Yoshifumi Aoki

is a member of the Student Cultural Society and Taichi's best friend. He is a classmate of Yui, a girl who he constantly confesses his love to. He claims to have loved Yui from the moment he saw her and does not hesitate to show it. Amongst the Student Cultural Society, Aoki can be considered the least serious due to his philosophy of always living carefree. Despite meaning well, his natural goofiness and perverted tendencies often earn him the ridicule of his fellow club members.

Personality
Light-hearted and silly by nature, Aoki, even in the most tense situations, can still manage to crack a joke and be himself. He is also a blatant pervert who is strangely at the same time quite chilvarous, especially when concerning Yui. Aoki has also proved to be a very resilient person as he is mercilessly berated for his antics on a regular basis by his fellow clubmembers, but he never stays down for long.

Key problem
Throughout the course of the series, Aoki is shown to struggle with his inability to help others. Even though he tries as hard as he can, he finds that his cheerful attitude can only accomplish so much.

Appearance
Aoki is a young man with dark hazel eyes. He is the tallest of his friends and his blonde hair is cut down the middle. He is usually seen in his school uniform.

Background History
Aoki originally wanted to join a "Players' club" and despite knowing that Yamaboshi High did not have such a club, he still wrote it down as his first choice. As a result, the school placed him in the Student Cultural Society by default.

When Aoki was in Junior High School, his first love was Nishino Nana. However, Nana eventually moved away due to her parents' work. Later during Aoki's second year of Junior High, a girl in his class died in a car accident. Realizing how fragile life is, Aoki swore to live life freely so that when he meets his end, it will be without regret.

Friends

 * Nagase Iori: The President of the StuCS club. Due to having similar natures, the two are shown to be good friends.
 * Inaba Himeko: The Vice President of the StuCS club. Inaba is often the person to keep Aoki in line when he gets carried away with his antics. Despite all the merciless punishment and insults she gives him, when all is said and done, the two consider each other good friends.
 * Kiriyama Yui: A female classmate and fellow member of the StuCS club. Aoki has made multiple love confessions to Yui in the past and she has turned him down each time, though she gradually warms up to him. Never wavering, Aoki swears to make Yui happy and it is through his efforts that Yui eventually manages to overcome her androphobia. During the Michi Random arc, Aoki declares that, despite feeling useless in the midst of the many phenomenons, as long Yui cares about him, he can keep fighting.

Others
