Sister of Hiroto.
She's best known for stepping in as a coach during the team's intense rivalry with Aliea Academy. Despite her sharp tactical mind and ability to come up with effective strategies on the fly, she's famously reluctant to actually explain what she's doing—fans often joke that getting her to spell out a gameplan is like pulling teeth. She clearly understands combat strategy on a deep level, but she just can't be bothered with the lengthy explanations most coaches would give.
