It's confirmed that Magikarp Jump to hit the Japanese iOS and and Play Stores tomorrow on May 23rd.
In an earlier post, we took a peek at a few members of Alm’s army in the Fire Emblem Echoes: Shadows of Valentia game, as they’d recently appeared in a certain mobile game you might be playing to get your daily Fire Emblem fix. This time, we’re going to meet Celica and a few members of her merry band of magic-makers and mercenaries—these characters, her closest childhood confidants, boisterously volunteer to join her team when she initially embarks on her journey.
A new Summoning Focus, named Weapon Triangle, is available until June 6.. It highlights the characters Hinata, Azura, Titania, and Cecilia.
