Movie
Description
Emmeline "Emmy" Altava serves as Professor Hershel Layton's assistant throughout the prequel trilogy. Orphaned young, she was raised by Leon Bronev, a father figure whose influence drove her to secretly join the Targent organization to repay him, all while concealing this allegiance from Layton.

As Layton's assistant, Emmy proves highly capable, providing vital support through sharp investigative work and fieldwork. She frequently wields her camera to document cases, reflecting her passion for photography. Her notable physical agility and proficiency in hand-to-hand combat allow her to protect others in perilous situations. During the events of "Professor Layton and the Eternal Diva," she aids Layton and Luke Triton indirectly by investigating London disappearances. After consulting Dr. Andrew Schrader, she travels to the Crown Petone opera house ruins, rescues Inspector Grosky, and pilots an aircraft to the island where Layton's group is stranded, assisting in the final confrontation.

Emmy's appearance evolves significantly. As Layton's assistant, she wears a collared white blouse under a yellow trenchcoat, a pink bowtie, white leggings, and dark green boots, with her hair past her shoulders. After leaving Layton's team, she adopts a professional look: a loose white shirt, dark gray shorts or pants, a light yellow sweater tied over her shoulders, and short hair.

Her story culminates in "Professor Layton and the Azran Legacy" when her Targent loyalty is revealed. She betrays Layton and Luke at the Azran sanctuary, threatening Luke's life to force Layton into surrendering an artifact to Bronev. Following Targent's defeat, she resigns as Layton's assistant, expresses remorse, and departs Gressenheller University. She later begins a new career as a reporter for the World Times.

Emmy maintains a complex relationship with Layton, balancing genuine loyalty against her hidden Targent mission. She often displays protectiveness toward Luke, though her betrayal strains this dynamic. Her personality combines a feisty yet kind demeanor; she occasionally teases Luke while demonstrating care for his well-being.
