Lyra called him Marshall Sentry in the latest chapter and his surname was mentioned in one of the previous chapters maybe in a premium scene. I'll find the chapter for confirmation.

Update: It's revealed in a premium scene in Chapter 5. I didn't pay for that scene so I went to Youtube and watch the video. So this confirms that Zekei's last name is Sentry. I'll put it in the trivia for Zekei's page.
