Vice-Principal Shiraoka

Her colleagues call her 'Shiraoka'. Because she has the full trust of the chairman, she is in charge of Seiwa's communication despite being relatively young. Not only is she young, but she also has a voluptuous body and is physically as good as the current Seiwa players. She is also very capable, to the point that Koyo says, "Despite being young, she is fit to be a vice principal," after seeing how the vice principal greatly strengthened the students' physical strength in just two days during the vice principal candidate training camp.
