Kana Sasaki is the founder and president of EGIS, who previously worked as a police officer in External Affairs Division X (外事X課 Gaiji Ekkusu-ka) before leaving her job to establish EGIS. She puts up a rather playful facade but shows a serious attitude when handling an alien case and is observant of her workers.
She is a reliable captain who watches over young members while pretending to be vague.
Before the founding of EGIS, Kana had at least come in contact with aliens. She and her partners once saved a Cicada Girl, though she did not want to hand her over to a research facility as planned. Unfortunately, there was nothing she could do for her.
At some point seven years ago, she came across an android named Pirika 03 in a junkyard. She took her in and named her "Pirika Asahikawa", and kept this secret hidden from the rest of the world.
