|This article is about a/an ranger in Mashin Sentai Kiramager.|
Sena started out playing piano when she was a kid.
She earned the name Supersonic Princess during her first official career as a karuta player in her younger days. She went to college with Natsume Masaki, who was a senior of Sena's. Eventually, she pursued her new life to be a full-time track and field athlete, where she became famous as of the present day where SCRTC became her sponsor due to her and Natsume knowing each other from college..
A speed demon and daredevil, Sena often proves very excitable due to her track running, and former Karuta careers. That also leaves her with a great love of high speeds. She is also hot-headed due to this, but has a bubbly and empathetic nature, and is a soft person on the inside. She is an eager member of the group, and often charges in the battle headstrong, sword in hand. Although she does have a squeamish side, often shown to be cowardly against the attacks of Darkness Megabeast Mecha Smog Jouki and Catcher Ligany. In episode 37, Yodonna's whip accidentally splits Sena into 5 clones. Each clone is based on an aspect of her personality; namely, Sena 1 (瀬奈1 Sena Ichi), her athletic side, Sena 2 (瀬奈2 Sena Ni), her cute side, Sena 3 (瀬奈3 Sena San), her smart side, Sena 4 (瀬奈4 Sena Yon), her grateful side, and Sena 5 (瀬奈5 Sena Go), her negative side.
