Sana-chan tells Hayama to stop it. And the rest of the girls backs her up. Mami-chan goes as far as to call him a devil and tells him to go back to hell where he, the demon child, came from. It's turned into a girls vs. boys setting.

Title: Our classroom is primate paradise.

The boys are in the bathroom. Hayama is washing the ink off his face. The others are ... well.... Anyway, the boys want to beat up Sana-chan. All Hayama says is, "We'll do it after school."

Babbit Screen: We'll do it after school.

Aya-chan runs in to tell them that Mami-chan has been kidnapped by the boys. Do you remember what she called Hayama? (She called him a devil.) Sana-chan wonders why she gets away with saying worse than that. Tsuyoshi appears and tells her that Hayama respects her as an opponent. Cobra meet Mongoose. Silly moment over, they rush off to save Mami-chan. Tsuyoshi wishes them good luck in stopping Hayama. Sana-chan asks why Tsuyoshi says that. Tsuyoshi says that he likes Hayama and wants to help him with his shortcomings. Sana-chan takes this the wrong way and thinks that Tsuyoshi is in love with Hayama. The girls race ahead. Tsuyoshi bopped by Sana's mallet is behind and denies that he's in love with Hayama. He says that the person he loves is a girl. He loves Sana. Sana says that the only person for her is Rei-kun!

Getting back to Mami-chan. She's in the fountain at the back of the school. Gomi-kun uses a broomstick to push her head into the water. Hayama dares her to repeat what she said earlier.

Sana-chan arrives and helps her out of the water. Seeing Mami-chan cough up the water, she is shaking with anger. Hayama taunts her. She slaps him. He raises his fist. Feel the tension rise.

Okay, serious moment over, back to insanity.

Sana-chan shows some of her moves she learned from Komawari and says that Hayama can't keep up with her skills. Bags of lime powder drop on her. (don't ask me)

She pulls Hayama into an equipment storage room for counseling. She asks him why does he do such stupid things if he gets the best grades in class besides Tsuyoshi. He answers that he guesses he's really that stupid. Sana-chan wants a real answer. She asks him what is wrong with him. He grabs her neck and says that everything is wrong. He's strong. He tells her not to get in his way or something worse will happen. He lets go and walks out. Sana-chan coughs for a moment and then goes on to yell out to Hayama that she is not afraid of him.

Even at work, Sana-chan is thinking of how to get Hayama to stop.

In Child Toy's Physical Education Class, Sana-chan got a prize. It's a personality tester calculator. We'll be seeing this again. Mama is using it.

Mama gives Sana some advice, attack your opponents' weak spot.
