Echocalypse: Scarlet Covenant is YOOZOO's post-apocalyptic tactical-RPG gacha — recruit Kemono girls, build squads, fight through story chapters, PvP arenas and the Cataclysm world bosses. Top up Opal (the premium currency) here, delivered straight to your in-game UID.

About Echocalypse: Scarlet Covenant

Developed and published by YOOZOO Games (with Efun co-publishing in select regions), Echocalypse drops you into a ruined world where you play the Awakener — a commander who summons Kemono girls to fight back against the Empire and uncover what really destroyed the old world. Opal funds the character and weapon banners, the Monthly Card, the Battle Pass and the limited-time event packs.

• Gacha summoning — SSR / SR / R rarity Kemono girls across factions, with rate-up banners every event.
• Tactical squad combat — turn-based positioning, role synergies, formation buffs.
• PvP arena & Cataclysm bosses — ranked PvP plus weekly co-op boss raids.
• Story chapters — voice-acted main campaign with branching events and side stories.
• Cross-device — iOS, Android and PC client (Steam) on the same global account.

Why top up Opal here

• Instant delivery. Opal lands in your account in seconds — usually before your next pull.
• No password required. We only ask for your UID and Server. We never request your YOOZOO / Efun login, email or 2FA code.
• Better price than the in-game store. Discounted on every Opal tier we sell.
• Secure payment. Crypto, card and wallet checkout — encrypted end to end.
• 24/7 support. Real humans, not chatbots, if anything goes sideways.

How to top up

1. Pick the Opal pack you want from the list above.
2. Enter your in-game Echocalypse UID and select your Server.
3. Pay with crypto, card or your preferred wallet.
4. Opal is credited automatically — open Echocalypse and check your wallet.

How to find your Echocalypse UID

1. Open Echocalypse: Scarlet Covenant and load into the main lobby.
2. Tap your avatar in the top-left corner of the screen.
3. Your UID and the Server name are shown in the profile panel — copy the UID.
4. Type the UID and select the matching Server on this page before paying.

Important: copy the digits exactly and pick the correct Server. A wrong UID or Server sends Opal to the wrong account, and refunds for wrong-ID orders are not possible.

What you can buy with Opal

FAQ

How long does delivery take?

Direct Topup is usually under 60 seconds.

Do I need to share my password?

No. We never ask for your YOOZOO / Efun login, email or 2FA code. UID + Server is enough.

Which servers are supported?

The Global Echocalypse: Scarlet Covenant build — pick the matching Server when you place the order. Regional clients (Japan, Korea, Mainland China) use separate account systems and Opal bought here will not credit those builds.

What's the Monthly Card worth?

The Monthly Card pays out a chunk of Opal up front plus a daily Opal drip across 30 days — by far the most cost-effective Opal source for steady players.

Does the Battle Pass require Opal?

Yes — the premium track of the Battle Pass is unlocked with Opal and rewards extra character shards, Opal rebates and event-themed cosmetics on top of the free track.

What if I enter the wrong UID?

The Opal is credited to whichever account matches what you typed. Refunds are not possible once delivery succeeds, so double-check the UID and Server before paying.

Pick your Opal pack above and we'll have it on your account before your next 10-pull.
