Akihisa Yoshii

Personality :

Akihisa is a gentle person, always cheerful and smiling. He cares deeply for his friends, and is always willing to stand up for them no matter the consequences despite his normally carefree and lazy disposition. Unlike his best friend Yuji, his carefree laziness doesn't translate into him looking like a "cool guy." Rather, he's genuinely happy without a care in the world (mostly due to his idiocy). But it is shown throughout the series that Akihisa is aware of his idiocy, and he can put it aside if he applies himself, or if his friends are in danger.

When the going gets tough Akihisa really stands up to the challenge, and gives it his all. His selfless, courageous, and cheerful ways earn him the affections of many romantic admirers both male and female. These include Mizuki Himeji, Minami Shimada, Hazuki Shimada, Toshimitsu Kubo, possibly Yuko Kinoshita, and his older sister Akira Yoshii.

Akihisa is an extremely honest person. While at first glance this would seem to be a side-effect of his low intelligence, when given a chance to cheat on a test he quickly turns it down. Of course he's often honest to a fault, like his frequently tactless observations of Minami's physical appearance.

Though it seems that he gets into trouble a lot his intentions are (for the most part) pure, and it doesn't seem to phase him. He's actually very polite, which is one of the reasons he has so many romantic admirers, but loses his cool when his friends put him directly in the line of fire. It really all flies over his head and he continues on with the next day, not because he's a troublemaker, but rather because he rushes into action without thinking about anything but the sake of his friends. Though he tends to slack off a lot, inside he truly is a golden-hearted person.

Summoned Being :

Although his Summoned Being's battle level is the lowest, he can comfortably stand up against high-class Summoned Beings thanks to his fluent ability to control it from spending time using his shoukanjuu to do jobs for the teachers. With this control, his Being's speed is unmatched, it is highly agile and can execute many unorthodox moves. This has been proven during the fight with Class A, where he takes the belts of the male students speedily and this has enabled him to win battles otherwise thought to be impossible due to his poor grades. However, because he is the Punishment Inspector, the fatigue and damage experienced by his Summoned Being is returned to himself, so he tries to avoid summoning during battles if not necessary.

Akihisa's Summoned Being's wears a modified Gakuran (school uniform) and wields a bokken (wooden sword). The Occult version is "Dullahan (headless knight)", influenced from the feature that 'No head = fool'. As told by the Principal, he is the one that is "distorting the essence of the Test Summon System". Later in light novel, Akihisa's summon is upgraded only with its torso has a dragon picture on its back. When being tested in Future Summon Being, his summon is the adult version of Akihisa and admitting that he never graduated 2nd grade except by pleading.  After the tournament in volume 2, he acquires the Platinum Bracelet (Also known as the Iron bracelet(in the anime) or the Prototype Bracelet), which allows him to summon two Summoned Beings in a battle (each with the average of the original's power). In the anime, the bracelet he acquires only allows him to create a summoning field without the supervision of a teacher. Each depicted bracelet only works with relatively low power levels, as it is defective, and so suits Akihisa and his low grades.
