Isuzu Sento

Isuzu Sento is the main female protagonist of Amagi Brilliant Park series who has a stoic personality. She is very quick to point her magical muzzleloader into your face which is demonstrated in the first episode as she did with Seiya. She is usually expressionless, rarely shows emotions and so her voice is monotone. She comes across as cold and blunt occasionally. Despite that facade, she is also very sensitive. Her name originates from 50 Cent.
