Marishiten is a playable dragon in Dragalia Lost.
One of the twelve great dragons that serve Amaterasu. Warlike and possessed of prodigious strength, she is revered amongst warriors as an icon of certain victory. In a cuter touch, she has a number of little boars that follow her around.
Official Description (Summer Marishiten)
Marishiten, now 100 percent more beach-ready. Not even the sea can cool her fiery temperament. Her only regret is that she can't fight to the fullest with her loyal boarlets pestering her for belly rubs and scritches behind the ear.
