Preload availability and download size

Pre‑installation is available before launch.

  • PC pre‑install: about 5.3 GB
  • Android and iOS pre‑install: about 2.7 GB

Tip: Pre‑installing reduces patch‑day download time so you can log in as soon as the servers return.

What’s in version 3.7

Version 3.7 wraps up the Amphoreus arc and introduces one new 5‑star character, Cyrene. Banners also rotate returning units across the patch, including Hyacine, Castorice, Tribbie, Mydei, Phainon, and Cipher.

If you plan to play right at launch, watch the maintenance window for your time zone and pre‑install the update. Once servers are live, grab the compensation mail, then dive into the finale of Amphoreus and Cyrene’s banner.
