Description
Kiyoka Sendo is a student at Kamui Daimon Comprehensive Academy and serves as the mechanic for the Fourth Platoon of Jenock. She is fourteen years old and a second-year middle school student in class 2-5. She is the younger sister of Daiki Sendo, and his influence was the primary reason she became involved with LBX.

In terms of personality, Kiyoka is notably quiet and stoic, displaying extremely few changes in facial expression and rarely showing her emotions. She dislikes jokes and flattery, and her unique, reserved atmosphere is reminiscent of her brother. Despite her calm and serious demeanor, her fundamental nature is good, and she tends to get along well with more lively and bright individuals such as Catherine, Yuno, and Hanako. She is also one of the tallest female students at Zenoc, alongside Nozomi Sasakawa, which means many of her male peers must look up to her.

Kiyoka's primary role in the story is as a mechanic, responsible for the maintenance and repair of her platoon's LBX units. A notable and recurring ability she possesses is her use of tarot cards. She frequently uses an application on her CCM to draw tarot cards and predict the future. Like her brother Daiki, her predictions have a good hit rate, and the cards she draws often comment on the events and challenges faced by the Fourth Platoon. Throughout the series, specific tarot cards drawn by Kiyoka, such as Death, The Chariot, The Star, and The Devil, are shown to hold particular meanings that relate to the current situation or foreshadow upcoming events.

Kiyoka's development as a character is subtly shown through her actions and increasing engagement with the team. Her motivations are deeply tied to her brother, as she credits him as the inspiration for becoming a mechanic. In one instance, she demonstrated her growing initiative and mechanical skills by participating in the repair of the First Platoon's units, bringing a Dot Phaser unit for the task. A significant moment in her development occurs when she approaches Kageto Kira, explaining that she has long observed the LBX and weapons he has built since enrolling. She then offers him advice, which leads to the creation of a new LBX, Magna Ortus. This event highlights her technical knowledge and her proactive nature in applying it to strengthen her allies, moving beyond her typically passive role.
