Yamaguchi Kumiko went down from a bus and ran to Shirokin Gakuin. When she entered the school, she felt challenged.

Kyoto-sensei, (head teacher), was yelling at the principal. He was very upset because the principal hired female teachers. (Shirokin was a school exclusively for boys.) Kumiko and Fujiyama (the other newly hired female teacher with a nice body, *even though I think she's not that pretty in the anime.*), was standing in front of the principal. The head teacher told them to wear tracksuits in school.

The Class 2-4 heard about the two newly hired female teachers and they were very happy because they heard that one of the teachers was with a nice body. Uchi, one of the students, had a camera. He lay down on the floor near the door of the classroom. (I think he was planning to take a picture of the underwear of the female teacher who will enter the classroom.) But then, Kumiko went in. The guys in the class were disappointed when they learned that the short, pig-tailed girl, wearing a red tracksuit, was their homeroom teacher. They wanted Fujiyama to be their teacher.

Kuma, (a fat student, his name was really Kumai, but his friends call him "Kuma" or "bear") went in front of the classroom and planned to scare Kumiko. Kumiko wasn't frightened at all, but she pretended that she was. The whole class laughed and thought that she was very slow and weird. They threw papers on her, and even called her "fool," "bitch," and others…(those were from the subtitles of my vcd.) One guy went inside the classroom and told Kuma to stop. Kuma followed at once and this amazed Kumiko. This guy was Shin Sawada, the class leader. He was red-haired and …….awwww…. so handsome really (gomen …. I got carried away again..). Then Kumiko started introducing herself to the class. When she was writing her name on the blackboard, (of course she was facing the blackboard) one student threw a pachinko ball at her. She was able to dodge it and catch the ball even she was not facing the class. Then the class was amazed. But, she pretended that she was just lucky to catch it, and then she was scared. Shin didn't fall for that act. He began to be suspicious.

Then, classes were finished. Kumiko and Fujiyama were walking. Fujiyama told Kumiko that there were three students in her class that she wanted to sleep with. Then, Shin, with Uchi, Kuma, Noda, Minami, and the other students were watching them from the balcony (I think it was a balcony… or stairs… I kinda forgot but it doesn’t matter.). The others called Fujiyama and whistled at her. Shin was still thinking about the incident that happened earlier. He told Kuma and the others that Kumiko was not an ordinary teacher. The others won’t believe him. Fuji, (Kumiko's dog) came to fetch Kumiko.

Kumiko went home to the Oedo house, (Oedo was a yakuza clan) and everyone called her "Ojou." They were all giving respect to her since she was the successor to the Oedo house. When they asked her how her first day as a teacher was, she told them that her students were calling her "bitch" and were not following her. The men belonging to the Oedo house were mad, and one even wanted to kill the students for that. They were mad because Kumiko wasn't respected at all. Kumiko stopped them, telling them they were just high school kids, and also, if her real identity was known, she would lose her job.

Then, Shinohara-sensei (I think he was a lawyer or somethin' who was a friend of the Oedo group) was talking to Kumiko and told her to do her best in her work. Shinohara was Kumiko's crush (writing this part really annoys me..) that's why, when he left, she was blushing, and was really happy.

The next day, Kumiko went to school and then saw Kuma talking to some seniors. Kuma told his classmates about it. Kumiko found out that Kuma was about to be beaten by those seniors.

Meanwhile, Shin was lying on the grass by the riverside. His phone rang. His classmates told him that Kuma was about to fight the seniors.

The seniors, with Kudou, were already beating up Kuma but Kumiko came, carrying volleyballs. Then the seniors also got her. Kuma was still conscious that's why, she attacked Kuma using her elbow, then he became unconscious. After that, she fought the seniors.

Shin and the others came. Kuma was unconscious, but he was safe. They found the seniors piled up and then beside them was Fuji, Kumiko's dog. Then, Kuma woke up and told them that Yamaguchi came while he and the seniors were fighting. Shin told them that Kumiko was the one who rescued Kuma and fought those seniors. The others still wont believe him. They said that maybe, it was Kumiko's dog who did it. Shin told them that there was no way a dog could pile up bodies like that. But still, the others didn't believe him.

*I kinda forgot the sequence of the story... But this was also the episode when Kumiko saw her picture at the blackboard, with a voluptuous body. "Yankumi" was written on it. She asked the class what "Yankumi" was. They said that "Yankumi" was "Yamaguchi Kumiko" shortened. She liked the nickname they gave her. I think  this happened before Kuma was beaten by the seniors.
