BLEACH Mirrors High: How to Pre-Download and Claim Day 1 Rewards

To claim every confirmed Day 1 reward in BLEACH Mirrors High, download the base client before server launch, launch the app immediately to install the secondary asset update, and clear the prologue once servers go live. Finishing the opening tutorial unlocks the in-game mailbox, which holds your pre-registration summon tickets, launch currency packs, and celebration bonuses.

Pre-Downloading and Patching Game Assets

Installing the initial store package from iOS or Android does not fully prepare your device for launch. To avoid download queues and server bandwidth limits when the game officially opens, complete the full setup beforehand:

Install the Store Package: Download the application file from your mobile app store during the pre-download availability window.
Launch the App Immediately: Open the game client to trigger the in-app patch. This step unpacks game data and downloads essential secondary assets, including character models, cutscenes, and stage files.
Verify Local Storage: Ensure your device has enough free storage beyond the base installer size to accommodate unpacked cache files.
Maintain a Stable Connection: Keep your device connected to Wi-Fi until the progress bar finishes to avoid file corruption that could force a complete reinstall.

Milestone and pre-registration items do not automatically credit to your inventory upon account creation. You must progress through the mandatory tutorial and finish the prologue chapter before the main menu mailbox unlocks.

Reward Category	Delivery Location	Access Requirement	Primary Purpose
Pre-Registration Summons	In-Game Mailbox	Clear prologue and tutorial	Pulling on standard or starter banners
Launch Currency Packs	In-Game Mailbox	Clear prologue and tutorial	Hoarding for limited-rate banners or stamina
Day 1 Celebration Gift	In-Game Mailbox	Create account on Day 1	Starter roster upgrade consumables
Daily Login Stamp	Event Calendar Screen	View event tab each daily reset	Progressing toward multi-day check-in milestones

Mailbox items typically carry expiration limits lasting 14 to 30 days, though specific launch bonuses can expire sooner. Check each message directly upon unlocking the mailbox to confirm its remaining duration.

Unlike lump-sum mailbox gifts, launch celebration login campaigns require active check-ins across multiple days. The initial stamp registers as soon as you access the event tab on Day 1. Log in well ahead of the standardized daily reset to secure your first stamp immediately. Missing the launch-day window delays your progress toward late-week login milestones, such as guaranteed high-tier tickets.

Using Day 1 Rewards for Rerolling

The pre-registration currency and summon tickets granted upon tutorial completion serve as the starting resource pool if you choose to reroll for high-tier starter units:

Start on a Guest Account: Do not link an email or social profile on your initial boot. Play through the prologue on a guest profile to verify your starting summons first.
Confirm Reward Delivery: Open the mailbox after the tutorial to ensure the full pre-registration reward batch has delivered before spending your tickets.
Hold Promotion Codes and Account Binding: Avoid redeeming single-use account codes or binding external credentials until you pull a roster you intend to keep.
Bind the Account: Once satisfied with your starter pulls, open the game settings immediately and bind the account to secure your data against unexpected app resets.

Troubleshooting Missing Day 1 Mail

High server traffic at launch can cause delivery delays in automated distribution queues. If your mailbox appears empty after clearing the tutorial:

Return to the title screen and log back in to force a fresh server handshake.
Complete one additional campaign stage to trigger a data sync with the server.
Confirm that you selected the intended regional server shard, as mailbox contents and progress do not transfer across different regional databases.
