ルーミャ・ハワワード

A soldier in the Piequartz army who serves Estraea. 

She has a timid and cowardly over-polite manner of speaking, but when faced with someone she doesn’t like, she has an impressive grasp of sarcastic yet polite speech. 

She’s thoroughly faithful to the Big Breast faith, so naturally she looks down on flat and average chests. 

She’s timid, but immensely powerful as a soldier. 
She’s terrified to the core of Estraea’s punishments. 

She has a variety of jobs, including gatekeeper and jail guard, and encounters Haruto’s party in a variety of situations.
