Collaboration Event

Collaboration Events are a type of story event that feature characters and content from other media franchises. These events typically provide playable characters and summons that can be obtained by simply participating. Since the release of That Time I Got Reincarnated as a Slime: Wedges of the Sky on November 15th, 2024, additional characters and summons have also been introduced via the Collab Draw.

Rewards from collaboration events are only obtainable during the event period. While reruns have happened in the past, they are extremely rare. However, certain events have been added to Side Stories but some are currently unavailable on the Steam client.
