Baka to Test had a rather nice climax for the series with the ESB with class A .

Yoshii and the others are already training with their summoned beings by using the field created by Yoshii's iron bracelet but lately it has been acting all wierd. Yuuji then prepares the class for the battle and decides to use different strategies to win this. The first one came with Hideyoshi taking her sister's uniform and her books which turns out to be a yaoi book and Yoshii is requested to take the book to return to Hideyoshi's sister who did accepted the battle (after beating Yoshii up). Class B was then 1st lead up to diminish the points of Class A as planned thoughtfully by Yuuji as the other classes had owed them when they denied the change of facilities and class C was enraged by the words of Hideyoshi who had wore his sister's uniform to disguise himself. Class A was continuously bombarded by the other classes' attacks but still had stamina to keep going which surprised Yuuji since the students from Class A were more focused on studying and were not athletic. The ESB between Class F and Class A now begins and Yuuji manages to lure them out to the courtyard where some of the Class A students were overpowered by many Class F students. The plan continues to go well till Shouko and Kinoshita finally found Yuuji and the others. However, with their extra training with their summoned beings, Yuuji, Yoshii, Minami and Himeji were about to dodge their opponents' attacks and was able to slowly weaken them. When the reinforcements of Class A arrives, Yoshii uses his sumoned being to break the school bell and blocks their entry to the field by extending the ESB field with his bracelet. When the tables seemed to have turned, Yoshii's bracelet starts to malfunction as it was originally given to a stupid person but had malfunctioned as Yoshii had started studying. The extended ESB field disappears, resulting in parts of the school building to collapse due to the school bell and Shouko and Himeji both fell into the rubbles where they were caught by Yuuji and Yoshii respectively. "Ironman" later comes and saves Yoshii, Himeji and Minami but as they were wondering if everyone was all right, Yuuji's being was defeated by Kinoshita and the battle was won by Class A.

a rather carefully thought plan Yuuji had and this episode did had much impact on each of the characters now. Yuuji isnt actually stupid and had used strategy planning instead of pure knowledge in the ESB battles and he still does care for Shouko. Minami seems to realise that Himeji does have feelings for Yoshii too after seeing her breaking down on Yoshii after she was saved. it would be great if this series had a great ending to it as well, it was an enjoyable episode and an exciting one for the series's climax.
