from Baka & Test - Summon the Beasts
Shouko Kirishima is the childhood friend of Yuuji Sakamoto. She is the top student in her level and the class representative for Class 2-A. In the story, she is portrayed as a soft-spoken, but highly assertive and intelligent girl. She is described as elegantly beautiful and very popular, like a typical Yamato Nadeshiko, but yet has no boyfriend, which initially created the impression to others that she is a lesbian. Later, it was revealed that the reason for this is because she is madly in love with Yuuji since childhood and acts possessively towards him, to the point of frequently poking out his eyes in order to prevent him from seeing other girls' underwear or swimsuits, applying locks and chains while they are together, using a handheld taser if he is being 'unfaithful' to her, and even attempted to submit a marriage certificate to the civil registrar.

Baka & Test - Summon the Beasts
The story centers around Akihisa Yoshii, the "baka" of the title. His academy rigidly divides up the student body into classes based on the results of tests. The prodigies are in the A class with reclining seats complete with air conditioning, but Akihisa is in F class, the lowest rung of the school ladder which is furnished only with low, decrepit tables and worn-out straw tatami mats. A girl named Mizuki Himeji is actually one of the smartest girls in Akihisa's sophomore year, but she had a fever on test day and was pigeonholed into the F class. Besides Mizuki (who Akihisa secretly adores), the F class also has Yuuji Sakamoto, the class president who has been Akihisa's friend and partner-in-crime since the freshman year. The school happens to have developed experiments to summon fantasy creatures, and Akihisa decides to rally F class to take on the higher-tiered classes and seize their perks. The F class uses the summoned creatures in an all-out battle for school supremacy.
