Subaru, Emilia, Rem, Ram, and Reinhard are now in the mobile game
As of April 16, a handful of characters from Re:ZERO are available to roll for in SINoALICE. The mobile game's latest collab throws Subaru, Emilia, Rem, Ram, and Reinhard into the mix, and you can get it started with Subaru Natsuki/Sorcerer as a login bonus from now until the event comes to an end on April 30.
You'll have to get lucky to nab the other four characters, which appear in two Grimoire gacha. Emilia/Cleric and Reihard/Breaker are in Moonlit Flower Ch. 1, and Rem/Crusher and Ram/Paladin are in Moonlit Flower Ch. 2. Check out a trailer for the collaboration below.
Running through the limited time A Faraway Vow event will net you additional Arcana for Subaru, as well as other rewards. As for the other characters, Emilia and Reinhard are on display in the first video below, and you'll find Rem and Ram in the second.
