Matsumoto Ikumi

About
She is the first girl to enroll in Golden Industrial's 100 year history as a co-ed school. This led to her being proclaimed as some special being and she is forced to take the role of queen. She doesn't actually like this very much. She is kept in her gym clothes.

She is a somewhat meek girl who can put up a brave front if she has no other choice. In a normal situation she is quickly overwhelmed by someone else's will.

She entered the school as she likes drafting up designs.

She was forced to be the queen, but no on really listens to her. The Shitenno, Yamada Reiichi especially, just make up their own conversations and just do what they want. She is gifted many things by them, but does not quite know what to do with them. She is basically just locked up in her room and made to act like a queen.

As the invasion of Golden Industrial HS begins, she makes up her minds and escapes to a classroom via a window. She waits there to surrended to whoever comes first. She meets Amatsugami Hidehiko and is moved to tears by his willingness to actually listen to her. She is also informed of what Yamada has been doing.

She explains the situation and that she immediately surrenders, but she wants everyone to be able to go to Tentei without anyone being killed or left behind. This seems impossible initially, but she thinks up a plan that will sexually humiliate herself to prove she is impure and not some perfect being. Hidehiko is forced to participate, but he doesn't mind.

After the events have climaxed, she agrees to blow up the school and move to Tentei where she finally gets to wear a normal school uniform and have a somewhat normal school life. She still has a huge fan club.
