Konosuba!!

Four anime characters stand in a line against a colorful, patterned background. From left to right, a blue-haired girl raises her arms, a brown-haired boy raises his arms, a girl in a red and black hat raises her arms while holding a small black creature, and a blonde girl raises her arms. They all perform a synchronized, repetitive motion of raising their arms above their heads and then lowering them, with their expressions and poses changing slightly throughout the loop.
