Granblue Fantasy is filled with an enormous variety of awesome characters, most of whom are playable characters that can be drawn in the gacha.
From the very outset, though, you have two faithful companions who never leave your side: the protagonist’s feisty baby dragon-type thing Vyrn, and Lyria, the latter of whom in particular is a big reason I find myself continually drawn back to the game.
While initially appearing to be the same sort of “mysterious young girl” character seen in a wide variety of Japanese role-playing games over the years — and particularly in mobile-social RPGs such as Granblue Fantasy and its peers — Lyria quickly distinguishes herself as a thoroughly pleasant character to have around, making her an ideal companion for you, the player, as you proceed on your journey around this fantasy world.
