unlike the story stages themselves, the portal's unlock method is not explained in the update log, which left many players asking in the official Discord how to obtain it. The answer is simple once you know the loop: farm Shibuya Infinite mode, and portals drop randomly per wave.
Portals function as replayable dungeon entries. Clearing one awards Sacred Treasure (also referred to as Divine Treasure), the evolution currency for new Update 20 units, with a small chance at a secret portal drop that the community suspects leads to a raid-style encounter.
Video Highlights:
- Portals drop while grinding Shibuya Infinite mode, not from story stages
- Drops are RNG-based, like the earlier Gilgamesh portal grind
- Clearing a portal takes roughly 8 minutes and is easily soloed
- The Divine Treasure Portal comes bundled with Mega Mei (shiny included)
- Reward boosts increase the Sacred Treasure payout per run
There are multiple portal tiers in Update 20. The standard Shibuya Portal gives Sacred Treasure currency; the Divine Treasure Portal is obtained by acquiring Mega Mei (any version, shiny or normal) and comes bundled automatically.
How to Unlock Shibuya Portals: Step-by-Step
Follow this progression path to start farming portals efficiently. The entire unlock chain happens on the Shibuya map, the final story area currently in the game.
Clear the Shibuya Story
Complete all six acts of the new Shibuya story mode. This is the prerequisite for unlocking Infinite mode on the map.
Unlock Shibuya Infinite
Once every story act is cleared, Infinite mode becomes selectable. This endless wave mode is your portal farm.
Grind Infinite Waves
Run Infinite for as long as you can. Portals drop per wave over time, typically a couple per extended session, but nothing is guaranteed per run.
Stack Your Portals
Portals accumulate in your inventory. Stockpile them before attempting dungeon clears so you can chain runs back to back.
Clear the Portal Dungeon
Enter the portal, defend through 15 waves, and defeat the 2M HP armored boss to collect Sacred Treasure and a possible secret portal.
Do not expect a portal every run. The drop system mirrors the Gilgamesh grind, where some full Infinite sessions yield no portals at all. Consistency, not luck, builds your portal stock.
Portal Dungeon Walkthrough: Solo Strategy
The Shibuya Portal dungeon contains two separate enemy paths, which is the main challenge for solo players. Enemies have surprisingly low HP for a final-story dungeon, and the boss spawns randomized between both lanes.
Map Positioning
The key is finding the spot where both paths converge near the middle of the map. Placing your damage units there covers both lanes with a single stack, eliminating the need to split your defense.
| Position | Coverage | Difficulty | Notes |
|---|---|---|---|
| Center merge point | Both paths | Easy | Best solo spot, covers intertwined lanes |
| Left path only | Single lane | Risky | Boss may spawn on uncovered side |
| Right path only | Single lane | Risky | Same randomized boss spawn issue |
Recommended Loadout
| Role | Unit | Function |
|---|---|---|
| Main DPS | Dark Mage | Full AOE, ~600k damage per unit |
| Farmer | Megumi / Hekiro (new units) | Currency generation, 2 recommended |
| Support | Buffer units (e.g., Wender-type) | Buff Dark Mage output |
A full clear takes about 8 minutes with only Dark Mage placements, even without uniques or air-buff units. The 2M HP armored boss is the only real check, so AOE-heavy comps handle it comfortably.
Portal Rewards Compared
Update 20 introduced several portal sources and reward tiers. Here is how they stack up.
Shibuya Portal
- Farmed from Shibuya Infinite
- Drops Sacred Treasure currency
- Chance at secret portal (suspected Toji)
Divine Treasure Portal
- Bundled with Mega Mei (normal or shiny)
- Comes automatically on acquisition
- Suspected Mahoraga-related rewards
Secret Portal
- Rare chance from portal clears
- Community speculation: Toji encounter
- Highest-value target for grinders
| Portal | Source | Primary Reward | Additional Drop |
|---|---|---|---|
| Shibuya Portal | Infinite mode waves | Sacred Treasure | Secret portal chance |
| Divine Treasure Portal | Mega Mei acquisition | Premium rewards | Suspected Mahoraga |
| Secret Portal | Portal clears | Exclusive content | Unconfirmed target |
Sacred Treasure is the evolution currency required to evolve the new Update 20 units. More reward boosts equipped means more currency per portal clear, so activate every boost you have before starting a run.
Farming Checklist & Efficiency Tips
Use this checklist to maximize your portal farming sessions and avoid wasted runs.
Portal Farming Session Goals:
- Clear all six Shibuya story acts to unlock Infinite
- Complete a full Infinite run for portal drops
- Equip all reward boosts before portal clears
- Solo a portal clear from the center merge point
- Stack 5+ portals before chaining dungeon runs
Efficiency Notes
- Macro potential: Because your character respawns at the same location each time, an overnight macro placing Dark Mages on the central floor can automate clears, though this is advanced territory.
- Unit Manager: Update 20 added a unit manager quality-of-life feature, letting you locate and upgrade units without hunting for them on the map during Infinite runs.
- No carries needed: Enemy HP is low enough that solo clears are practical, so you do not need to rely on carrier services.
The wave-15 boss has armored properties. Full AOE comps like Dark Mage stacks still shred it, but single-target physical teams may clear noticeably slower.
