"Tensura" Joint Project with 6 Aquariums Nationwide Starts Feb 27
In preparation for the massive release of That Time I Got Reincarnated as a Slime the Movie: Tears of the Blue Sea, a very exciting joint project is kicking off. This collaboration, called "That Time I Got Reincarnated as a Slime in the Blue Sea," is happening with 6 different aquariums across the country and will be held from February 27th all the way to May 6th. It is a brilliant way for fans to dive into the world of Rimuru while seeing some actual marine life.

The new movie, That Time I Got Reincarnated as a Slime the Movie: Tears of the Blue Sea, which releases on February 27th, is actually set in the sea for the first time in the entire history of the Tensura franchise. This makes the aquarium tie-up very fitting. During the event period, which is being called "That Time I Got Reincarnated: I Dived into the Aquarium of the Blue Sea," the interiors of these museums will be fully decorated with character stand panels and project posters featuring totally original designs. If you have been following the series, you know why That Time I Got Reincarnated as a Slime is a must-watch fantasy epic, and seeing these characters in a real-life sea setting will be quite a treat.
