diyusi (cookie)
Hinase Haruka as Daiyousei in the original Cookie☆. Typically seen with traffic baton, high-visibility vest, and road signs. She has a ponytail instead of a sidetail, pale or white skin, and almost always has her eyes closed.
Originally an unimportant character, getting overshadowed by Cirno and Nadeko. This began to change in 2014 when a BB theater of her directing traffic became a little popular. Then in 2017, OFFSide: DIYUSI began and she became one of the most popular characters in the entire fandom. Her character is almost entirely defined from MADs and fan videos, separate from the original voice drama and anything about Hinase. This would later cause Cirno to drift too, becoming the Security Guard to match DIYUSI's Crossing Guard. She even received her own derivative character in SIYUDI.
