Description
Lina Schiller, also known as Aquilina Schiller or Hitomiko Kira, first appears in the second season of Inazuma Eleven as the new coach of Raimon Institute. She is introduced during a critical moment when the team is struggling against the powerful Aliea Academy. Her background is tied to the Aliea Academy conflict: she is the sister of Hiroto Kira, also known as Xavier Foster, the captain of the Aliea team Genesis, and the daughter of the academy's leader. Her personal history explains her complex motivations—she works undercover to protect players from her father's manipulation and to dismantle the Aliea Academy from within.

Personality-wise, Lina is depicted as serious, reserved, and deeply strategic. She rarely shows emotion and often makes decisions that appear cold or ruthless, such as expelling Axel Blaze from the team. However, these choices are later revealed to be calculated moves to shield the players from greater harm. Her demeanor is that of a shrewd tactician who believes in achieving a larger goal through tough measures, even at the cost of being misunderstood by the team. She is not openly warm, but she genuinely cares for the well-being of the young athletes under her supervision.

Her primary motivation during the Aliea arc is to protect the Raimon players and to stop the abusive training regimes and manipulation happening within the Aliea Academy. Initially, the team distrusts her, but her true intentions gradually become clear. Later, in the third season, she becomes the coach of Neo Japan, a rival team that challenges Inazuma Japan for a spot in the Football Frontier International tournament. In this role, she demonstrates respect for her opponents and continues to develop talent. Years later, in Inazuma Eleven GO, she takes on a more nurturing role as the director of the Don Sol Orphanage, where she guides and supports young footballers, showing a softer, more maternal side that evolved from her earlier strictness.

Her key relationships include her brother Hiroto, whom she seeks to free from their father's influence, and Mark Evans, the captain of Raimon, who maintains faith in her despite her harsh methods. She also has encounters with other coaches and officials such as Seymour Hillman, who entrusts her with the team. Her development arc moves from a secretive, duty-bound figure to a respected mentor who cares for players beyond the pitch.

Notable abilities include her deep tactical knowledge and her capacity to read opponents' strategies quickly. She also possesses a strong will and the ability to make difficult decisions under pressure. In some video game portrayals, she is shown as a capable coach with high-level stats in technical and tactical categories. Overall, Lina Schiller is a multifaceted character whose hidden sacrifices and gradual opening up define her role in the series.
