Tanaka

Tanaka (田中 Tanaka) is the male protagonist of Ueno-San wa Bukiyou, and serves as Ueno's love interest. His ignorance of the perverse scenarios he's in serve as the main punchline of the episodic series. He is the older brother of Mizuna and Yomogi.

Appearance
Tanaka has short, dark hair and dark eyes. He has a tuft on the top of his head that is genetic, as his sisters also have it.

Tanaka wears a boy's school uniform. His shoes are green in the anime, which suggests green is the color of the 2nd year student's uniform.

Personality
Tanaka-kun is a 2nd year middle school student, who is clueless about Ueno's feelings towards him. He is always late to club meetings, which gives Ueno time to set up inventions to use on him.

During these experiments, Tanaka will sometimes act inappropriately, leading to him feeling up Ueno. He seems oblivious to this being wrong. Despite this, he is disgusted by many of Ueno's other suggestions, like drinking her pee.

Tanaka is harsh towards his sisters when they do something wrong.

Despite all this, he seems to be a caring person. He cares about Ueno's safety, and he comforts his younger sister Yomogi when Minamine yells at her.

History
Tanaka joins the Science Club during his first year (currently unseen)

He is present when Yamashita is recruited to the club.

Ueno
Ueno has a crush on Tanaka, and his ignorance of that fact is the basis of the series. He is subjected to many experiments by Ueno, trying to get him to realize her feeling, or making him fall in love with her. These inevitably fail, but some have brought them closer.

It is hinted that he may like Ueno somewhat. He cares for her safety and comfort, unless he is the cause of her distress. When Unogawa is introduced, he says he is relieved to find out that she and Ueno aren't together.

Puns
Many characters have names that, when grouped together, form a pun. Tanaka is part of the following group(s):
 * The names of the science club members, Ueno (上野), Tanaka (田中), and Yamashita (山下) each contain a character of the phrase 上中下. This phrase loosely translates to: top (上), middle (中), and lower (下), referring to the age of each member.
